true, very true.some sliders are CPU depended and others are GPU.but no way in the world one can state GPU hardly has any affect on the FPS in FSX.You summed it up pretty well and detailed I must say and I agree with you 100% on your last statement (and the previous ones as well)

Is there a panel.cfg entry that would place a screen on a fourth monitor in full screen mode? I have an ancillary monitor that I re-size and move the PFD and ND to.
