Why does my computer have PHYSX nvidia?

[Glite]

I never knew about this I have a fxf 7770 but in the uninstall options it says, Nvidia PhysX should I uninstall it?

Nvidia Physx can be installed with some games or applications which support it. Don't need to uninstall it, you'll just won't be able to use it.

XFX HD7770 you mean. Did you previously use an Nvidia graphics card? If not then it may be that some game that you are using(like Borderlands 2) has installed the Nvidia PhysX API. Uninstall it if I were you. But yeah, if you arnt having issues with game crashes or graphics artifacts, then dont worry too much.

No. It was installed by a game you have. If you uninstall it the game will give errors and you will not be able to run it. This is common. I to, at one time, wondered the same exact thing until I found out that uninstalling it caused me major issues.

PhysX is not limited to Nvidia GPU's. Many games use PhysX in their game engine, and in order to play that game you have to have the PhysX drivers. In most games that use PhysX, all PhysX takes place on the CPU. Only a few have GPU accelerated PhysX options, which are in addition to the normal PhysX taking place on the CPU. Don't remove them, or what ever PhysX games you have will not work.
