Radeon X1650

Hey guys. Play fs2004 a lot now but my anti alasing isnt brilliant. I use a Radeon X1650 and sometimes looks like its not on. I have tried using filtering, but that dont work.
I have a not very good system but good enough to play FS2004 OK I think.
1GB Ram
Windows XP Pro
Radeon X1650
AMD Athlon(tm) XP 3200+
2.19GHZ
Any suggestions how to get my anti alasising working properly.
