Don't know if this is the new version or the patch, but offline, I have been seeing AH running at various speeds, which seem to vary from 100% to 700%. (I know this sounds strange, but read on). Never seen this issue before.
Symptoms are low frame rate, correlating with speeded up motion of objects (such as drones, etc.). Note that the frame rate often starts out at my normal 84, but then after a few seconds drops to this low rate. Exiting the program and reentering usually yields a more normal rate, but sometimes it's still lower than usual (60s at alt instead of 70s/80s). At a frame rate of 10, drones seem to be moving 6 times or more faster than usual, and if I try to take off, plane torque response is speeded up by same factor causing crash soon after starting to move (can't compensate fast enough on rudder).
Online, I have seen this as well, but in less than a minute it seems to synch with the game in some way to produce my normal (pre-2.04) frame rates.
I just updated to DirectX 9.0c, but the problem still occurs. I filmed it, but the film viewer shows it at normal speed, and does not show the screen info display showing the 8-10 fps frame rate. I suppose I could do a screen capture if that would help.
