How does ati do physx

This is true of every game you will make in Unity. Also as an aside, I feel that it's pointless for Unity to include PhysX if it's not going to allow GPU support, as GPU support is currently the only thing that makes PhysX a better solution than similar solutions such as Bullet and others. That being said, I understand a lot of gamers have ATI cards, but just as many have an Nvidia card and it would be nice if for those of us who have one, we could at least provide the option for ourselves and players to have enhanced PhysX simulations.

Right now, it's not feasible to include things like cloth in a finished game unless it's the size of a few sheets of paper because of it being on the back of our processors. And it's part of why I shake my head when people say "Hey, let's ask for fluid PhysX!

So, in lamen's terms Built-in support for Nvidia's formerly Ageia's PhysX physics engine,[18] version 2. What does this mean to people that are starting from square one i.

Will it make a difference at any level whether we use an nVidia or ATi card? Anyway, as I said in my answer, physics is totally software-based, the GPU is irrelevant. Physics is totally software-based, including on nVidia cards VivekSridhar : I don't know what you mean by "without PhysX". There isn't any "without PhysX"; Unity is the same on all graphics cards. It doesn't use hardware acceleration for physics at all, but there is nothing missing.

I would like to find out further as I am worried about software and hardware conflicts and my PC is still under warranty. Please help! Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. I'm not sure what the current status of this issue is, but your best resource for the answer is the respective forums for these 2 GPU manufacturers.

Practically all games that use Physx use this poor Physx code. The very latest Physx does have some SSE2 code, but it still is by no means highly optimised - far from it. So, you either take away performance from the graphics, or you have specialised hardware for it - which goes unutilised most of the time.

But some games can be tweaked to give better results. For example, Mafia II and it's cloth crap. Without,you will get error. Are you sure Binary Domain actually uses Physx?

I can't find any information that it does on the web. Binary Domain doesn't even use PhysX. Problem is elsewhere.
