So my game becomes unresponsive if I am in a cave or near an entrance and I put away my torch. For up to several minutes the audio is scrambled and the video is frozen. It remains that way until I bring out the torch which I barely get a second to do so before it freezes again. Only caves and only the torch. The flashlight and light crystals don't fix it. This is gamebreaking, given this is my second save after I lost my first and I know you cannot always have a torch out. This never happend on my previous save. This occurs with and without VR. I put everything on low settings, made my screen windowed and no change. I tested the integrity of the game files and steam says it's all good. The only change is I upgraded to Windows 10 from Win 7 for which I did a complete system wipe and started fresh. I have task manager out to see if I see anything odd is happening and I see nothing to indicate what the problem is. The game is using between 13 and 25% of cpu, about 2gb of DVM or all of it if in VR. The game just stops responding. Any ideas??
