Legit Reviews talk with Futuremark and NVIDIA about the cheating claims and try to figure out if anything is being done that shouldn't be.

When Futuremark Vantage was designed the AGEIA PhysX SDK was used and a discrete Physical Processing Unit was needed to offload the benchmark DLLs from the CPU to the PPU. We showed this in our article about 3DMark Vantage the day the benchmark came out. We dedicated an entire page to offloading PhysX to a PPU and no one cried that it was cheating moving the DLLs from the CPU to the PPU. Now that NVIDIA had moved the workloads from the CPU to the GPU they are accused of cheating!
