Hybrid PhysX Patch 1.03 With Reverse Gravity Timebomb Fix

A new version of the PhysX patch that allows a Radeon card (for 3D rendering) to be used with a GeForce card (for PhysX) is available.

If you read the release note there is a pretty shocking thing:

– added support for fixing a timebomb, introduced in 196.75 and 197.xx drivers (gravity reverse + overall slowdown after a few seconds of PhysX processing)

What ? NVIDIA has introduced a timebomb in their ForceWare / PhysX drivers to prevent the use of GeForce with a Radeon ?

Now I understand the gravity reverse effect I saw in this video of FluidMark:



Sometimes reverse gravity can be cool:

Nurien PhysX reverse gravity

Really pathetic from NVIDIA…

I tried to test this patch (HD 5870 + GTS 250) but I didn’t manage to see the PhysX entry in NV control panel in order to enable Physx on the GTS 250. I don’t know what’s wrong with my test system (maybe the NV drivers that are not happy…)..

Anyway, if you’re interessed by this patch you can grab it HERE or HERE.

    Hahaha, reverse gravity! What will they think next?

    Well here’s an idea. How about stopping the fan….of the Radeon this time? lol

    This is going all downhill.
    Shouldn’t there be coming some antithrust probes for those companies.

    ill second fjfjfgjfgj!!

    i said it in the comments here before…this is anti compeditive behaviour..

    end users (us the customers) should be able to use the full features from all hardware we have paid our hard earned cash for..

    fair enough, Nvidia say they wont support ATI rendering+PhysX.. but to blanently create TIMEBOMBS and cripple SOFTWARE drivers and causing problems for users is just totally wrong..morally and ethically!
