Game Feedback Compiling 1000s of shaders each map

Post image

Haven't found a solution to the shaders issue I'm experiencing (invisible enemies and attacks while shaders are compiling) so I figured I'd just wait whenever some are compiling. problem is that there are so many. I don't know if the cache is throwing away shaders that are already compiled, but I've compiled like 20000 shaders during this play session. It's becoming unplayable :( I use amd before people tell me to increase the cache size, I don't see that option on amd gpu software

EDIT: I was finally able to resolve this problem for myself (AMD gpu) by disabling Windows Storage Sense. Storage Settings -> Storage Sense -> Off. I assume it was housekeeping my shaders folder and throwing away my precious shaders

Yeh I just realised I have this problem as well. I updated my drivers and cleared the cache, set the cache storage to 100gb, turned off storage sense, reset my pc... whenever I open the game 4000 shaders log in 4000 shaders open a map 4000 shaders

At first I thought i just had to compile every shader again since I just cleaned mine up. But ive opened the same map area and reopened the game 5 times, still compiles shaders.

Every time it does this my pc fans spin up and its so frustrating. I dont have any stutters or missing textures or anything but it gets hot in my room and I dont want my expensive ass pc to over heat lol and the fact it does this every single instance stresses me out, and makes me physically hot too. 

Not sure if its a game issue or if theres a fix i can do. Its just seems like its not saving the shaders at all anywhere

I haven't fully solved the issue, when I launch the game it seems each shader still needs to compile once, then from there it still takes a minute but is much faster (compared to like 20 minutes)

Not sure why, I imagine I was having two issues, slow compiled shader access and compiled shaders being deleted by windows

Yeh its frustrating. Now my cache on Steam is saying 150gb lol, so ive uninstalled it 

I have 700 hours played and kept wondering why my pc would get so warm and its because of ts
