PhysX System Requirements
by Matt Huston · in Torque 3D Professional · 10/10/2009 (3:57 pm) · 4 replies
A bit of a noobie question but I am curious, what are the system requirements for PhysX? I am mostly concerned about end-user. I was under the impression that some graphics cards have PhysX support and what happens if a user does not have a supported graphic card? Thanks - I am a bit out of the loop when it comes to what is PhysX as it was originally the proprietary physics chip that never took off.

That sounds about right. I have a ATI 4870x2 and of course can run PhysX no problem. I just wasn't sure if this was because nVidia somehow 'shares' this information with ATI.

If you don't it will fallback to software... which is still really fast especially on multicore processors.

If you have an NVidia card then PhysX can use it to accelerate it.If you don't it will fallback to software... which is still really fast especially on multicore processors.

Potentially we will see OpenCL focused implementations in the future with a cut of the PPU, that would be a welcome thing as it would no longer require physx pseudo drivers to be installed and would make a osx version much more likely due to opencl beeing an integrated part of 10.6

Actually PhysX uses CUDA for hardware acceleration, not "NVIDIA specifics" and as such any gpu manufacturer could support it. Its just a fact that ATI does not want to support CUDA (the used techs from NVIDIA for CUDA support are part open source and part commercially licensable from a 3rd party dev unrelated to both).Potentially we will see OpenCL focused implementations in the future with a cut of the PPU, that would be a welcome thing as it would no longer require physx pseudo drivers to be installed and would make a osx version much more likely due to opencl beeing an integrated part of 10.6
