HT's'answer makes sence as I noticed I get a framerate hits also when zooming througt the prop of the plane sometimes...I've read the wikipedia about fill rate and it says that it is directly proportinnal to the gpu's frequency, so if I manage to get a 10 percent overclock I might see an improvment. It says also that the easy way to test if the problen is fill rate related is to lower the resolution...
Thanks for the input in any case.
And if you want to get oiled easily, up a P47 and make a slow, sloppy attack on a bomber set from behind. Almost guaranteed.
