AMD 12.1 previe driver performance

<< < (5/5)

Raistmer:
So, this issue is common for both drivers.
What about -hp switch in menchmark command line? Does it helps ?

Setting the -hp switch with NV_r365 didn't help, but leaving a core free does help (in conjuction with -hp switch), but GPU load is only ~88% now instead of ~98%

Starting the Bench without the -hp switch and a core free also gives ~88% GPU load.

Has there been any Microsoft updates that might have interfered with scheduling/thread priority?

Raistmer:
I don't know about such windows updates.
PErformance drop was reported more than month ago, bug was confirmed... and no more info from NV side.
