Hi, Bruce. I think we talked about this; I have almost the same system as you with a 2.4ghz cpu, a bit slower, and a 320mb 8800gts, a bit slower, and 2gbs of fast RAM. OFF runs fine with slidders set to planes-5, both terrains on 3, effects and clouds on 4. My fps are 40-60 most of the time with pretty smooth action.. ocassional jerkeness, but nothing upsetting. I use TrackIR5, almost a must for OFF as it has a lousy view system.
I set all the other config settings as per the FAQ's on the OFF site
OFF config settings Incidentally, when you save all the settings you do it by selecting File menu - Exit.
It sounds like somthing is wrong with your install, as you say other games are fine.. maybe reinstall and be sure you update to cFS3 3.1 if you have the older two disk set and fly it first to be sure it is working fine
before installing OFF.. did you do that?
Did you recently buy the OFF DVD and did OFF run OK before you updated to BH&H Phase 3 and Hat in the Ring? Also, Do
not use a no CD exe, this has been known to cause problems.
Also, in your Nvidia panel try switching the settings tab to "Let the 3d application decide"
If you still are having this problem you might want to check at that other place I mentioned.
