A Patch to Re-Enable Hardware PhysX When ATI Card is Present

In this news, we learnt that hardware PhysX is disabled (GeForce GPU and Ageia PPU) when a Radeon is used as main adapter for graphics rendering. Now a patch coded by a guy nicknamed GenL is able to intercept and bypass the routine:

if (isRadeonDetected)
  Disable_HW_PhysX();

The patch intended only for WDDM 1.1 OS (Windows 7) and works for PhysX GPU only (not PPU). But this is not important because PhysX PPU (the Ageia card) support will be removed in PhysX 2.8.3 SDK (NVIDIA, where is your pay back department???).

The PhysX patch is available here:

Ohh I didn’t see that I removed the PhysX hardware or software mode indication in the last FluidMark. I’ll release an update soon with this important field!
