Fallout 4 PC Requirements — Can You Run It on Your PC?

The official Fallout 4 PC requirements call for a 64-bit Windows system, an Intel Core i5-2300 or AMD Phenom II X4 945 processor, 8GB of RAM, a GeForce GTX 550 Ti 2GB or Radeon HD 7870 2GB graphics card, and 30GB of available storage. Bethesda’s recommended specifications raise the processor and graphics requirements to a Core i7-4790 or AMD FX-9590 and a GeForce GTX 780 3GB or Radeon R9 290X 4GB, while keeping the memory requirement at 8GB.

These specifications use hardware from the game’s 2015 release period, so owners of newer PCs must compare component performance rather than model names alone. The published Fallout 4 PC requirements also do not promise a particular resolution, graphics preset, or frame rate. Your likely experience will depend on your exact CPU and GPU, available VRAM, display resolution, selected settings, background software, and whether you install demanding mods or high-resolution textures.

Fallout 4 PC Requirements at a Glance

The official Fallout 4 PC requirements include separate minimum and recommended specifications. Bethesda lists the minimum hardware needed to run the game and a stronger configuration intended to provide additional performance headroom.

These figures come from the official Bethesda Fallout 4 system requirements. The operating systems shown in the table reproduce Bethesda’s published specification; they should not be interpreted as a statement about the current support or security status of older Windows versions.

The words “or equivalent” are important because a PC does not need the exact processors or graphics cards named above. Newer components can meet or exceed the required performance, but a similar product name, memory capacity, or clock speed does not prove equivalence by itself. The complete model and its performance class must be considered.

The minimum Fallout 4 PC requirements are an entry threshold rather than a guarantee of a particular experience. Bethesda does not attach a specific resolution, graphics preset, or frame-rate target to either tier. Meeting the recommended specification therefore provides greater confidence, but it does not officially guarantee 1080p Ultra settings or a constant 60 FPS.

What Minimum and Recommended Requirements Actually Mean

The two official specification tiers answer different compatibility questions. Minimum requirements indicate the lowest hardware class Bethesda lists for running Fallout 4, while recommended requirements describe a stronger configuration with more processing and graphics capacity. Neither tier defines an official frame-rate, resolution, or graphics-preset target.

Minimum is an entry threshold

A PC that meets the minimum Fallout 4 PC requirements should have the necessary hardware class to launch and play the unmodified base game. It may still require reduced graphics settings, particularly in demanding outdoor locations, dense settlements, or areas with long viewing distances.

Meeting the minimum does not guarantee smooth performance in every part of the Commonwealth. Frame rate can change with scene complexity, background applications, component temperatures, driver behavior, and the speed of the individual processor and graphics card. A system that only narrowly qualifies has less capacity to absorb these changes.

The minimum GPU listing also specifies 2GB of dedicated video memory. This is VRAM—the memory used by the graphics processor for textures, rendered frames, and other visual data. It is separate from the PC’s 8GB of system RAM. A computer cannot compensate for a weak graphics processor simply by having more system memory.

Recommended provides more headroom

The recommended Fallout 4 PC requirements raise the processor tier to a Core i7-4790 or AMD FX-9590 and the graphics tier to a GTX 780 3GB or Radeon R9 290X 4GB. This added CPU and GPU capacity gives the system more room to handle complex scenes and higher graphics settings than the minimum configuration.

However, “recommended” should not be interpreted as an official promise of 1080p Ultra settings or a constant 60 FPS. Bethesda’s published requirements do not specify either target. Monitor resolution, selected settings, cooling, drivers, background software, and installed content can all affect the result.

Both tiers list 8GB of RAM, but that does not mean additional memory has no value. Windows, Steam, browsers, recording software, and other programs also consume RAM. A system with more than 8GB may have better operating headroom, particularly when several applications or memory-intensive mods are active, although extra RAM alone will not correct an inadequate processor or graphics card.

How to Check Whether Your PC Can Run Fallout 4

To assess compatibility, compare every major part of your computer with the official Fallout 4 PC requirements. You need the exact names of your processor and graphics adapter, not broad labels such as “Core i5” or “Radeon graphics.”

Step 1: Check your Windows version and system type

Press Windows key + I, then open System > About. Under Windows specifications, note your Windows edition. Under Device specifications, find System type and confirm that the operating system is 64-bit.

