Simply downloading that file won't help. At least it didn't help me in my case.

But I also had to permanently configure my Virtual Memory. I also didn't like the fact that you had to sign up just to download it.

Maybe I'll upload one to Simviation!

Think I'll do that today.
Mathias, I started to realise I was wrong today after I was screwing around at airfields yesterday trying to verify my conclusion. It only happens when vehicles or aircraft are on screen, and only at certain distances, which now leads me to believe it has to do with LODs. I know it has something to to with objects. Since with my first operational CFS3 install, whenever I used to get around specifically placed scenery (cities), FPS would drop through the bucket. Cities cause me no greif now. In fact, the only problem with flying around London or anyplace huge, is getting around those airbases! If I'm at an airfeild, with almost all of it in screen, nothing happens, but as soon as I get those aircraft in the reventments or around the hangars, FPS drops.
I'm pretty sure it has something to do with objects, since I also get the same effect with factories, which usually have aircraft aplenty. I also experienced this when escorting a bomer formation. Far away, nothing happened, close FPS drop, real close, good FPS.

Mathias, you seem to know more about all this than any of us! Any ideas?
