Well... i don't know if this counts. But let me tell you my situation.
I just installed FSX lastnight and so far i am soooo disappointed
I was really looking forward to it. Let me explain.
I have a Pentium 4 3.04ghz with 2GB 533hz of RAMM, an ATI RADEON X1600 512mb PCI-Express Graphics Card and an 80GB hard drive.
As you can see... my system is not a MONSTER but it is certainly not bad.
I get from 25-30FPS on FS2004 (with my FPS settings at 35). I have changes soooo many settings and have not done much.
I am getting right now 5 - 7FPS....
I don't know what i am doing wrong... as i said i just installed it lastnight....
