Hi, was after some help please, I've just upgraded my graphics card from a geforce 5200 FX to a 6600 GT, now when I play there are big blue blocks and polygons all over the pitch. This is the same no matter what resolution, quality etc i use in the options setup. I have downloaded the latest drivers from the nvidia website. Anyone have any idea whats causing this and more importantly what I can do to fix it? Thanks in advance.....
