playing around with kombustor, checking temps and fps with my hd 6850 and realised my fps was averaging 30ish fps when i had the kombustor window at the front but if i bring another full sized window to the front the fps averages 60. is this normal? also my gpu usage goes to 97%-99% when the kombustor window is behind a window and drops to around 70% when the kombustor window is at the front
