I just finished benchmarking the 270.19 beta drivers as well as my 275.33 track THE BLACK DEATH in CLOD. The graph attached shows all except Vidcard Memory usage since it had to be on a much larger scale.
Installation Method:
I simply installed the 280.19B over existing driverset 275.33. I did not uninstall existing driver, reboot, installing new driver, and reboot.
I didn't bother overlaying the graphs as I say ZERO differences on all parameters wherein 5 datapoints were recorded each second for total duration of nearly 900 datapoints.
Thought some of you would enjoy the colorful lines

Seen some of you in the RAVENS NEST, hope to you again.
