New camera system - this should fix problems with the camera lag and also make all movement a lot smoother (If you still have problems with camera, make sure Vsync is not the problem)
Easy mode added - if you're not here for the adventure game part, don't want to run around searching for clues or you just get stuck, you can now display hints that will highlight clues and important objects when you get near them. It affects crime scenes and most of the puzzles as well. This will not tell you how to solve the puzzles, just point you in the right direction and show you which objects in the scene are important.
