My system specs:
1. Pentium 4 with 2.4ghz
2. 512 mb ram
3. GeForce 4 MX440 (Gateway) with 128mb
4. 60gb hard drive
5. 17" Flta screen (LCD)
6. Sound Blaster Audigy
I have recently purchased CFS3 (took the risk anyways). I was disappointed about it's performance and gravely sadden that I can't return the sim.
But, due to my system specs, my hopes were restored after making a few tweaks on the CFS3 configoration program and by adding the no-cd patch.
After that, the stutters are now reduced to an unnoticable level. Also, the performance has improved. I could finally raise my resolution without a problem.
I am really surprised that such a problem could be fixed that quickly.

The game is good from what I see. The only problem I'm having right now is winning some missions in the campaign. My bombing runs SUCK, and I get blown out of the sky by flak. In short, I need to be trained a little more.

From what you see in this post, you can tell that I might have had an unfair advantage over CFS3.

If you guys still have problems with the sim, after tweaking, I'll have to feel sorry for you people (after wasting money on it, and shocked by it's low-end performance). :-/
