Update.. the new Nvidia 185.85 WHQL
Driver has brought back my problems..
If you did not have any problems with the last Win 7 Driver. this new Signed driver will probably work perfect for you. So don't take my post as a reason to not use the WHQL. but some people are having problems with the Win 7
drivers and there GFX. and I am one of them.
on the last NV Win 7 driver 185.50 right clicking on desktop took about 3 seconds and my 260's were not Downclocking to 2D. I changed and went to the latest Vista 64 182.50 drivers and all those problems went away.
Now with the new WHQL Win 7 Driver my Cards are not going to 2D Mode. eVGA Precision is reading my Memory at 1188 instead of stock 999. and NO overclock will change the readings. So I'm not sure if it's reading it wrong. or it's not working. And now when I right click on my desktop to hit refresh, or enter the NV Control panel. It takes more like 5 seconds for it to come. So it got worse.
Back to the Vista 64 182.50 driver for me for now! ;(
