I think those videos and screen shots are pointless to compare the games. You need to see the games running at full res with common setups and play different areas of the demo to get an idea which one is the better choice. It was similiar situation with the just cause 2 demo...
Tested both demo's on the same TV with same leads. Xbox version is better why?
Well first the xbox version has slightly less tearing when inside buildings
Second there is some strange flickering with the trees when driving at speed with the ps3 version. Thought it could be my TV, however this does not occur with the xbox version.
Xbox version has less flickering in the trees when driving at speed and less tearing...preordered the xbox version now
loved "Flower". Hopefully this will turn out well...
