Prerequisites

Before installing and using CoreFX, please ensure your system meets these requirements.

Mixing CoreFX with other graphics mods is not recommended and can potentially break your game. Please note that ENBSeries is no longer supported by its developer or by CoreFX. By using CoreFX you automatically agree with these rules.

Legacy Hardware Requirements

  • Minimum: NVIDIA GeForce RTX 2060 Super or AMD Radeon RX 5700
  • Recommended: NVIDIA GeForce RTX 3070 or AMD Radeon RX 6700 XT

Enhanced Hardware Requirements

  • Ray Tracing Minimum: NVIDIA GeForce RTX 3060 or AMD Radeon RX 6600 XT
  • Ray Tracing Recommended: NVIDIA GeForce RTX 4060 Ti or AMD Radeon RX 7700 XT

HDR (Optional, Legacy & Enhanced)

  • An HDR-capable display with "Use HDR" enabled in Windows Display settings. CoreFX upgrades the game to an HDR10 (PQ / BT.2020) swapchain.
  • HDR is switched on in the CoreFX Addon menu (HDR tab > HDR Mode), not in the game. It is Off by default — set it to On. Changing it requires a game restart.
  • Enhanced only: in-game HDR must be off and DLSS enabled. CoreFX HDR and DLSS Frame Generation cannot both run — Frame Generation presents its own frames without passing through the HDR conversion, so the picture stops updating. Turn one of the two off, or install RenoDX's DLSS fix addon beside the game executable.

Software

  • Base Game: A legitimate copy of Grand Theft Auto V.
  • RageOpenV.asi (Recommended, Legacy & Enhanced Singleplayer): A modern replacement for both OpenIV.asi and OpenRPF.asi. Required to load mods from the "mods" folder. (Download from GTA5-Mods)
  • OpenIV.asi (Legacy Singleplayer, Legacy Alternative): Loads mods from the "mods" folder. Comes with the OpenIV app, can be installed inside OpenIV > ASI Manager. Superseded by RageOpenV.asi.
  • OpenRPF.asi (Enhanced Singleplayer, Legacy Alternative): Loads mods from the "mods" folder. (Download from GTA5-Mods). Superseded by RageOpenV.asi.
  • ScriptHookV & Asi Loader (Legacy & Enhanced Singleplayer): Necessary for proper script loading. (Download from dev-c.com). Legacy ASI Loader is dinput8.dll, Enhanced ASI Loader is xinput1_4.dll.
  • CoreFX Package Installer: Bundled with both Singleplayer archives and launched for you by Install.bat — you do not download or run it separately. It installs the .oivs package directly, with no OpenIV app required. (Project page: GTA5-Mods)
  • Note for Legacy FiveM: that package has no installer. It is copied into place by hand — see the Legacy FiveM installation guide.

Required In-Game Settings

  • Shader Quality and Post FX must be set to Ultra (maximum) in the in-game Graphics settings. This is required for the CoreFX shaders to load — at lower settings the game uses different shader variants that CoreFX does not replace, so the mod will look incorrect.
  • If they are set too low, CoreFX shows an on-screen warning — "CoreFX: postfx composite not loaded" — a few seconds after the game starts rendering. Fix the settings and restart the game. (You will also see it while sitting in the main menu, which is normal.)

Optional

  • FiveM (Multiplayer): CoreFX supports multiplayer platforms.
  • Graphics Driver Updates: Keep your GPU drivers up to date.

Licence

  • Every CoreFX archive ships with LICENSE.md (the CoreFX end user licence, version 2.1) and THIRD-PARTY-NOTICES.md. Installing or using CoreFX means accepting those terms — worth a read before you start. Both are on this site: the licence and the third-party notices.
  • CoreFX is distributed only through the CoreFX Patreon page and links published at corefx.me. Copies from anywhere else are not licensed to you.

? Frequency Asked Questions

I don't like blur when moving camera (motion blur). How can I disable it?
For Legacy builds, open the ReShade menu with Page Up, go to the CoreFX Addon window, and turn off Image > Motion Blur (there is also a Blur Intensity slider next to it). For Enhanced builds, disable motion blur in your GTA 5 graphics settings.
Can I use other mods with CoreFX?
It is possible, but not all mods are compatible. Mods that significantly alter the visuals of the game (like other graphics enhancers or weather overhauls) may conflict with CoreFX. Texture replacement mods are generally safer to combine.
Is CoreFX compatible with Singleplayer and multiplayer platforms like FiveM?
Yes. However, installation steps differ for each platform — please refer to the Installation section for detailed instructions.
Where can I find updates and support?
You can join our discord through corefx.me, click on discord logo at bottom-left side of the website
In Rockstar Editor, my recorded clips show a blurred screen when moving. What causes this?
This is caused by in-game motion blur. For Legacy builds, disable it in the CoreFX Addon menu under Image > Motion Blur. For Enhanced builds, turn off motion blur in GTA 5 graphics settings. Important: You must record new clips after disabling it; previously recorded clips will remain blurred. If you spend a lot of time in the editor, Rockstar Editor+ (linked as an optional in the installer) adds a spline camera, camera shake, and removes several of the editor’s built-in limits.
Does CoreFX run on FiveM servers with Pure Mode enabled?
Pure Mode restricts custom client modifications. Currently, CoreFX does not have permission to run under enforced Pure Mode.
How do I open the CoreFX shader menu?
Press Page Up in-game to open the ReShade overlay, then find the CoreFX Addon window inside it — that is where every CoreFX setting lives. Page Down toggles the ReShade effects on and off. This is the same on all builds.
Does CoreFX support HDR?
Yes, on both Legacy and Enhanced. Turn on "Use HDR" in Windows for your display, then open the CoreFX Addon menu, go to the HDR tab and set HDR Mode to On (it is Off by default). It takes effect on the next game launch, because the swapchain has to be upgraded before the game creates its device. Once HDR is active, the tone mapping and colour grading settings in the same tab take effect. On Enhanced, in-game HDR must be off, DLSS must be on, and DLSS Frame Generation cannot be used at the same time.
I see an orange "CoreFX: postfx composite not loaded" message on screen. What does it mean?
CoreFX is installed and running, but its main shaders are not rendering. Almost always this means Shader Quality or Post FX is below Ultra in the in-game graphics settings — fix those and restart the game. You will also see it in the main menu, which is normal. If you want it gone permanently, the CoreFX Addon menu has a "Hide on-screen warnings" toggle under Options.
On FiveM the shader menu is empty or has no settings. How do I fix it?
ReShade and CoreFX.addon64 have to be installed in BOTH places — the FiveM plugins folder and your real GTA V root folder — each with its own CustomShaders folder beside it. Installing to only one location is enough for the addon to show up, but not for it to find its settings. The package ships both copies ready to go; make sure you copied each one to its matching destination.
