it is incredible indeed. wow, very nice feelig, lighting, texture work. ground plants look awkward though, but that's an enginedemo, so i'm imressed by the amount of plants it can render.

i checked their realtime lighting demo as well. without lights 600fps, 1 light 250, 2>90, 3>60 ... down to 24 for all lights. still playable, but improvable considering my system (athlon 64 opteron dual core, 2 gig ram, geforce 7600gt)
