I'm thinking about purchasing this and having a go with it in split-screen, but I'm worried about performance.
While I understand that split-screen requires you to render a scene multiple times, I was wondering what kind of optimizations you guys have in place to speed things up? Do you share resources between the various contexts? Do you re-use physics calculations between the views?
Do you think 4-player split-screen would work smoothly on an Intel Quad-Core@2.5Ghz an Nvidia GTX560, and 8Gb RAM @ 1080p?
