Nvidia accused of cheating again
"Tut tut Nvidia"
Nvidia cheats on 3DMark with 177.39 drivers
While Nvidia and ATI have both been accused of 'diddling the books' where drivers are concerned, Nvidia appears to have made the practice a mandate. According to our source, Nvidia is violating FutureMark rules with their latest PhysX drivers. Now how Nvidia are doing this requires a little background information:
3DMark Vantage has four major components, two CPU and two GPU. One of the CPU subtests is a physics-based test. The physics test is based on the Ageia PhysX API, a fairly widespread API in use by a large number of games. Between the time that 3DMark Vantage development was started and the time it was released, Nvidia bought Ageia.
The problem is that the PhysX DLLs, and for that matter, the whole API is now owned by Nvidia. In and of itself, this is not a problem, especially if the company involved had a history of honesty, integrity, and fair play. Nvidia has none of these attributes, and has a proven history of cheating on 3DMark.
So, with the latest driver, Forceware 177.39 drivers, Nvidia put its now in-house PhysX APIs into the drivers. Instead of it running on the CPU or on the PhysX chip, it is running it on the GPU. It owns the GPU and it's drivers along with the physics API and all those drivers. This is a dangerous situation.
Because of what Nvidia has been accused of, it has now created quite a dilemma: the current 177.39 drivers may not be legal for 3DMark and preclude the user from attaining a valid score; and it essentially means that it isn't even running the same program as others who run 3DMark.
If running the 177.39 drivers, the end result means about a 10% increase in scores, and a claimed 7.5x advantage on the physics subtest.
Tut tut Nvidia if this is proven to be true!
