Dx9 crash vs dx10 crash

[(TLL)Frosted]

YEsterday I tryed to play in dx9 for a change and I kept crashing 10-20 minutes into games, I went back to dx10 and didnt crash at all. I would play in dx9 if the game wouldnt crash so much

delete out your shaders folder.  I get some instability if i flip between the two, but clearing out that folder it normally is stable.
