...When it comes to Drivers, just remember the wise old saying...>>>
"Newer is not always better"......!
With many of my previous Graphics cards I have had to experiment with a range of Drivers to find the most suitable, and reliable..and often revert back to older ones!..
(Many times, the Drivers on the CD that came with my Graphics Card often proved to be the best!)
The trick is to always remove all traces of your previous Drivers by running in "Safe Mode" and using Driver Cleaner before installing new Drivers.
F...G-BPLF...
That used to be my rule. It always seemed that the drivers that came bundled with the card worked best.. even years later.
It's a different world now..especially with 8X00 series cards from nVidia, and DX10. The drivers that came with my 8800GTS won't even WORK AT ALL with FSX and DX10
