View Full Version : ATI cards run Physx with dev drivers without nvidia card

The latest dev SDK kit utilises the Nvidia Physx driver apparently.

http://www.clunk.org.uk/news-stories/does-ati-s-opencl-and-stream-sdk-v2.0-driver-release-utilise-physics-drivers-in-games.html


While running Futuremark's 3D Mark Vantage to check the stability of the drivers, I noticed that the driver tests were clearer, and that some previously unseen (using an ATI card) parts of the test were now visible. As these are normally only seen when running an NVidia graphics card using PhysX, I was intrigued enough to run Futuremark's 3DMark 06 update to see if any there were any further physics utilisations now visible and to my surprise, there were!

These drivers not only gave my humble HD 4890 a boost, but somehow made it faster than ATI's new flagship HD 5870 in both benchmarks. I saw an increase in score of over 900 points in 3DMark Vantage and 2700 points in 3DMark 06 from ATI catalyst 9.9, so the results appear to be impressive so far.

For early beta drivers in a game so "Nvidia'd up" as batman, it dont look bad.

And that was tested with a 4890. Im going to download and install both the drivers and game and see what I get with a 5870.

I hear the also fix White dots in Crysis and a few other things in some games.

Excellent news :)

Can't wait to get my 5870's...

I just updated and installed everything and it dosnt use physx at all. Batman gives the same CPU physx performance. my scores went up in both 3d marks by around 300-400.

Think it only works on the 48xx series thus far.

If these actually enabled PhysX on ATI cards Nvidia will cry.

Probably already are....

I'm not sure ATi can do this, legally. If ATi were to somehow get PhysX to work on their hardware, I'm sure they'd have to be paying some kind of fee to nVidia. If they weren't, then I'm also sure nVidia would have grounds for legal action.

Im pretty sure it dosnt work unless it just dosnt work with the 5 series yet. I sold my 4 series so I cant test.

Not hardly as Nvidia has offered the PhysX library to AMD some time ago royalty free so they could also run PhysX on ATI cards.. Maybe they took the offer afterall.
