Nvidia PhysX on AMD cpu

I was thinking, we often see people getting a Nvidia gpu as a dedicated PhysX card but often when you already have a PhysX card you have the option to offload the PhysX to the cpu. What I am wondering, is that with an AMD processor(let's say 8350), could you offload the PhysX to the AMD processor? Since the 8350 is rarely fully utilized during gaming so it would have the extra muscle lying dormant. Would running PhysX on an AMD cpu like the 8350 be doable or is it not allowed because Nvidia hates AMD?

The Internet is invented by cats. Why? Why else would it have so much cat videos?

It would work. I've tried running PhysX on my i5-3550 and it had decent performance, though it doesn't have to be an Intel CPU you use. You'll have some slowdowns every now and then when a lot of PhysX calculations are going on. But that is to be expected.

I wasn't going for performance, I'm just going for PhysX on the cheap LOL.. So, what you say is that to get PhysX working on a CPU, the CPU doesn't have to be Intel? Can anyone confirm this?

Oh, I know what he means. He means that if he could utilize some of the cores of the 8350 since most of the time it's doing nothing and he wants those cores to be a dedicated PhysX processor. Interesting...

yeah it possible but you have to use a work around driver to enable it so not always the best option. Althought the most ironic thing is Nvidia has enable physX on consoles of which both have AMD platforms.

OP' date=' you're assuming things you shouldn't. PhysX will run on any CPU and the code is intentionally crippled by Nvidia to get people to use Nvidia cards to hardware accelerate PhysX.[/quote']

What I mean is that if you have a system with a Nvidia GPU and a AMD CPU, could you assign the AMD CPU as the PhysX processor? I'm not talking about a hybrid GPU setup here guys.. It will still have a Nvidia GPU in the system, the only difference is that the processor is AMD instead of Intel.

Both Intel CPU's and AMD CPU's are capable of running PhysX.
I know they are capable, but the question is, could I? My scenario is that I have a Nvidia GPU with a AMD CPU in the system.

There is no need for that, PhysX will usually be offloaded to the CPU automatically, unless the developers manually disable it on systems with no Nvidia cards detected.

In that case you can enable it yourself usually through a simple .ini file edit.

And we're not talking about something that's complex. It's your choice in what will process PhysX - CPU or Geforce GPU.
