Borderlands 2: is CPU capable of handling the PhysX effects?

Update #2: Borderlands 2 PhysX Benchmark Roundup

Usually, extra PhysX effects are meant to be executed on compatible NVIDIA GPUs, so even if one can force his CPU to do the work, it is not very effective – massive slowdowns and fps drops during scenes with intence physics are make the games hardly enjoyable. This is valid for titles like Batman series, Alice: Madness Returns, Mafia II and others.

Said matter was a tough topic over recent years, even resulting in claims that NVIDIA “hobbles” the CPU PhysX performance by purpose, to make their GPUs look more advantageous.

However, recently we saw many reports (mostly from AMD users) that Borderlands 2 shows surprisingly good performance, while running with all PhysX effects enabled even without a NVIDIA card in the system.

Thus, we decied to perform a little investigation to answer the question – can a CPU handle all the extra PhysX effects in Borderlands 2 ?

A boss fight against “Boom and his brother Bewm” is a good candidate for PhysX testing – scene contains a lot of particles (also, particles are constantly generated over time) and some cloth objects.

Gun in our hands has explosive rounds - this produces even more particles
