Assassins Creed Origins White lines
Blisto91 opened this issue · comments
Original dxvk issue reported with the Windows driver instead: doitsujin/dxvk#3545
When using amdvlk together with dxvk in Assassins Creed Origins in some scenes, like the present day cave scene after prologue, along the edges of objects a white line can appear at certain angles. This does not happen with radv.
Example screenshot
GPU: 7900XTX
Driver version: 2023Q2.3
dxvk version: 2.2 and current master
apitrace with the issue. When i get out of the cave and look inside again the white lines can be seen at the ceiling at certain angles.

This seems to be related to trunc_coord/truncateCoords, radv disables trunc_coord for textureGather/tg4. I can't repro it anymore with amdvlk when I disable truncateCoords.
There also seems to be a fix for gfx11 with TA_CNTL2.TRUNCATE_COORD_MODE which I can't find in amdvlk: https://gitlab.freedesktop.org/mesa/mesa/-/commit/df6380ddc9c88b37355cb85d2f37697192354aaa
Thanks can confirm it is fixed with 2023.Q3.3
