Dedicated physX card

Hello,

I was wondering if using a DX10 gfx card as a dedicated physX card will have a drawback in a DX11 game with physX feature.. Does the direct X compability matter in any way in terms of PhysX performance?

Lastly, what would be a good dedicated physX card nowaday?

thanks for the help, much obliged

  1. that would depend on the card.

    a 450/640 would be good now.
  2. It all depends on your main GPU...

    Having a terrible card as a dedicated physX card would degrade your performance...

    So wait... whether my dedicated physx card is dx10 or dx11 compatible won't affect performance?

    Just to clear that up. PhysX is not a part of DirectX. It uses CUDA, a Nvidia gpu acceleration programming language(based on C). If it was a part of DirectX then AMD would have access to it as well(they have access to the cpu based runtimes).
