Turning on "Lights" in graphics menu crashes the game in dungeons

[Saffron]

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

Hello Saffron,

 

Thank you for contacting us on the forums! I will get this added if it hasnt already to our database so we can look into why lights may be crashing under specific settings or hardware.

 

Best,

From my observations it may be related to amount of realtime lighting calculations per light source. If your character carry a torch it may increase drastically the load on gpu. In my case using two torches in any environment causes 100% load on gtx 1080 ti, which is... a lot for a Unity based engine rpg.
