I'm having some trouble with some pc games. When i log in to play Warhammer online for instance there are textures and in game effects that are wrong or scrambled. The below pictures show pink hills that haven't textured and the other shows an in game pet summoning that should look normal but instead causes the ground to turn hot pink!! Some effects like spells and things also appear as strange geometric patterns.
I know veeery little about PC's (be gentle) and i dont know what to do. I've updated my drivers but that doesn't seem to have helped.
Any help wpuld be greatly appreciated.
