Here is a side by side comparison of the benchmark mode in the game Batman Arkham Asylum regarding PhysX support. On the left is how things look without PhysX and on the right with PhysX on and set to High. By using PhysX you actually get quite more realistic atmosphere and more creepier too while retaining high enough framerate for comfortable play (if you have a fast Nvidia-based VGA or a second dedicated card only for PhysX calculations). But there is more and if you look closely you’ll notice that without PhysX you actually have some objects missing compared to when you have PhysX enabled! The videos were recorded on a machine equipped with GeForce GTX 275 VGA and AMD Phenom II X4 965 BE CPU.