Fallout 4 officially requires a 64-bit version of Windows. A 32-bit installation does not meet this condition, even if the computer has sufficient processing power and memory. Bethesda’s requirement table names Windows 7, 8, and 10; that wording should not be treated as current security or support advice for those operating systems.

Step 2: Record your processor and installed RAM

On the same About page, note the full processor name and the amount of installed RAM. You can also press Ctrl + Shift + Esc, select Performance, and open CPU and Memory for more information.

Record the complete model, such as “Intel Core i5-10400,” rather than writing only “Intel Core i5.” Processor families cover many generations, architectures, and performance levels. The family label alone cannot determine whether a CPU meets the Fallout 4 PC requirements.

The game officially requires 8GB of RAM at both specification tiers. Check installed memory rather than currently available memory, but remember that Windows and open applications will use part of that capacity while you play.

Step 3: Identify your graphics processor and VRAM

Open Task Manager, select Performance, and choose GPU. The adapter’s full name normally appears in the upper-right corner. The panel may also display Dedicated GPU memory, which indicates the available VRAM on a discrete graphics card.

For another method, press the Windows key + R, type dxdiag, and press Enter. Open the Display or Render tab and record the graphics-adapter name and display-memory information.

A laptop may show both an integrated GPU and a dedicated GPU. Check every GPU entry and confirm which adapter Fallout 4 uses when launched. Shared GPU memory is borrowed from system RAM and should not be treated as equivalent to the dedicated VRAM listed for the GTX 550 Ti, Radeon HD 7870, GTX 780, or Radeon R9 290X.

Step 4: Check available storage

Open File Explorer, select This PC, and inspect the free space on the drive where Steam will install the game. Bethesda lists 30GB of available space, so the drive must have at least that amount free before installation.

Keeping additional space available is sensible because patches, temporary installation files, downloadable content, Creations, saves, language files, and mods can increase storage use. Compare the requirement with free space, not the drive’s total capacity.

Step 5: Compare every component

Place your CPU, GPU, VRAM, RAM, Windows architecture, and available storage beside the official minimum and recommended specifications. A computer should only be classified as meeting a tier when every required component and software condition satisfies that tier.

You can use the Check Can I Run It game requirements checker to find a game and review its published minimum and recommended specifications. The website does not scan or benchmark your computer, so you must still compare its requirement information with your exact hardware.

A stronger processor cannot replace an inadequate graphics card, and extra RAM cannot supply missing GPU performance. Compatibility depends on the weakest relevant component, which is why the Fallout 4 PC requirements must be evaluated as a complete configuration.

Why Old Component Names Make Comparison Difficult

The Fallout 4 PC requirements use processors and graphics cards that were available around the game’s 2015 release. These parts remain useful reference points, but comparing them with current hardware requires more than matching brand names, model families, clock speeds, or memory capacities.

Model names do not show the complete performance level

Labels such as Intel Core i5, Core i7, AMD Ryzen 5, GeForce GTX, and Radeon RX cover multiple generations and performance classes. A newer processor from a lower product tier may outperform an older high-tier model because processor architecture, instructions completed per clock, boost behavior, cache, memory support, and power limits change between generations.

Core count and clock speed are also incomplete measures. Two four-core processors running at similar advertised frequencies can deliver different results because their architectures process work differently. For this reason, a current Core i5 should not be judged against the listed Core i5-2300 based only on the shared “i5” name.

The same principle applies to graphics cards. A newer model is not automatically faster than every older card, and a higher model number is only meaningful within the correct product generation and class. A useful comparison should consider documented gaming performance, graphics architecture, memory bandwidth, VRAM, and driver support.

VRAM capacity is not the same as GPU performance

Bethesda lists 2GB GPUs at the minimum tier and 3GB or 4GB GPUs at the recommended tier. These capacities describe dedicated video memory, but they do not measure the processing strength of the graphics card.

A slow GPU with 4GB of VRAM does not necessarily meet the recommended Fallout 4 PC requirements. The card must also have enough rendering performance and memory bandwidth. Conversely, sufficient GPU performance does not remove every VRAM limitation, particularly when higher-resolution textures or visual mods are installed.

VRAM demand changes with resolution, texture quality, shadow data, and other graphical assets. If available VRAM becomes constrained, the game may move data between video memory and system memory more often, contributing to uneven frame delivery or delayed texture loading.

