Reoccurring Graphical Bug, Lighting normals
I'm not sure bit I think this started with the latest hotfix.
When I'm in the game for a while, the game begins to run really badly, it turns out what's happening is a shader compile. After its happened I have compiled shaders in the game install shader cache folder.
After this has happened if I start the game again, my lighting it bugged, the sun shines though things in a weird way. the enviro lighting is kind of warped (see image). Looks like normal/dot products are kind of messed up. It seems to only effect Voxel geometry.
Things I've tried:
If I clear the caches (roaming and game install folder) every thing is fine for a while but then it happens again.
Clearing caches and re validating install files.
Deleting shader folder and re-validating and downloading.
I'm AMD graphics, but a few nvidia ppl have mention crashes recently, might be related.
I have the same bug
