I just got the S360 recently and the one thing I REALLY wanted to know was how well Counter Strike Source would play on it. I figure I'm not the only one that wants to know how CS Source runs on this machine so I'll post up what I got. I searched many forums and only saw one person write about CSS and his score was decent on 1024 x 768 (~44 fps)

Video Stress Test:

On 800 x 600 I got 77.6 fps

On 1280 x 800 (native resolution) I got ~45 fps (but the screen had alot of purple on it...strange...but this 'purple' did not show up when I played de_dust)

I'm happy that CSS offers you to play it at wide screen but it is stretched wide screen (rather than being able to see more to your right and left). I guess that would let us have the advantage.

Overall I am very satisfied that this runs CSS at a decent rate and and also at good graphic detail.