Laptop hardware needs separate checking

Laptop and desktop components with similar names can behave differently. A laptop processor or graphics chip may operate within a lower power limit to control heat and battery use. Cooling design, manufacturer settings, and whether the laptop is connected to power can also affect sustained performance.

Some laptops include both integrated graphics and a dedicated GPU. Windows may display both adapters, so the presence of a capable dedicated GPU does not prove that Fallout 4 will use it automatically. The game and Windows graphics settings should be configured to use the high-performance adapter when appropriate.

When comparing a laptop with the Fallout 4 PC requirements, record the complete CPU and GPU names, the amount of dedicated VRAM, and the laptop model. Where available, note the GPU’s configured power level. This provides a more dependable comparison than relying on a family label or the specifications of a desktop card with a similar name.

What Changes Fallout 4’s Hardware Demand?

The official Fallout 4 PC requirements provide a fixed reference, but the workload changes with resolution, graphics settings, background software, storage, and installed content. Two computers that meet the same tier can therefore deliver different results.

Resolution and graphics settings

Higher resolutions require the GPU to process more pixels for every frame. Moving from 1920 × 1080 to 2560 × 1440 increases the pixel count from about 2.1 million to 3.7 million. A 3840 × 2160 image contains about 8.3 million pixels. This increase does not produce perfectly proportional performance changes, but it places more pressure on the graphics card.

Individual settings affect different resources. Shadow quality, shadow distance, god rays, object fade, and distant-object detail can increase graphics demand. Some distance settings may also create more CPU work because additional objects and world elements must remain active. Texture quality is tied more closely to VRAM capacity than to raw GPU speed.

Lowering resolution can help when the graphics card is the limiting component. It may achieve little when the processor is already controlling performance, because game logic, physics, world simulation, and frame preparation continue at the lower resolution.

RAM, background programs, and storage

Fallout 4 officially requires 8GB of system RAM, but the game does not have exclusive access to it. Windows, Steam, web browsers, voice-chat applications, recording software, and security programs consume memory at the same time. Closing unnecessary applications can create more operating headroom on an 8GB system.

Storage type affects loading, not CPU or GPU performance. Bethesda does not require an SSD for the base game, so an HDD can satisfy the published specification. An SSD can reduce the time needed to access scattered game files and may shorten transitions between outdoor and indoor areas, but it should not be presented as a guaranteed frame-rate upgrade.

Treat the listed 30GB as the published base requirement rather than a permanent maximum. Updates, downloadable content, temporary patch files, saves, language files, Creations, and mods can increase the space used by an installation.

Mods, Creations, and high-resolution textures

Mods can change the workload beyond what the Fallout 4 PC requirements describe. The effect depends on what each mod changes rather than the number installed.

High-resolution texture packs can consume additional storage and VRAM. Draw-distance modifications may increase both CPU and GPU demand, while settlement expansions and scripted gameplay mods can add processing and memory workloads. Lighting, weather, post-processing, and visual-overhaul mods may place further pressure on the graphics card.

A system that meets the recommended specification for the original game is not automatically suitable for every mod collection. Requirements should be evaluated against the selected textures, scripts, visual effects, and added world content. Mod authors’ documented prerequisites are more useful than a universal “modded Fallout 4” hardware target.

Updates and current PC editions

Bethesda released a free PC update in April 2024 that added widescreen and ultrawide support alongside stability, quest, mod, and Creation Kit fixes. Unlike the PlayStation 5 and Xbox Series X|S versions, Bethesda’s PC announcement did not introduce separate Performance and Quality modes or promise the console update’s “up to 60 FPS” target for PC. Those claims should not be transferred between platforms.

Later updates continued to address Creations, ultrawide displays, crashes, and mod support. Bethesda’s August 2026 patch also increased the BA2 archive limit to support larger mod collections. These changes are documented in the official Fallout 4 patch notes.

The base game, Game of the Year Edition, and Anniversary Edition differ mainly in their included downloadable content and Creations. As of September 2026, Bethesda’s current support page still publishes the original minimum and recommended hardware table rather than a separate set of Fallout 4 PC requirements for Anniversary Edition. This does not mean every optional Creation or mod will perform within the base-game specification; added content must still be assessed separately.

