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?
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).
