If NV techs read this - in this version of the driver, the 450 did not scale to the highest performance mode. I had manually select Prefer Maximum Performance. On the first test the 450 never left level 1. The posted results are from level 2. I did not have to manually scale the 220.
100% agree. My GT430 is constantly going to either level 0 (low performance) or level 1 (medium performance) and the powermizer selection will come back to adaptive after I manually selected "Prefer max performance"...
Is it a bug in the driver?
