larger environments you can have maps like the size halo 3 where you logup on xboxlive and play a deathmacth
the curent xbox360 demo has a viewfrustrum of 35000 floats i radio 1280x720 the maxium is 55000 floats beyound that you have to cut off mesh and terrain blocks
tone mapping well have you download the xbox360 demo the tone mapping is just fine
it is fraps and then windows media encoder it can not grap all the colors in the scene
the videos is streamed in 1073 kbit and the high deff. video is streamed in 5027 kbit
that why i have put up a high deff. video you can see there is a big defferance in the light and so on.
