So, how well can my graphics card handle this game

[House3988]

I have an antique graphics card: Radeon X300/x550 series 512mb

It can't. I recommend you use FS9. One thing you'll have to understand is that FS is more about processors than graphics cards.

Yeah I had an X350 a year ago. I could run fsx but it was horrible. I did get it to run descently once I went through Nicks recommendations and did a ton of tweaking to the fsx.cfg and changed the size of the trees and clouds. I do not recommend to anyone to tweak the cfg unless you know exactly what your doing. Additionally if you have to tweak your fsx.cfg then you are probably better off just stickin with FS9. This being said you should be able to run FS9 pretty good with that card. But if you want to run FSX you need a new video card.
