I've finally fix my variance issue!
I tried all the advise from skuzzy's tip page and all the advise from other game player's, (sound, programs, connection etc....) none of which were the problem.
If anyone is having a variance problem with the NVIDIA GeForce Go 6800 Ultra 256 meg.
Try this: Go into video settings for the card and turn off
Antialiasing
Vertical Sync
Trilinear Optimization
Triple Buffering
and "Clamp" Negative LOD Bias unless your on wireless leave it "Allowed" for wireless, I have both LAN and Wireless.
This worked for me. I hope it can help someone else in the future:cool:
