Correct, I didn't know you're on Windows 7. 266 or later is your best bet yet. Maybe there are newer drivers? Unfortunately ever since the 190 drivers the affinity situation is somewhat of a mess. >> If all fails, do you have a nVidia contract to talk to?

If feasible for you, try 186 on xp64, which afaik will give you proper performance. It might be that you can do something in your code, but without getting some hints on why this behavior happens with the new multi-GPU driver code we will get nowhere. > But no, I don't have a direct nVidia contact. Try posting your problem on forums.nvidia.com (please post a link here). If I find the time, I'll follow this up on my end and keep you posted.
