Altho most of the videos are irritating since they are 12 seconds in length.. A few goodies tho. I noticed he likes to play with no realism. Flying into trees without damaging the plane and whatnot..
I did notice he's playing on a Radeon 4890. Comperable to a Nvidia GTX 275. So just to give you an idea of what to expect. If your running a more recent card. Odds are you'l be able to get better framerate at that level of detail.
