Re: 6800GT stuttering
before I switched from NV SW IDE drivers, to the MS standard ones, I couldnt complete 3dMark05.
Screen just went totally black after the first test.
I think it was due to the IDE driver switch, but I was doing alot of meddling at the time, so it can have been the move to Reforce aswell, or something else.
If your not already on the MS drivers, try that and se if it works.
Did you ever try the "blit" settings in RivaTuner? you never answered that I think.
And FC is patched to 1.3 right?
