Batman Arkham Asylum CPU PhysX trick: how it works

with one comment

Maybe some of you already heard about PhysX “trick”, that allows GPU PhysX effects in Batman Arkham Asylum to run with decent framerates (~30) on fast CPU ?

There is no magic or hack here, as in this metod MaxPhysicsSubsteps parameter value is reduced to 1 (instead of 5 by default), that result in faster simulation speed, but greather decreased calculations quality.

TheElMoIsEviL has uploaded video to YouTube, that shows how well this trick works:

In the second part of this video, you can notice how papers (simulated by cloth, actually) get stuck in Batman’s character model,  their vertexes are jumping and jittering all over the screen – that’s result of simulation quality trimming.

Use this solution or not – it’s up to you, but if you want to see complex PhysX effects at their best, I’ll need appropriate Nvidia GPU, without alternatives these days.

  1. This is indeed a ‘magic hack’. nvidia and eidos prevent you from using physx effects unless you follow the steps in the provided link
