As I said earlier. I have PC with 2 OSes installed. On win7 dx11 have glitched textures, vulkan have normal textures but crashes within 30 seconds. On win10 dx11 have normal textures(while videocard driver version which installed on win10 much older than on win7), vulkan insta crashes with error.
Can you say what OS do you use and what happens if you try launch game on vulkan render? It looks like glitched textures occurs on some old nvidia cards and on windows7.
Tried vulkan on win7 - textures become normal but game become dark, freezing(its bad idea to use vulkan or opengl instead directx on amd videocards so nothing unusuial) and it crashing after 10-30 seconds of play.
You a little wrong - I have mentioned that win10 have older driver version. It because I prefer win7 so win10 is abandoned and haven't updated drivers on it since about 2018. It looks like glitched textures appears on some old nvidia cards and on win7.
I think this is a win7 issue. I have a PC(FX-8350, RX470) with 2 OS installed. On win7 I have glitched textures while on win10 doesn't. Also need to mention that version of videocard driver on win10 is older than on win7. I think game pretends to be runnable and playable on win7 like dota and cs.
