I'm new to the MacOSX platform and love it. Won't be going back to regular PC hardware unless absolutely necessary.
I've posed this question in the Apple Support Forums, but the response I'm getting is from someone that doesn't seem to know what they're talking about.
I have the newest fully loaded iMac (3.06Ghz, 4GB Ram, 8800GS video) and I'm having an issue with the GPU and bootcamp. Every time I'm in Vista, then reboot in OSX, the graphics seemed to be under-clocked in OSX. Its seems to be rendering at a power saver setting speed, so games and effects within OSX are slower (by as much as 75%).
My assumption is that Vista's power settings profile is forcing the GPU to down-clock, but its weird cause this still happens if the profile in Vista is set to High Performance. The only fix I've found is to manually re-force the power settings by changing the power scheme in Vista to power saver or balanced, then force it back to High Performance, then immediately reboot back into OSX. Even if it's already set to the High Performance setting, re-forcing this power profile is the only way I can get the full GPU back when rebooting back into OSX. If you let the Vista OS sit idle for more than 5-10mins even on High Performance power scheme, then reboot, the GPU in OSX is underclocked.
Does anyone know of a fix (even if it's command line) that will force the GPU back to full clock speeds in OSX in case I forget to apply this sudo fix before rebooting?
Thanks!
