3DMark Vantage specifically scales more complexity into a scene to take advantage of additional physics compute resources, which of course is why it looks so different/better on a test run with PhysX processing on our GPUs. This isn't a graphics test it's a physics test. And of course this is true, just as the screen results look different when you test on a dual-core CPU versus a quad-core. It has been said that the tests results look different on the screen when running with PhysX enabled on the GPU. The only thing that changes is that installer, nothing else.

No software libraries or even a line of code changes in the benchmark whatsoever. Nothing within the benchmark is changed at all. NVIDIA, Taylor: During the benchmark install, a runtime library is updated to allow the test to run on the GPU and then during the test, it addresses the benchmark DLLs to the GPU instead of the PPU or CPU.

Could you explain exactly what is being done currently in your new set of PhysX-enabled drivers with respect to 3DMark Vantage, the software libraries that may or may not be replaced, and the impact it has on the benchmark?

HotHardware: We recently became aware of the accusation being thrown about in the industry regarding NVIDIA allegedly "cheating" in Futuremark's 3DMark Vantage benchmark via an offload of PhysX-based physics calculations that were previously sent to the CPU that, with the latest 177.39 driver release, now are sent to GPU for PhysX processing. We have followed them to a tee and this new beta driver has not been submitted for consideration. In terms of 3DMark Vantage, if you’re interested in making a driver change and submitting that, Futuremark's BDP (Bechmark Development Plan) process has strict guidelines you must adhere to.

Optimizing solely for benchmarks is simply not done at NVIDIA. NVIDIA, Taylor: Legitimate optimization are reasonable and important, only if it improves real game play.

HotHardware: In terms of driver development and other product optimization efforts, what is NVIDIA's "official" (or unofficial) stance on optimizing for benchmarks?

GPUs are 5 - 20 times faster than CPUs in physics calculations, depending on the calculations you're speaking of. The new beta driver we released is just a sign of what’s to come. The largest games developer teams in the world are working with PhysX now. NVIDIA acquiring Ageia solved that problem. Ageia's PhysX adoption problems were in general due to a small installed base and developer support. The reason we bought Aegia was to enable our GPUs to provide these sorts of effects. These sort of effects just weren't possible with CPU-based processing, if you wanted reasonable framerates.

We're working with game developers now that are using physics in things like Naval Warfare simulations with scenes where firing broadside on a ship you can use PhysX to enable a full explosion of the ship if you hit it right and watch it blow into thousands of pieces.

High-end physics effects are just VERY cool. Roy Taylor, NVIDIA Corp - Opening comments: NVIDIA acquired Ageia and their PhysX technology simply for the wow factor in games. The following is a quick-take transcript of our discussions with the various parties involved, as well as relevant commentary from a third party (Rein of Epic) that speaks to the core of the allegations and exactly what NVIDIA is or is not doing with their latest driver release. However, when the occasion presented itself to dig into the latest allegations of NVIDIA leveraging optimization cheats in their drivers for their recently announced GPU-PhysX port and 3DMark Vantage, we couldn't resist learning all we could about the rest of the story and sharing it with you.Īs such we jumped on the phone with not only Roy Taylor, Director of Developer Relations and Brian Burke, Senior PR Manager of NVIDIA but also spent some time talking to and trading emails with Oliver Baltuch, President of Futuremark, as well as Mark Rein, Vice President of Epic Games. There just aren't enough hours in the day to go down the proverbial rat-hole all that often. Though HotHardware Management heritage is of Italian descent and thus not shy of taking on a passionate debate, we generally like to stick to the facts, rather than dabble in rumor hearsay or mudslinging. There's no shortage of drama in the Desktop Graphics industry, with bitter rivals NVIDIA and AMD-ATI taking shots at each other at any opportunity.
