Hello,
I know there has been some discussion on performance issues specific to the NVIDIA Quadro graphics cards with the latest drivers. We have verified that the Quadro FX series also seems to have the similar issues as the K1000/M1000 and K2000/M2000 series.
On a Win7 64-bit machine we verified that drivers 259.57 and 276.28 both had good display performance however newer drivers like 307 and the latest, 320, have very bad graphics performance which was very noticeable with plane metal enabled while zooming in/out of a small board.
Regards,
Jerry
