However when power_dpm_force_performance_level is at auto the speeds don't ramp

When I was in bioshock everything was at it's lowest levels and I was getting
about 3fps, when I echo'd high into power_dpm_force_performance_level I went
back to 17fps, when I echo'd auto back into power_dpm_force_performance_level
the fps stayed high

When I leave the game and relaunch (so the card is re-initialised with runpm)
it goes back to 3fps
