Environment

  • Game: Grand Theft Auto IV Complete Edition
  • GPU: NVIDIA GeForce RTX 4060 Laptop GPU
  • Driver: 581.83
  • OS: Windows 11
  • Resolution: 3840x2160
  • API: D3D9 → DXVK

Issue

A significant color/saturation change appears in GTA IV starting with DXVK 2.5.2.

Comparison

Version Result
Native D3D9 (no DXVK) Correct colors
DXVK 2.5.1 Correct colors
DXVK 2.5.2 Incorrect colors
DXVK 2.5.3 Incorrect colors
DXVK 2.7.1 Incorrect colors

The issue appears as:

  • Strong red/orange tint on character faces
  • Yellow clothing becomes overly saturated
  • Increased contrast
  • Cyan/blue highlights become exaggerated
  • Overall image appears much more vivid than native D3D9

DXVK 2.5.1 looks nearly identical to native D3D9, while 2.5.2 and newer versions exhibit the issue.

Troubleshooting Performed

Tested and ruled out:

  • Windows HDR disabled
  • RTX HDR disabled
  • dxgi.enableHDR = False
  • Removing dxgi.dll
  • Vendor spoof override:
    • d3d9.customVendorId = 10de
  • VRAM override:
    • dxgi.maxDeviceMemory = 8192
  • Same game installation
  • Same GPU driver
  • Same display
  • Same graphics settings

Issue persists on all tested versions newer than 2.5.1.

DXVK Log

Relevant configuration from DXVK 2.5.2:

d3d9.customVendorId = 10de
dxgi.maxDeviceMemory = 8192
dxgi.enableHDR = False

Relevant swapchain output:

Format: VK_FORMAT_R8G8B8A8_UNORM
Color space: VK_COLOR_SPACE_SRGB_NONLINEAR_KHR

So the issue does not appear to be related to HDR output.

Additional Log Warning

Observed only on newer versions:

warn: ConvertFormat: Unknown format encountered: 1396921934

Not sure if related.

Screenshots

I have comparison screenshots showing:

  1. Native D3D9
  2. DXVK 2.5.1
  3. DXVK 2.5.2
  4. DXVK 2.7.1

The regression is visually obvious and reproducible on the same machine.

My game however is smoothest on 2.7.1. But colours are off. On 2.5.1 the colours are correct but game is jittery.

Hi there. Please post a full dxvk log and make a apitrace of the issue if able.
Don't know if you meant to post screenshots like your post maybe implies but they are not included. If you could post them aswell that would be great.

Yes, we know, all Windows+Nvidia users are having issues with color stuff being wrong for some reason and we still can't really do anything about it. If even non-HDR setups are affected then that's just the way it is. None of this ever happens on Proton.

Also obligatory reminder to disable any third-party overlays (including Steam), some of them are known not to interpret sRGB vs linear image formats properly.

Firstly, thanks guys for even responding didnt think that would happen...

Above image is with 2.5.2 and above until 2.7.1

Above is without dxvk

Above is with 2.5.1

I dont know if i am tripping but 2.5.1 looks better in terms of colour - but i dont know if its just not working because it pretty much looks like that without dxvk.

The whole reason i am down this rabbit hole is because ive connected my laptop to my 4k tv, and i would just like it to stop stop jittering, its giving me a headache.

With 2.7.2 it does not jitter but the colours are horrible.

What do i do?

Anything guys?

No? Too much other shit to do right now to focus on some weird Windows jank that we probably can't easily reproduce anyway.

@justepic4life May related or not: try to turn off automacitally manage colour for apps in Windows settings.

This fixed my mouse cursor and potplayer saturation issue which looks nearly same as your screenshot on external monitor.
Note it will need a few minutes to take effect after you turn off it.

Based on my test, this is a universal Nvidia driver issue, not related to DXVK.
To trigger this issue, you must connect at least one 10bit or 12bit monitor on Nvidia output. It never happens on 8bit monitors or connected to Thunderbolt (from iGPU).
Turn HDR on or off changes nothing for me in any condition.

You can confirm your colour bit in Nvidia control panel.

And of course if you just want a quick fix when 8bit colour is acceptable, just go back to 8bit that fix everything.
Note that if you enabled allowFse then game may not follow desktop colour depth, please test without FSE.
Or you can simply output with iGPU or DisplayLink while still rendered by Nvidia, if latency is acceptable.

I don't see much of anything sus in the bisection.
What if you set dxvk.allowFse = True?
