I'm using the Mythcenter theme which seems really fast.
I have both settings that I've read are needed to reduce the shared
memory to 64MB...
In my xorg.conf Device section:
Option "RegistryDwords" "RMDisableRenderToSystem=1"
And for the nvidia module, I pass the following options:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222" NVreg_Mobile=0
However, I still get:
(II) NVIDIA(0): NVIDIA GPU GeForce Go 7300 (G72) at PCI:1:0:0 (GPU-0)
(--) NVIDIA(0): Memory: 131072 kBytes
(--) NVIDIA(0): VideoBIOS: 05.72.22.68.00
The underclocking script does seem to be working with a confirmation by
nvidia-settings.
Any clue why this doesn't work for me? I'm running driver 177.
