Default Re: 8400M GS : Low performences

On Vista I have changed the registry key PerfLevelSrc from x'3333' to x'3322' with regedit. This forces the GPU to run at max when plugged into the mains, but allows powermizer to still work with batteries. I don't know what other effects this setting might have, so change it at your own risk. My GPU temp when idling now is about 67degC.

x'2222' will keep GPU at max on batteries or mains.

Now my 8400M GS works well with Aero

key is in :
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\{**unique to you for nvidia**}\0000\PerfLevelSrc
