Need for Speed Racing Games

Hi guys,
I have a question.. I buy and istall this grat game..but ther's a problem..the game install the Nvidia Psyx...an i have an Ati Radeon Sapphire.. so theres some problem with drives...there's another solution to remove the driver nvidia an give the ati radeon driver for this game??? Thx for all

PhysX comes in two versions, hardware and software. The software only version will be used by ATI cards.

I don't think the hardware version is used even if you have an nVidia card.

The game code decides which PhysX version to use, in this game the hardware version is apparently not used.

So... Don't worry that PhysX is installed when you have an ATI card.
