This is very cool, but the perspective doesn't seem quite right. See the road as it crosses between monitors[1] in the first video for instance. Of course he's doing this whole thing with crazy multiple game instances so it's fair enough that it's not perfect.

Most games (even AAA titles) have even worse problems with multi-monitor setups, often just staying with a basic rectilinear projection that makes the siides super stretched out.[2] We could do with better camera projection support in games in general.
