The problem can be memory.
Some payware need allot of space... some dont.
if you have allot of aircraft, like I had. The fps can nosedive if you dont have proper memory. That is why my new alienware computer will have 4gb.
Sorry, didnt mean to brag. but yeah. Memory can be a big problem. My Current computer only had 67mb left and the max fps were about 20. And no. I have a good graphics card but not one like the 6800.
If I were you. I would enjoy the framerates even if its 20 or 30. Thats still pretty good.
oh no marick, if I got 20 to 30 fps everywhere I flew I would be completely satisfied. I guess I am trying to figure out when is complex scenery and AI too much even for a 6800. Specific example, when I fly into KPHX and there are 9 aircaft on final on one runway, 4 on final in another rwy, 8 waiting for take off clearance, etc, etc... my system starts getting 12 fps and stutters a lot. Those are the kids of situations I am trying to improve on. I would like to learn how much is too much FS for a computer to handle.

Also, you should be proud of your rig. Brag away if you want. I'll let you know when you are going too far. ;)
