3DMark Vantage’s built-in physics test (CPU test 2) uses the PhysX API for physics simulations. Without GPU physics, the test can only run 17 physics operations per second. With NVIDIA PhysX enabled, the physics simulation runs 7.5x faster, at 127 operations per second.
The physics speedup contributes to the final CPU score, which carries a 25% weight on the final 3DMark score at Performance Preset. The physics speedup ultimately translates into a 12.6% improvement in 3DMark Vantage performance.
