Hi there and thank you for the well made issue. Are you sure it doesn't happen with wined3d? I can see the blue light flicker appearing very shortly a few times at Geralts right hand in the wined3d trace (not the dxvk one), but it seems baked in as it happens both when replayed with wined3d and dxvk. Or did you accidentally switch the traces around?

Tested with my RTX 4080

Thank you for testing, and yes i saw some flickerig on the hand on wined3d and native but not on the level as seen in dxvk, the screenshots show the diference. Also there is some line of light surrounding geralt that is more visible on certain camera positions that it's not present with the gl renderers.

Tomorrow maybe i will create a video to show the diferences and redo the traces.

Ah the outline. I wasn't sure what i was looking at in the first screenshot.

At least for the flickering i haven't been able to reproduce anything on my RTX 4080 that is worse than wined3d or on Windows. It seems to be a game bug that happens at higher resolutions. My monitor is 1080p which i can't reproduce anything with but if i fake a 1440p resolution i can reproduce both with wined3d and native Windows. I'll check it out on AMD later. Also the outline
