I have recently installed FS9 into my new comp. just the standard 256 with 80gb ram. It ( I think ) has this SiS 661FX/Gx Mirage Graphics card. I have with other programs and addons now used 40gb. While running FS it does not run smooth, is a bit jerky. Some times take a few seconds for the images to catch up. When flying my Dreamworld Archer it performs very slow. Am off to see my computer guru this week scan get it upgraded if need be. Please what do I need to get put in. Looking at adding on so photoreal scenery soon. Will I loose what I have installed if I get it upgraded. Cheers.
Have you tried doing a defrag of your system since installing all that?
Oh, and I assume you mean an 80GB Hard drive. 80GB RAM is a LOT!
Perhaps you are meaning that the RAM is 256MB, which isn't very much at all - you'll struggle with quite a few addons if that's all, but I may be wrong...
