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

that would depend on the card.

a 450/640 would be good now.

It all depends on your main GPU...

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

What's your main GPU???



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).
