Skuzzy,
Is it my imagination, or do framerates get better the longer you are logged in or actively moving about? I ask, because it is almost like new items are being stored in memory (or whatever magic) and after a while my framerates improve by about 10 to 15 fps. Note, this is with vsync disabled for testing.
Another question/ observation: Does it seem to anyone else that framerate in Beta does not interfere with smoothness of graphics down to the low 20s? Below that maybe some, but nowhere near as bad as with the AH2 game play stutter / warp, etc.. I mean, I have only had problems once, and that was with the bomber mission with tons of AI in the clouds, and several patches ago.
