Windows 7: PhysX w/o Nvidia Cards. Only ATI.

PhysX w/o Nvidia Cards. Only ATI.

I only have two XFX-5770 ATI cards in a crossfire configuration.

I also have a Nvidia PhysX programs installed. I assumed they were installed by Steam or some other game.

The questions are;
1) Do I need this PhysX application?
2) Does the ATI cards use them?
3) Will it be safe to delete All Nvidia/PhysX applications.

PS: Never had Nvidia cards installed either.

1. Yes.

2. Not even if you try real hard.

3. You start deleting it then the game(s) that installed it will not work.

For the few games that use Physx it is required. If you have a compatible Nvidia card and the game supports it it will use GPU accelerated Physx, for all others if falls back to a software render and is still required even for this.

Thanks for the info. Glad I did not touch/delete PhysX.
