Mostly because the vast majority of Evga members are noobs. Then theres the fact that Evga worked for/with Nvidia exclusively prior to the release of Nehalem architecture, so, the Evga scores section and Vantage runs stood to gain the most positive review by using the physx drivers. This makes the Nvidia cards appear to stand out against ATI cards.
The reason NVIDIA is upset about the cheating claims is because they didn't do anything other than allow the workload to run on the GPU. The way 3DMark Vantage runs the benchmark remains the same as if a dedicated PPU was installed (adding more worlds to the workload). With parallel computing headed to the GPU it only makes sense that benchmarks take this into account. The problem here it seems is that NVIDIA came out with the drivers before the industry had the benchmarks ready. 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!
On the world stage, true overclockers have recognized this shortfall and disparity and when comparing true gpu performance, overclockers agree that to truly compare ATI/Nvidia, you must disable the physx drivers in the Nvidia control panel.
The only enthusiast forum you will see a majority of Physx used drivers when posting benchmarks is EVGA. But, even EVGA staff, moderators and Enthusiasts have agreed it is an un-realistic comparison when using physx drivers.
Hwbot.org is the largest world database for overclocking and is currently the reigning authority on hardware performance information. Physx drivers benchmark submissions are rejected at Hwbot.org.
Furthermore, Futuremark, the maker of 3dmarkVantage, will not list your score as valid if you use the physx drivers as they have also recognized this offloading and bypassing of the cpu onto gpu. Vince a.k.a. K|ngp|n, the current 3dmark world record holder does not use physx drivers and if he did, futuremark would invalidate his submissions to the ORB.
Physx in some cases can be a great performance boost for some games and I applaud its purpose in gaming but when it comes down to which GPU actually performs flatout best, physx use is not permissible in the equation.
If I've missed some points here guys, feel free to chime in. You know I'm still a Noob4Life baby
