I see tearing in polygons many times and while running CS i get areas of black darkness in walktest, sometimes, also all CS related apps, PS and QuidDitch, i tried relight on Walktest but no work.
but when i updated PS that fixed the lightning all apps, including walktest were well lighten.
I am getting CS a bit now, it\'s not that bad, it\'s only fired by DirectX SDK users, which were some of my friends they passed these comments, but i think they were not so true.
