I have been playing AH for the past 3 weeks without a problem. I was getting anyhere from 50 - 90 fps. at 1024 x768 with no restrictions selcted in the video options.
However, last week on Thus. night in the CT, I noticed that the mouse was scrolling VERY slowly across the screen. As this was Squad night and we were about to roll, I jumped in my AC and began the take off. The fps got so low that I couldn't get the AC off of the ground and crashed. I jumped back into another AC and managed to get it airborn. The rest of the night I struggled with a slower frame rate, but it had improved from that first take off attempt. When I went to review my film later, the frame rate was in the tank. It was very chopppy, down to <5 fps.
The problem is I can fly AH at anytime and get up to 96 fps and everything is smooth. Then it will decay to the point of 5 fps and down to 1 fps if I fire any guns. This is what I don't understand, one minute its ok and the next its horrible. I don't feel this is a software prob with AH, just a problem with hardware compatibility on my end.
At this point I did the following:
Upgraded the video drivers, no change. Rolled the video drivers back to an earlier version, no change. Went back to the current drivers, no change. I down loaded a freeware app that was supposed to let me adj. refresh rates on my machine according to resolution and refresh rates chosen for a certain game. No change. I have checked virtual memory, and disabled allowable processes to free up resources and still nothing changed. Checking IRQ's I found that Win2K put the sound and video with IRQ11, which is typical with this OS. I have even played other games to see if it effected them as well and they were greatly reduced in performance. I am at my wits end but I feel like I am missing something soooo obvious as to make me look stupid.
