Raptor I am running that exact card. It performs okay for AHII.
I ended up working it a little harder at the cost of higher frame rates, but much more stable frame rates.
1280X1024 ( I think..a little beebled on sleemans ale at the moment).
Sliders set to performance, AA is Off, Anisotropic Filtering is off, V-sync is On.
Getting FPS in the high 30's to low 40's. Have seen nothing lower than 26 in a furball on the deck.
Intel Celeron 2.6 GHz
256 MB ram
Your gas mileage may vary depending on system specs etc.
Be aware that it is still a fairly low end card.
Cheers,
RTR
