I guess graphics drivers are at fault here. I didn't these glitches when I played it in January: http://steamcommunity.com/sharedfiles/filedetails/?id=913002670 http://steamcommunity.com/sharedfiles/filedetails/?id=913740708
Saw on steamdb a branch with title "Vulkan driver testing". Hope they will fix it soon. And it was updated 1 hour ago https://steamdb.info/app/379720/depots/
This is not RS2 update issue, it was here with Rs1 too.. Check doom thread, there was some talk about it.
If it's what I think it is, then it's been there forever. You need to disable "directional occlusion" in the settings.
Directional occlusion. If disabling it fixes it, you had it before, you just didn't notice. If it doesn't go away when disabling that, then it's a different issue.
whites stripes line noticed long time ago when this game release not in creators update, disable Directional occlusion it helps but AO its lost
I started playing Doom again to find all secrets and noticed a dark and semi transparent "grid" (like OP describes) which was visible on light surfaces outdoors. Funny thing is that I didn't notice this on my first playthrough. Couldn't it be API specific? When I played the game the first time I ran it in OGL mode. Now I use Vulkan (since it's so much faster).
