i have (of course) the current driver... i mean, that advice is standing in every single ps tech post or faq

but anyway, why should a gfx card error result in a missing polygon? i thought the graphic card would just and calculate and draw the texture, but the problem is that something of the map is missing, or why else should there be no collider?
ahh yes, should have mentioned that i got an "out of bounds position data" error in the system chat-tab, but isnt there any real log of what happened?
