First.. your running a 9800pro... hes no where near that performance. second, I dont disagree he cant run it, but the frames you posted, you never mentioned your settings and I know for a fact he wont get your fames with his video card.
You know for a fact? You may be surprised how well it runs on a secondary machine, then, with a generic 64mg video card. Sempron 2300, 256megs. 20 gig hard drive. That machine does the exact same thing with fps, limited to 25.
What you guys with monster machines and unlimited gaming budgets forget is how well it runs on slower older machines like mine. I don't run settings all the way to the right, but mostly. I limit cloud draw distance, and the terrain complexity, although I run the slider that does the buildings up pretty high.
What I do NOT do is change scenery files, airport sceneries, clouds or other weather sceneries, water sceneries, don't fly online, fly heavy iron, or use intense aircraft. I don't have trackIR, FSPUIC or whatever that's called, I fly mostly props and a couple of business jets. My sons fly helicopters. I am mostly running an ordinary install of FS. Very little tweaking. The Sempron machine is a complete virgin installation of FS, no tweaking whatsoever. Not even sliders. I installed it for the kids.
To put into perspective hardware-wise, I'm considering moving up to a p4 3.0, and a basic PCIe video card. My intention is to rebuild one of my computers for under $200, reusing components I have now. If I have to buy a more expensive mobo, I'll have to up that a bit.
