Fallout: New Vegas is a 2010 action RPG from Obsidian Entertainment, built on the same Gamebryo engine as Fallout 3. Its official minimum requirements ask for a dual-core 2.0 GHz processor, 2 GB of RAM, 10 GB of free disk space and a GeForce 6 series or Radeon X1300 XT class graphics card — hardware from the Windows XP, Vista and 7 era. No official recommended configuration was ever published, so the minimum is the only spec sheet that matters. In practice, almost any desktop or laptop sold in the last decade, including budget office machines and low-power handhelds, will run the vanilla game without difficulty.

Source: the official Fallout: New Vegas Steam store listing (app 22380), checked October 2026. Publishers can update these specs after patches.
The Steam listing for Fallout: New Vegas publishes only a minimum configuration, and Bethesda and Obsidian never issued a recommended tier, so the minimum is the only official reference point. On a modern PC those numbers are trivial to clear: any current processor, 8 GB of RAM or more and any drive with 10 GB free will exceed them by a wide margin. What actually matters on modern Windows is compatibility rather than power. The original executable is 32-bit, so the community 4GB patch is effectively standard, and script extenders such as NVSE along with stability fixes like New Vegas Anti Crash and New Vegas Tick Fix are widely used if you plan to mod the game or play long sessions.
How Demanding Is Fallout: New Vegas Today?
In vanilla form, Fallout: New Vegas is light on both GPU and CPU. It does not stream large high-resolution assets the way modern open-world games do, its VRAM footprint is very small, and it is not a simulation, strategy or large-scale multiplayer title, so there is no heavy background workload for your hardware to feed. What you run into instead are engine limits: the game was designed around a 60 FPS target, and pushing far beyond that can cause physics and timing oddities. In practice your frame rate ends up being decided by the engine and your display’s refresh rate rather than by graphics horsepower.
The picture changes mainly when you mod. Texture overhauls, distant LOD mods and ENB lighting can raise VRAM use and GPU load, while large content mods add strain in dense areas such as the Strip and Freeside. Even then, the hardware required stays modest by modern standards.
Best GPU for Fallout: New Vegas by Resolution
No modern discrete GPU is needed for this game. The tiers below describe what each class of hardware can comfortably handle, measured against the official minimum rather than against any published recommended spec, since none exists.
1080p (Full HD)
Integrated graphics are enough here, and have been for years. AMD Radeon 760M and 780M, the Arc graphics in Intel Core Ultra chips, and even older Intel UHD 630 or Vega 8 solutions all clear the official GeForce 6 series / Radeon X1300 XT baseline by a wide margin, which means the vanilla game at 1080p is usually limited by the engine’s 60 FPS behaviour rather than by the GPU. Older discrete cards such as a GeForce GTX 750 Ti, GTX 1050 Ti or Radeon RX 550 sit far above that baseline too. If you want a modern card anyway, for other games or for heavy texture packs, an RTX 5060 or Radeon RX 9060 XT is already more than New Vegas can use.
1440p (QHD)
1440p remains easy. The same integrated solutions handle the vanilla game without trouble, and any entry-level discrete card from the last several years, such as a GTX 1650, RTX 3050 or RX 6600, is completely unchallenged. At this resolution the practical benefit of a faster GPU is headroom for high-resolution texture packs rather than frame rate in the base game, which is still governed by the engine’s 60 FPS design point and by single-thread CPU speed. A current mid-range card like an RTX 5060 or RX 9060 XT leaves room for any reasonable mod list.
4K (Ultra HD)
4K is the one resolution where a discrete GPU genuinely helps, and mostly once mods are involved. Vanilla New Vegas is old and undemanding enough that modest cards such as a GTX 1660 Super or RTX 3050 will run it, though the engine’s 60 FPS behaviour remains the limiting factor. For a heavily modded 4K setup with large texture packs and ENB, a current mid-range card such as a GeForce RTX 5060 or Radeon RX 9060 XT provides comfortable headroom, and an RTX 5070 or Radeon RX 9070 is more than enough. You do not need a flagship card for this game alone.
VRAM is rarely a concern in vanilla, where usage stays very low. Large texture packs can push usage up at 1440p and 4K, but a card with 8 GB or more is safe for essentially any New Vegas mod list.
CPU, RAM and Storage Notes for New Vegas
CPU
The official minimum is a dual-core 2.0 GHz processor, and the Gamebryo engine is largely single-threaded, so single-core speed matters far more than core count. Any modern processor — an Intel Core i3-10100, Ryzen 5 3600, Core i5-12400 or Ryzen 5 5600, for example — is vastly faster than that baseline and will not hold the game back. This is also not a CPU-heavy genre: New Vegas is not a simulation or strategy game, and the stutter that shows up in dense areas like Freeside and the Strip is an engine limitation rather than a sign that you need more cores. Four to six cores is more than sufficient.
The main CPU-adjacent concern is frame rate itself: above roughly 100 FPS the Havok physics can misbehave, which is why most players and mod guides cap the game at 60 FPS.
RAM
The official requirement is 2 GB. Because the original executable is 32-bit, it cannot address much more than that without patching, which is why the community 4GB patch is treated as essential on modern systems. With the patch, 8 GB of system memory is plenty for the vanilla game, and 16 GB is a comfortable figure if you run large mod lists with hundreds of plugins, since your operating system, browser and mod manager all need memory as well. Memory speed has little measurable effect on this title.
