I'm testing The Talos Principle Reawakened Demo and I noticed a bug that may be related to vkd3d: when global illumination is set to ultra, the water shows some flickering in the distance, see the video below.

The bug is immediately visible in the demo, just turn left as soon as you start.

Software information

The Talos Principle Reawakened Demo (UE5)

System information

  • GPU: AMD Radeon RX 6900XT
  • Driver: tested both RADV (current master) and AMDVLK (current master)
  • Wine version: Proton, current master
  • VKD3D-Proton version: current master, not a regression

I tried playing around with RADV and ACO settings without success.

Log files

There's nothing out of the ordinary in the game logs.

Unfortunately I'm unable to provide a capture because gfxreconstruct freezes the game before the menu, and with renderdoc it doesn't even start.

I noticed the same bug on Windows native D3D12. Probably a game bug. (BTW, the ultra global illumination setting enable lumen reflections in this game)

If this happens on Windows too, this issue should be closed.

I don't have Windows installed at the moment unfortunately, but it seems unlikely to have been mentioned 0 times in the discussions and it's still here after 2 updates, I think it's either a bug in the emulation or something that only happens on AMD.

@HansKristian-Work are you able to get a trace at all?

I just rechecked on Windows and I can confirm this this the same issue, and only happen on the highest Global Illumination setting.

Closing the issue then.
