PhysX Hybrid Setup

So I have a Sapphire 7970 Ghz curently installed in my rig, and I play a lot of games that use PhysX, such as Borderlands 2 and Planetside 2. I'm currently running PhysX with my 3570k, but it is a bit slow at times. Would running a hybrid system with something like a GT 210 give me better performance for PhysX, or would I need a higher end Nvidia card to see performance benefits?

Thanks.

  1. I dont think you can use a physx card when using an AMD gpu as your primary display adapter. If you had a Nvidia gpu as your primary that would help although physx cards dont help by much newer gen cards can run physx at the same time as rendering the game with lil differance

    You definitely can, you can use the AMD card to render graphics and the Nvidia card to do PhysX stuff... you need modded drivers but its definitely possible... I'm just wondering if a cheap card like the GT 210 would perform better than running PhysX off my 3570k (I'm running it at stock, haven't OCed it yet but I assume OCing it would also improve PhysX performance?).
  3. Yeah overclocking it would help improve for sure. Im not 100% sure weather it would be better or not, Id assume the processor would be better at it as thats an old graphics card

    That's what I was thinking, but I've heard things about PhysX being horribly inefficient when run on the CPU (like it only uses a single core or something), and although the 210 is quite old and weak, I was thinking that because it was designed for PhysX (whereas I assume the 3570k was not), it might perform better.
  5. Only way to be 100% would be to test it out but its hard to say how well the game with run on a custom driver thats required to even runna hybrid setup
  6. The 210 is a terrible card for dedicated PhysX. The old Hybrid PhysX hack has not worked on any drivers over the past two years. You might get it to work, but you would have to use outdated drivers. I have heard of possible workarounds, but you would have to do some research, and then, that GT 210 would just slow you down. If you bump up to a current generation GT 640, then maybe.

    The only real way to get PhysX running properly is with an Nvidia card. The CPU is unable to run it very well at all.
  7. Hi

    It is possible but with hacks
    maybe this thread could help.

    Keep in mind that physx is eye candy and the older the geforce card is, the worse the performance will be.

    usually it's not worth it
  8. I don't think the weak 210 will be much faster then your CPU.
