NVIDIA PhysX on an AMD system?

[WillJackman]

So I recently noticed that I have NVIDIA PhysX installed on my AMD system. Was just wondering what it's doing there and if it might be interfering with anything or causing problems. Or if it's supposed to be there?

Some games use the PhysX software and install the libraries. Since you don't have NV GPU, it will run on the CPU instead. Will be slower but better than nothing.

Or it might be a leftover from a previous (NV) GPU that didn't get uninstalled.

Just to be on the safe side, don't uninstall it.

I've never had an NVIDIA GPU so it won't be a leftover. I'll leave it, was just wondering if maybe it was trying to run on my card and slowing it down or something. Thanks

Nope. The PhysX software won't run on AMD GPUs or even on CPUs, just on nVidia GPUs. It's supposed to offload some of the CPU's workload onto a secondary GPU (or a PPU, if you have one of the really old Ageia cards)>. Like WillJackman said, it was probably installed by a game (i.e. Unreal Engine v3.0+, Unity, Vision Engine v. 6+, etc.) just in case you have an nVidia GPU, but it won't actually do anything if the right GPU isn't there.
