The framerate on my laptop (with a crappy 2 years old ATI card) in an empty level is ~380 fps. If the terrain is visible it drops down to ~140 fps. And it's still in development. I think there's some space for framerate improvement (but I think it's really fast yet).

I can't promise to provide a bunch of HQ assets, but I think that's a good idea. This would be even better if they come along with a small demo level like the Forest Level in CryEditor3.
