Note

The FSR4 compatibility list has now been merged into the General Compatibility List

GPUs

  • FSR4 is currently officially supported only on AMD Radeon RX 9000 GPUs and higher.
    • According to a recent announcement by AMD, FSR4.1 will be supported on RDNA3 in July of 2026 and on RDNA2 in 2027.

APIs

  • FSR4 doesn’t officially support Vulkan or DX11 yet.
    • Starting from OptiScaler 0.9, both can be used through a DX12 interop (select FSR3.X/4 w/Dx12 in OptiScaler's upscaler list).
    • Linux currently doesn't support FSR4 VK w/Dx12 as Linux is missing some needed extensions.

Games

  • Since AMD's 25.9.1 drivers, FSR4 can be globally injected through the AMD FSR Upscaling toggle in Adrenalin, adding theoretical support for all FSR3.1 DX12 games that use signed DLLs.

Issues

Table of Contents

FSR4 on Windows 10

  • PotatoOfDoom added experimental support for updating the DirectX 12 Agility SDK which should help games crashing on Windows 10 with FSR4.
    • Set FsrAgilitySDKUpgrade=true in OptiScaler.ini (make sure you have copied the D3D12_Optiscaler folder from the OptiScaler archive into the game folder).

Image Quality

  • If you have image quality issues, please try enabling the Non-Linear settings.
  • FSR4 doesn't officially support Ultra Quality (UQ) preset and may exhibit broken rendering, white screen flashes, flickering, artifacting, etc in some games.
    • Either try the Non-Linear Color Space toggle or use a different preset.

  • RDNA3 on Linux will have broken visuals unless this command is set: DXIL_SPIRV_CONFIG=wmma_rdna3_workaround.

Black artifacts with FSR4.0.1+ in some games

image

  • There are black artifacts present at the top and bottom of the screen during movement, as demonstrated in the image.
  • Seems to happen on some games when FSR 4.0.1+ uses a preset ratio above Quality (1.5), meaning Native AA (1.0) or Ultra Quality (1.3) may cause this issue.
  • Known affected games: Horizon Forbidden West, Cyberpunk 2077, STALKER 2, STAR WARS Jedi: Survivor.
    Workaround:
    • Switch to a preset like Quality or lower.
      or
    • Download the FSR4.0.0 amdxcffx64.dll file and place it in the game folder. OptiScaler will use the local 4.0.0 DLL instead of the global driver's FSR4 for that particular game.
      • To downgrade back to FSR 4.0.0 on OptiScaler 0.7.9+, you'll also have to remove the amd_fidelityfx_upscaler_dx12.dll and amd_fidelityfx_framegeneration_dx12.dll files from the OptiScaler archive and paste the FSR3.1.4 file from the FFX 1.1.4 SDK/OptiScaler 0.7.8 before pasting the FSR4.0.0 amdxcffx64.dll.

FSR4 shimmering on UE DX11

  • Shimmering seems to be related to dilated motion vectors when using DLSS inputs in a DX11 Unreal Engine game.
  • To disable dilated motion vectors, add the following lines into the game's Engine.ini file:
[SystemSettings]
r.NGX.DLSS.DilateMotionVectors=0
  • Check PCGamingWiki in the Configuration file(s) location section to find out where your game's respective Engine.ini file exists.
    • If it doesn't exist, you'll have to create it and make it Read-only if the game deletes it on boot.
  • If you're using Native AA (1.0 scaling), you can disable Display Res. MV under Advanced Init Flags in OptiScaler overlay without editing the Engine.ini file.

Linux Setup

  • FSR 4.1 requires Proton GE 10-34 or any other up-to-date Proton which contains the latest VKD3D, which added FSR 4.1/FFX SDK 2.2 support in order to work
  • Also requires Mesa 25.2+ for FSR4-FG to work and setting Proton prefix to Windows 11 with Winecfg (might require per-game)
    • To downgrade back to FSR 4.0.0 on OptiScaler 0.7.9+, you'll also have to remove the amd_fidelityfx_upscaler_dx12.dll and amd_fidelityfx_framegeneration_dx12.dll files from the OptiScaler archive and paste the FSR3.1.4 file from the FFX 1.1.4 SDK/OptiScaler 0.7.8 before pasting the FSR4.0.0 amdxcffx64.dll.

Setup guide is for Linux Proton with FSR4

  • Use ProtonUp-QT or similar to download and install a supported version of Proton for Steam games. When installing a new version with Steam, make sure that Steam is closed or restart Steam to access the installed version.
  • Grab one of the following:
  • Extract the Proton into ~/.local/share/Steam/compatibilitytools.d/, then either set this Proton globally in Steam as default or manually set game to use it.
  • Env Vars/Settings (e.g Steam Launch Options)
    RDNA4: PROTON_FSR4_UPGRADE=1
    RDNA3: PROTON_FSR4_UPGRADE=1 + DXIL_SPIRV_CONFIG=wmma_rdna3_workaround, and in OptiScaler.ini setFsr4Update=true
  • Make sure to be on Mesa 25.2.0 or newer.
  • Setup OptiScaler as usual and all should work. :)
