If I crank it up to full everything and everything on highest it almost comes to a hault, prolly around 2 or 3 FPS and it is very unflyable, but i am still very satisfied the way everything looks, i always fly at the minimum settings just to be sure it wont get jumpy. Plus, i dont even notice scenery and extra realism after flying for an hr or so, same with reflex, i dont even notice how real it looks once im use to it, i just fly! I tried the free FMS for the heck of it not long ago and the graphics didnt bother me at all, if it had the physics of g3 i would be just as happy.
