The rather sensational headline above says it all.

Direct Link:

And a snip:

“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. Nothing within the benchmark is changed at all. No software libraries or even a line of code changes in the benchmark whatsoever. The only thing that changes is that installer, nothing else. It has been said that the tests results look different on the screen when running with PhysX enabled on the GPU. 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. This isn't a graphics test; it's a physics test. 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 is by design in the benchmark and if the folks accusing us took the time to run it, they would know that.”
