Fallout 4 System Requirements

To run the Fallout 4 system requirements on PC, you will need an NVIDIA GTX 550 Ti GPU, an Intel Core i5-2300 CPU, 8GB of RAM, and 30GB of HDD or SSD space.

Fallout 4 was released in 2015, so most modern machines won't have any issues meeting the Fallout 4 PC requirements. If you're diving back into the game because of the excellent Fallout TV series, here's everything you need to know to get the game up and running on your PC. 

To meet the Fallout 4 minimum requirements, you will need an AMD Radeon HD 7870 graphics card, an AMD Phenom II X4 945 processor, and 8GB of RAM. Of course, this will only get the game running on the lower end of the graphics presets, and you'll likely encounter performance issues as you head into the ruins at the heart of the Commonwealth. So, we recommend aiming for a higher benchmark.

The Fallout 4 recommended specs call for an NVIDIA GTX 780 GPU, an Intel Core i7 4790 CPU, and 8GB of RAM. Bethesda recommends these specs to play the game as intended. However, if you are looking to install any Fallout 4 mods (we highly recommend Sims Settlements 2), even the recommended specs won't be able to keep up.

Mods hugely expand the scope and demand that Fallout 4 has on your PC. Some mod collections contain more than 500+ mods, so we recommend having an NVIDIA RTX 2070 GPU, an Intel Core i5-10400F CPU, and 16GB of RAM or better if you want a modded version of the game to run well on your PC. You'll definitely want to install the Fallout 4 Script Extender and the Unofficial Fallout 4 patch if you want to get into modding, and want a more stable gaming experience. Just bear in mind that, the more mods you install, the better your gaming hardware needs to be. 

Fallout 4 size

The Fallout 4 download size for PC is 30GB of HDD or SSD space. An SSD is not required, but we highly recommend installing the game onto an SSD to reduce the amount of time you spend on loading screens. You'll hit a lot of loading screens in Fallout 4 as you transition from the large open-world to the numerous indoor locations. So, if you need more space to install Fallout 4, or just want to make an upgrade, check out the PCGamesN buyers guide for the best SSD for gaming.

Fallout 4 next gen update

Bethesda has a massive Fallout 4 update planned for 2024 which it has called "the Fallout 4 next-gen update." The Fallout 4 next gen update is due to go live on April 25, 2024, and brings performance and quality of life fixes to the PS5 and Xbox Series X|S, allowing players to reach 60FPS at increased resolutions. 

For PC players, the update is set to bring widescreen and ultra-widescreen support, and fixes numerous issues to the Creation Kit. Stability, mod, and bug fixes are also included with the next gen update, though Bethesda has not yet listed precisely what they have addressed. 

Alongside the free update, players will be granted access to several Creation Club items for free, including the Enclave Remnants, a Makeshift Weapon Pack, and Halloween-themed items for the Workshop mode.

Unfortunately for modders, this update carries a lot of implications, namely a period of adjustment in which mods are updated to fit around the Next-Gen Update. Already, a DLC-sized mod for Fallout 4 has felt the effects of this upcoming update, with a Fallout London delay having been announced.

Fallout 4 Performance Guide

As an action game, Fallout 4 is best played at impressive graphics with a suitable frame rate to match.

• The Fallout 4 framerate cap is determined by your monitor’s refresh rate, which is typically 60Hz or 120Hz. The standard FPS cap is locked to 60fps on PC, and 30fps on consoles. However, for gamers playing on powerful rigs who desire getting the most out of the game, it is possible to unlock a highter frame rate.
• To unlock the game to run at a higher Fallout 4 framerate, go into the game’s files. Navigate to the “Fallout4Prefs.ini” file in “Documents > My Games > Fallout 4”, open it and search for ‘iPresentInterval=1’. Change the ‘1’ to a ‘0’, save the changes and load up Fallout 4.
• If your system is getting constant low FPS and lag spikes, disabling Vsync can reduce the spikes and increase your FPS. This can be done through the “Manage 3D Settings” section of the Nvidia Control Panel. From here, since the GeForce drivers allow for specific graphics settings for individual games, there is an option to disable Vsync.
• By default, the driver lets the application control this setting, but you can override it to disable Vsync. Vsync is a display option that allows the frame rate of Fallout 4 to synchronize the frame rate with the refresh rate of the monitor for better stability. For example, using Vsync with a 60Hz monitor will cap the frame rate at 60 fps. Turning off Vsync will obtain a higher frame rate, but could introduce negative, unintended consequences onto the game.
