6800LE and LFS should play just fine.
It´s an old AGP card -still, I´m using it to race with since 5-6 years, even in 1080p resolution.
Full grid at race start you will get 10-20 FPS, but this only on a very few tracks. Otherwise 35 - 60 FPS
cyklo:
- Like Dave stated: CPU-Z rapport.
- Don´t go 800x600, that for sure will make it look ugly
- Give us some better screenshots ( bigger )
- Play with the settings I marked ( see attached file )
- Test the difference between servers, where there is a lot of objects added, and a "normal" one.
