I’ve always used this option and it worked with older cards however with Turing it does the opposite: it forces the GPU to stick to maximum performance:
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"
I’ve also tried a kernel module option:
options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1;PerfLevelSrc=0x3333"
With no success.
So, how can I force maximum power saving/minimum performance mode with Turing under Linux? I’m running NVIDIA drivers 450.57. It looks like Xorg options are being ignored.
