We already have: Subscribe to the TouchArcade YouTube channel Although this is just a demo (the 40 cars on screen, not Real Racing), so you can't try it out yourself.
There was another tech demo on the front page featuring a bunch of new effects that 3G-S is capable of. I'll try to find it for ya
Thats cool, I've seen it before, but still cool. I think he means more of a tech demo. Right there there is no change in graphics minus the bonus cars, i think he means something like 3d effects an the like maybe?
Tech demo's are always fun to watch. But it doesn't really make any sense for many developers to push the 3GS to it's limit just yet. Maybe in a year or so when people with first gen phone/touches start upgrading.
That real racing test doesn't show much, it just shows it has a faster CPU which we all have now experienced. We need some pixel shader 2 demo! that would be awesome
