Processor Test 2: Physics
This is the last test that impacts the overall score, and it’s designed to represent the load related to physics calculations in future games. It’s another aircraft race, but with gates that are very close together, with each plane (made up of 12 body sections connected via 11 joints) colliding and giving off smoke that dissipates little by little as the environment dictates.
Since AGEIA has joined Futuremark’s paid participation program, this test is optimized for the PhysX PPU found in gaming PCs, which absolutely does not reflect the current situation - nor is it likely to change, unless some big surprises are in store. The PhysX library is used directly. Note that the physics performance of the GPU isn’t tested here (though that would have been logical since the PPU is), but it is measured via the two graphics tests.
Note first of all that this test is a little more dependent on the graphics card, with a gap of up to 7% between an HD 3870 X2 and an HD 3870. For the rest, the spread between results is similar to what it was in the first tests, though a 50% increase in frequency resulted in only a 41% increase in performance here.
