Can you highlight where on the image the issue is? I'm not sure i see it
Sure:
Edit: Btw: Some textures/decals sometimes don't seem to load at high resolution (textures set to very high). But don't know if native D3D12 has the same issues (it stutters more though).
I haven't been able to reproduce this ingame at the same spot so far with either amdvlk or radv on my RX 6800. I have a 1080p monitor but tried faking 1440p with gamescope and also tried different upscaling techniques.
Will try again with rdna3 later.
Thanks!
For whatever reason, I now can't reproduce with 100% TAA anymore either. But with any upscaler set to "quality", it triggers the issue:
The issue seems to be caused by XeGTAO.
Okay sorry yes i can reproduce it now.
Attached a Vulkan renderdoc capture made with XeGTAO and XeSS on a RX 6800 with radv 23.3.3. Notice that the right side of the portal is darker which is the side with the glitching (it can move with the camera) https://drive.proton.me/urls/Y0XQZRP5G0#zSl7mhPv75bL
I reproduce this on Windows too.
The portal rendering seems to be contained within a bounding box.
There is an offset applies to the GlobalThreadID when writing the input to XeGTAO buffers.
But in the CS_XeGtaoFinalize pass, there is no offset in the shader, so the portal AO gets a sliced copy.
That causes either darkening or garbage in the right half.
Closing as not our bug.
Thanks for looking into this and your detailed explanation, really appreciated! I guess then it's hardly noticeable on Windows for some random/racy reasons.
Btw. did you notice that some textures aren't streamed in full resolution with VKD3D-Proton? It seems to match the result on Windows when you delete the DirectStorage DLLs there.
Windows with DS:
This is right after loading the level for the first time, no RT.
@Blisto91 Can I convince you to check whether you can confirm the texture issue? :)
There is blocky corruption when looking at rift portals:
Happens with both RADV & amdvlk. Doesn't happen with native D3D12. Issue seems to disappear at some rendering/upsampling resolutions, but happens at most of them and also native 1440p TAA.
