PhysX? On GPU?

Does the PHYSX GPU ACCELERATION option do anything and can PhysX work be forced onto the GPU?

I have the former set to ON and in the NVIDIA Control Panel I have PhysX forced to GPU rather than CPU, but the PhysX Visual Indicator (enabled in that control panel) shows that the game is going with the CPU (if it's using PhysX at all)?

There's a discussion from a couple years ago here but it doesn't seem to have resolved.

    I was under the impression this option does nothing and hasn't done anything in like...forever! lol.

    Don't expect it to come about anytime soon but you never know :smiley:

    It is on the old cdt trello noted as not working.
    (have not checked the new one yet)

    I see. Wouldn't this feature help a lot when CPU-bound? Aren't most people CPU-bound? Seems like an important issue.

    Is there any place (on the Trello e.g.) to formally register interest in prioritizing this?

    ^ It would, but only for NVIDIA owners. Not worth the work and new potential space for bugs in the game.
    Most people are not CPU bound (@ 60 FPS target). Read this thread to know more.

    Nevertheless, is there any tracker where I can register support for this feature?

    You can upvote the page on the CDT trello board, and subscribe to updates so you can see what happens. The problem is, I do not know if the CDT trello board is going to be used going forward.

    We will continue to use the CDT Trello board. It has been already restructured for it's new purpose of collecting Merge Requests. However to be honest votes never made a big differences at Trello. Better use the new feedback portal .

    And the GPU PhysX option does indeed work. NS2 doesn't use PhysX in a way which gets detected by given GPU driver application as we do not use any of the advanced features.

    @GhoulofGSG9 Interesting. What does it do? Does it create some new effects or does it compute something, that would otherwise be computed by other means? Should I have it on or off even if I don't have NVIDIA (to perhaps get some benefit of SSE CPU instructions)?

    Been wondering this for a long time, conflicting information, thanks for clarifying.