Storage
The official requirement is 10 GB of free space, and a heavily modded install can use two to three times that. Storage does not change frame rate, but an SSD noticeably improves load times and reduces hitching when entering new cells compared with an old mechanical drive. Any SATA or NVMe SSD is fine, and the game will still run from a hard drive, just with longer loading screens.
Example PC Builds for Fallout: New Vegas Today
Because the requirements are so low, a New Vegas build is really just a sensible general-purpose PC that happens to be overkill for this game while remaining useful for modern titles.
Budget / Integrated Graphics Build
This is already more than enough for vanilla and lightly modded New Vegas at 1080p and 1440p. Think Ryzen 5 5600G or Ryzen 5 8600G, or Intel Core i5-12400 or Core Ultra 5, with integrated Radeon 760M/780M or Intel Arc graphics, 16 GB of DDR4 or DDR5 memory and a 500 GB to 1 TB NVMe SSD. With that configuration the game is limited by its own engine rather than by the hardware, and the same system handles esports titles comfortably. No discrete GPU is needed if older Bethesda games and similar titles are your main focus.
Mid-Range Mod-Ready Build
Aimed at players who want a large, stable mod list with texture overhauls and ENB at 1440p or 4K, plus smooth performance in modern games. Think Core i5-14400 or Ryzen 5 7600, 16-32 GB of DDR5, a 1 TB NVMe SSD and a discrete GPU such as a GeForce RTX 5060 or Radeon RX 9060 XT. A build like this removes any hardware limitation for New Vegas, so the remaining work is engine stability and mod compatibility rather than performance.
There is no benefit to going beyond this tier for New Vegas. Faster CPUs and GPUs will not produce a meaningfully better experience in this engine than a mid-range system already delivers.
Laptop and Handheld Gaming: Steam Deck, ROG Ally and More
Fallout: New Vegas is an excellent fit for laptops and handhelds, precisely because it asks so little of the hardware.
On a budget laptop with integrated graphics from the last few years, the game runs exceptionally well. Even thin-and-light ultrabooks with Ryzen 7000/8000 series or Intel Core Ultra integrated graphics handle 1080p without a discrete GPU, and power draw stays low enough for good battery life.
On Steam Deck, New Vegas is widely reported to work well through Proton, and the 4GB patch and common script extenders can be made to work with some manual setup. The ROG Ally, Legion Go and other Windows-based handhelds run it natively without extra tweaks. On any of these devices the sensible target is a 60 FPS cap, since that matches the engine’s design point and keeps the machine quiet and cool.
For handheld play, a controller layout with gyro or trackpad support helps with the Pip-Boy interface, and keeping a keyboard handy is useful for console commands and mod management.
Best Settings to Raise FPS in Fallout: New Vegas
If you do encounter drops, most likely in a modded setup or on very low-power hardware, these options have the biggest impact:
- Anti-Aliasing and Anisotropic Filtering: The in-game MSAA is relatively expensive for its visual benefit. Lowering it from 4x/8x to 2x or off, or forcing FXAA through your GPU driver instead, gives a noticeable boost on integrated graphics with minimal visual loss at 1080p and above.
- Shadow Quality and Shadow Draw Distance: Shadows are CPU and GPU heavy in this engine. Reducing shadow quality or turning off exterior shadows is one of the most effective ways to gain FPS in Freeside and the Strip, where stutter is most common.
- View Distance — LOD and Distant Objects: High object, actor and grass view distances increase draw calls and CPU load. Pulling these sliders back slightly, especially Object Fade and Actor Fade, smooths out frame time spikes in the open desert without hurting nearby detail.
- Water Multisampling and Reflections: Water effects have a disproportionate cost around the Colorado River and Lake Mead. Disabling water multisampling and reducing water reflections helps low-end GPUs and handhelds.
- HDR and Bloom: Disabling HDR and bloom removes a post-processing load and is often preferred by players using ENB presets anyway. In vanilla it provides a small but free gain on integrated graphics.
For stability more than raw performance, keep the frame rate capped at 60 FPS, enable V-Sync through the game or your driver, and avoid running at very high frame rates for long periods. When the game runs well above its intended speed, the Havok physics can cause objects to fly, movement speed to change, and quests to behave incorrectly.
FAQ
Does Fallout: New Vegas need a good PC in 2026?
No. The official minimum is a dual-core 2.0 GHz CPU, 2 GB of RAM, 10 GB of storage and a GeForce 6 series or Radeon X1300 XT class card, and no recommended spec was ever published. Any modern PC, including budget laptops and handhelds, comfortably exceeds that.
Can you play Fallout: New Vegas on integrated graphics?
Yes. Modern integrated graphics such as AMD Radeon 760M/780M and Intel Arc graphics in Core Ultra chips run the vanilla game at 1080p without difficulty. Only heavy texture packs and ENB presets give a discrete GPU a real advantage.
How much RAM and storage do you need?
The official figures are 2 GB of RAM and 10 GB of free space. In practice 8 GB is plenty for the vanilla game with the 4GB patch, and 16 GB is comfortable if you use many mods. An SSD is worthwhile for load times.
Is Fallout: New Vegas CPU or GPU intensive?
Neither, by modern standards. It is an old, largely single-threaded engine, so it leans on single-core speed more than core count, and no current CPU or GPU is stressed by the vanilla game.
