Is there a workaround to force PhysX on AMD GPU's ?(Borderland Pre-sequel)

Has anyone successfully been able to force PhysX ,I remember it was possible on borderlands 2 but I can't recall what had to be done.So far I can't seem to make it work for 'pre-sequel'

 

PhysX on AMD GPU? Afaik, this was never possible, but maybe I'm wrong; would like to know more about it though.

One thing to start out with is what version of PhysX Pre-sequel is using. I know nothing about it, but I assume it uses Unreal Engine 3; but not sure if it uses PhysX 2.0 or 3.0.

 

your cpu should be good enough to use it on medium at least

 

Actually it was always possible, it's just a few modules of APEX physx that can't run without an nvidia card, like APEX Turbulence.

You didn't need to do anything special to enable it in BL2, it was a simple menu option, if it's not there in BLPS then I dunno.

 

no, it has never been possible to run physx on AMD gpus, its locked out by the software

you can however, get a low-end nvidia card and run it exclusively on that card with some patching.

 

It is not possible to run physx on amd gpus, and probably will never be as physx is nvidia's proprietary technology which they bought years ago from Ageia PhysX. If you enable physx in game it is rendered by cpu, not gpu. Just by curiosity few days ago i tried to run physx on cpu and i can say it is the best optimized cpu physx implementation i've ever seen but still far from performing any good.

Here are videos i recorded to show how borderlands the pre-sequel cpu physx perform on my hardware:

Low (some people assume it is equal to disabled):

Medium:

High:

Ultra:

This kind of modified driver have never been released and currently is described by many sources as vaporware. Directly from person who was trying to make it i know he didn't make it because amd didn't want to help him by sending sample gpus for testing and he claims that was main reason why he gave up on doing this.

 

Looks like you got an AMD gpu ,how did you enable it ? On my system Physx option is greyed out !

 

Is PhysX GPU or CPU? Not all games allow GPU enabled PhysX. Arma 3 for instance is 100% cpu.

 

You must to have installed physx libraries in your windows. The latest one you can get from nvidia driver (unpack it with 7-zip or winrar and install it from physx folder), installer available at this website is outdated or is at least very rarely updated:

Just little reminder about videos: they were recorded on fx-8320 with default clocks, with better cpu you should get much better performance.

Depends on implementation. Borderlands, metro and other nvidia partnered games are using gpu-accelerated physx with cpu-accelerated when nvidia gpu is not present in system. Trine 2 and Trine 1 Enchanted edition are games using physx but only with cpu-acceleration, not gpu.

 

You want PhysX on a AMD GPU? Just install PhysX(somewhere on the nvidia website), and ur CPU will do all the work.

 

On an AMD/ATI GPU, no.

On an ATI GPU as MAIN and dedicated NV GPU for PHYSX, yes.

EDIT:Fixed. ..If anyone attempts it, don't read too much into it. Looks a lot more confusing/complicated than it really is.

 

I believe You wanted to put this link http://goo.gl/I3TYq :nerd:

Nothing more than in above link is possible IIRC

Edit: ok, above link bit outdated ups, Phantom's is newer..

 

Wrong. All that does is enable the menu option in the game. The PhysX is not run on the ATI GPU, it is still running on the CPU.

 

In borderlands 2, to use Physx without nvidia all you have to do is install Physx software. Before that, it´s greyed out, after that it works using the cpu. In my case i can use Physx on medium on the cpu without performance issues. Haven´t tried the pre-sequel though.

 

There's a simple solution to this misunderstanding. Measure your CPU and GPU usage before and after enabling PhysX.

If CPU usage is relatively the same and GPU usage goes up (during PhysX activity of course), then it's safe to say PhysX is being ran on the GPU. I doubt this is the case though.

If GPU usage is the same, and CPU usage goes up, then PhysX is ran on the CPU still.

And if there's no measurable change at all, then there is some bad optimization somewhere.
