There are statements from both NVIDIA and the developer that they are not using any NVIDIA GPU specific PhysX features in Project CARS. So, given those two public statements, I would tend to take their word for it over the word of an anonymous poster on a website. Looking at the data, yes AMD is slower. That doesn't necessarily indicate it was done intentionally which is where I take issue with your statement. AMD and NVIDIA GPUs handle workloads differently and both have strengths and weaknesses. There are cases where AMD out performed NVIDIA - I believe this was the case with Far Cry 4 on release, and that was a GameWorks game. I don't believe that the developer intentionally crippled AMD performance.You do realize Reddit was the one who found the 970 GTX only being 3.5GB? If we didn't listen to the reddit poster we would of never caught Nvidia in a lie?
