I just reformatted my computer. Prior to doing so, my base-line windows user experience score was a 7.6, with 7.7's in both of the graphics categories. After completing my reformat, I installed the latest catalyst drivers (01/27/2009, v10.1). However, I'm scoring a 6.0 in both of the graphics categories, and the device manager has my drivers dated at 12/11/2009, v8.69.
The drivers seem to go in cleanly, other than that. I get no error, and I rebooted after installing them. What might be causing this performance bottleneck?
I'm running Windows 7, 64-bit enterprise. I have an i920 @3.6GHz, an XFX Radeon 5850, and 6GB of RAM.
