Rebuilding Shaders Issue

When I logged on last night my video driver kept resetting while the game was loading and the screen never came back. After a hard reboot my AMD Adrenalin was uninstalled somehow.

I reinstalled adrenalin and when I logged into the game it took almost 5mins to load as it rebuilt the shaders. After I finally got in-game I went to a low level map and sat there literally 10mins while the shaders finished rebuilding before the shader and drive stopped running like crazy. I do that because if you try to play while that's happening you get stuttering like crazy and might die.

When I logged in this morning my game had to rebuild shaders yet again even though I didn't have a driver reinstall/crash or anything.

Why is the game rebuilding the shaders so much all of a sudden?

Hey, at least the client IS rebuilding shaders for you...

I've been going into maps to encounter invisible monsters and bosses that do attacks I can't see.