Recommended Settings for a PC Near the Minimum

A computer that only narrowly meets the minimum Fallout 4 PC requirements should begin with conservative graphics settings. This creates a stable baseline and makes it easier to identify which options the system can handle.

Establish a stable baseline

Start with the game launcher’s Low preset and use the display’s native resolution. Test the game in more than one type of location: an interior, an outdoor settlement, and a dense urban area. A quiet room may run smoothly even when a complex outdoor scene exposes CPU, GPU, memory, or asset-streaming limits.

Pay attention to consistency rather than the highest frame rate seen during a brief test. Repeated pauses, delayed texture loading, uneven movement, or sudden slowdowns provide more useful diagnostic information than a momentary peak.

Before changing graphics options, close unnecessary browsers, recording applications, and other memory-intensive programs. Laptop users should connect the power adapter, select the appropriate performance mode, and confirm that the game is using the dedicated GPU.

Reduce demanding settings in a sensible order

If performance is inconsistent, change one option at a time and test the same location after each adjustment. This makes the effect of each change easier to identify.

Start by lowering shadow distance and shadow quality, since distant and detailed shadows can increase rendering demand. Reduce god rays next, followed by object fade, actor fade, and other distance settings if busy outdoor areas remain slow. These distance controls can affect both the amount of scenery rendered and the work required to manage visible objects.

Keep texture quality appropriate for the graphics card’s dedicated VRAM. Lowering textures can help when memory is constrained, but it may provide little benefit if the GPU’s rendering performance or the processor is the actual limitation. Symptoms such as delayed textures or interruptions when turning quickly can indicate memory or asset-streaming pressure, although they do not prove a single cause.

Reduce the display resolution only if adjustments to the demanding effects do not provide an acceptable result. A lower resolution reduces the number of pixels processed by the GPU, but it will not solve a processor bottleneck.

Avoid blanket configuration tweaks

Do not disable synchronization, remove the frame-rate limit, or edit configuration files as the first response to poor performance. Such changes may introduce screen tearing, uneven frame delivery, timing problems, instability, or conflicts with mods.

Apply one controlled change at a time and keep a copy of any file before editing it. If a change produces no measurable improvement, restore the previous setting. This method is slower than applying a collection of undocumented tweaks, but it makes problems easier to trace and reverse.

What Should You Upgrade First?

Upgrade the component that prevents your PC from meeting the Fallout 4 PC requirements. Replacing a part that already satisfies the recommended tier may produce little benefit if another component remains below minimum.

If the graphics card is below minimum

Prioritize the graphics card when the current GPU lacks the required performance or dedicated VRAM. This is also the most relevant upgrade when the goal is to use a higher resolution, stronger visual settings, or demanding graphics mods.

Before buying a card, check the power supply’s capacity and available power connectors. Confirm that the card fits inside the case and that the motherboard has a suitable expansion slot. The monitor must also accept one of the card’s display connections.

A graphics upgrade cannot correct every problem. Performance may remain limited if the processor is below minimum, the system lacks sufficient RAM, or the power supply and cooling prevent the new card from operating correctly.

If the processor is below minimum

A processor upgrade may help when Fallout 4 slows in locations with numerous characters, objects, scripts, or settlement activity. However, replacing a CPU can involve more than installing a single component.

Processors require a compatible motherboard socket and chipset. Moving to a newer platform may also require a different motherboard, new memory, and a suitable CPU cooler. Check the motherboard manufacturer’s processor-support list and required BIOS version before making a purchase.

For an older computer, compare the cost of upgrading the existing platform with the cost of replacing the motherboard, processor, and memory together. A minor upgrade within an outdated platform may offer poor value if it still leaves the system close to the minimum tier.

If the PC has only 8GB of RAM

Eight gigabytes satisfies Bethesda’s minimum and recommended specifications for the base game. An upgrade is not automatically necessary if Fallout 4 is the main application running and the rest of the system meets the requirements.

Additional RAM can provide more room for Windows, background programs, and memory-intensive mods. It is most useful when Task Manager shows memory usage approaching capacity or the system relies heavily on the page file while playing.

Check the motherboard or laptop documentation before purchasing memory. Capacity limits, module type, speed support, available slots, and matched-channel configurations can affect compatibility.

If storage is the problem

If the installation drive lacks 30GB of free space, remove unneeded files or select another drive with sufficient capacity. Allow additional room for updates, temporary installation data, DLC, saves, Creations, and mods.

