When I turn on "Lights" graphics option on it crashes my PC, screen goes black but I can stil hear the audio. It used to happen occassionally, I think it was always in dungeons but I'm not sure - it happend rarely, only few times during my 20ish hours of gameplay and never consistently. Now I can reproduce it everytime in "Oathbinder's Santcum" with autosave after entering this location. To reproduce: I have all graphics settings checked/max, "Lights" turned off. 1. Load save game 2. Turn on "Lights" in graphics menu, close&save menu => crash When I have "Lights" option on before loading a save file it crashes after few seconds or when I move camera up. In windows events log at the time of the crash I found several warnings that driver "nvlddmkm" crashed but recovered and dwm.exe(dwmcore.dll) error 0xc00001ad. It does not happen with any other games, I tested it with some demending games to test the hardware under stress(Oculus Rift games with supersampling turned on to push the GPU). I'm using 1080Ti with newest NVIDIA drivers. I tried reinstalling drivers and also tested older version. Game is on steam with the newest patch Save game is too big to upload, I attached only output_log.txt. There is no crash report in the game folder - I think the game is still running in the background and only the GPU driver crashes but that's just guessing. Any ideas how I could fix it? It's supper annoying, I could just turn this option off and complete this location but game looks so much better with it and I don't want to have it turned off output_log.txt
