I can not get the powermizer mode to go over 1 to save my life. I have tried every single combo of
Option "RegistryDwords" "PowerMizerLevelAC=0x3"
Option "RegistryDwords" "PowerMizerLevel=0x3"
Powerlevelsrc 0x3333 0x3322 in my xorg.conf i have tried in my boot/loader.conf i have even tried editing the driver source code src/nv-reg.h and adding the dwords inside the driver and recompiling. Nothing will move this thing past powermizer level 1 out of 3. (trying other nvidia driver versions actually made it run in power level 0 which is worse)
I hope there is an update that fixes this soon.
I would like to thank Nvidia for supporting freebsd.