Moving Fallout 4 from an HDD to an SSD can shorten loading times and improve file access, but it does not increase graphics-processing power or replace an inadequate CPU. Storage is the correct first upgrade when capacity or slow loading is the main problem, not when the system fails another hardware requirement.

For most players, the best upgrade order depends on the first component below the required tier. Check the full configuration before spending money, because a balanced system is more useful than one powerful component surrounded by unresolved limitations.

Limitations of Requirement Checkers and FPS Calculators

A system-requirements checker can quickly show whether a processor, graphics card, memory capacity, operating system, and storage configuration appear to meet a game’s published specifications. Treat its result as compatibility guidance rather than a performance guarantee.

Automatic detection tools can identify the wrong graphics adapter on laptops with integrated and dedicated GPUs. They may also misinterpret shared graphics memory, unfamiliar component models, or hardware running under unusual power limits. Check the detected information against Windows before relying on the result.

A pass against the minimum Fallout 4 PC requirements means the detected components satisfy the checker’s comparison rules. It does not confirm a particular resolution, graphics preset, or frame rate. Cooling, drivers, background software, game updates, memory configuration, installed mods, and scene complexity can change actual performance.

FPS calculators require similar caution. A useful performance result should identify the processor, graphics card, RAM configuration, operating system, driver, game version, resolution, graphics settings, test location, and measurement method. A number shown without these conditions cannot be reliably applied to another computer.

Average FPS also provides only part of the picture. A game can report an acceptable average while suffering from individual slow frames that create visible stutter. Frame-time consistency and low-percentile results help reveal these interruptions, but only when the test method is properly documented.

Use checkers to identify likely compatibility and possible shortfalls. Use controlled testing to confirm the final experience: begin with conservative settings, examine several demanding locations, and change one option at a time. This combination produces a more dependable conclusion than either a component comparison or an isolated FPS estimate alone.

Frequently Asked Questions

Can Fallout 4 run with 4GB of RAM?

Four gigabytes of RAM is below Bethesda’s official 8GB minimum. The game may launch on some unsupported configurations, but that does not establish dependable compatibility or consistent performance.

Windows and background applications also need memory while Fallout 4 is running. With only 4GB installed, the system may rely heavily on slower storage-based virtual memory, which can contribute to long pauses, poor responsiveness, or instability.

Can Fallout 4 run without a dedicated graphics card?

Bethesda’s minimum Fallout 4 PC requirements specify a dedicated GeForce GTX 550 Ti 2GB or Radeon HD 7870 2GB, or an equivalent GPU. A computer with integrated graphics therefore does not match the published configuration directly.

Some newer integrated GPUs may offer enough processing capability to launch and play the game, but suitability depends on the exact model, system-memory configuration, power limit, resolution, and settings. Shared graphics memory should not be counted as an equal replacement for dedicated VRAM.

Is 8GB of RAM enough for Fallout 4?

Yes. Eight gigabytes meets both the official minimum and recommended requirements for the base game.

The amount available to Fallout 4 will be lower after Windows, Steam, and background applications take their share. More memory can provide useful headroom for multitasking and demanding mods, but it will not compensate for an underpowered processor or graphics card.

Does Fallout 4 need an SSD?

No. Bethesda specifies 30GB of free drive space but does not require an SSD. The game can be installed on a hard drive that has sufficient capacity.

An SSD can shorten loading times and provide faster access to game files. It should not be expected to raise graphics-processing performance or solve a CPU limitation.

How much storage does Fallout 4 need with DLC and mods?

The official base-game requirement is 30GB, but the complete installation can require more space after DLC, patches, language files, Creations, texture packs, and mods are added.

There is no single accurate storage figure for every modified installation. Check the download and installed sizes of the specific content you plan to use, and leave free space for temporary update files.

Did the 2024 update increase the Fallout 4 PC requirements?

Bethesda’s current PC requirements page still lists the original minimum and recommended hardware. The company has not published a separate formal requirement table for the April 2024 PC update or Fallout 4: Anniversary Edition as of September 2026.

The 2024 PC update added widescreen and ultrawide support along with stability, quest, mod, and Creation Kit fixes. Later patches expanded and repaired Creations-related features. These changes can affect installation size, mod compatibility, and behavior, but they should not be described as a confirmed increase in the official Fallout 4 PC requirements.
