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
  • FXRT (ray tracing): a graphics card with hardware ray tracing, NVIDIA RTX or AMD Radeon RX 6000 and newer, and an up-to-date driver.

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
  • FXPT (path tracing): NVIDIA GeForce RTX 5070 Ti or AMD Radeon RX 9070 XT, or better.

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 Superseded by RageOpenV.asi.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 Superseded by RageOpenV.asi.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 CoreFX's shaders are not drawing, it shows an on-screen warning — "CoreFX: shaders not running". In the main menu or on a loading screen this is normal. If it stays while you play, see Shader Settings > On-screen warnings.
  • Legacy only: Shader Quality has to be High or Very High, and Stereo 3D has to be off.

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.

? Frequently 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, turn Motion Blur Strength down in your GTA 5 graphics settings, or set Image > Motion Blur Strength to 0 in the CoreFX Addon window.
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: shaders not running" message on screen. What does it mean?
CoreFX is loaded, but the game is not drawing with its shaders. In the main menu or on a loading screen this is normal. If it stays while you play on Legacy, check that Shader Quality is High or Very High and Stereo 3D is off, then restart the game. If those are right, or you are on Enhanced, a game update has most likely changed the game's shaders, so update CoreFX to the version made for your game. If you want it gone permanently, the CoreFX Addon menu has a "Hide on-screen warnings" toggle under Options.
What are FXPT and FXRT?
FXPT is CoreFX's own path tracing for GTA V Enhanced: path-traced reflections, global illumination, and lamps and glowing surfaces that light the scene. FXRT is CoreFX's ray tracing for GTA V Legacy: ray-traced sun shadows, ambient occlusion, global illumination and lamp shadows. Both are picked in the Ray Tracing tab of the CoreFX Addon window, and both are off by default. See Shader Settings for what each needs.
How do I use DLSS or FSR on Legacy?
Open the Image tab of the CoreFX Addon window and set Anti-Aliasing to DLSS or FSR. At the game's Frame Scaling 1.000 they anti-alias at full size; below it they upscale. Turn off the game's TXAA and FXAA, and turn MSAA off to upscale. The Running now line in that card shows what is actually drawing the frame.
Can I change the clouds?
Yes. CloudBuilder comes with CoreFX, in the CoreFX\CloudBuilder folder. Make your own clouds there, install them into the game with one click, and pick them under World > Sky > Cloud Pack in the CoreFX Addon window.
