Physx to GPU or CPU(Nvidia control panel)

My GPU is GTX 950M with 4GB dedicated VRAM and the CPU is i7-6700HQ with 2,6ghz up to 3,5ghz. Which is best to choose for games,GPU or CPU?

Why?I mean,the reason

GPU is always the better choice for physics calculations.

The reason pls? :D

If your card supports it it means it already has the hardware optimized and specialized for it. Physx is an nVidia specific piece of tech. Not every card supports it. But most do. Really unless the gap between your vid card and cpu is that vast, its always better to run physx off the GPU.

I think your reason is just *barely* satisfying.

PhysX relies on CUDA core units dedicated to processing the physics calculation. Your GPU usually have hundreds of these CUDA cores if not thousands while your CPU's GPU is much more modest. They don't exactly have CUDA cores for starter, but they attempt to imitate the role of these.

PhysX is an old startup which have been bought later on by Nvidia and sort of incorporated their processors as CUDA cores to their GPUs.

Explanation with numbers here :

Simply put, the bigger the numbers, the better, FLOPS especially, that describes the ability of the Processors to... process operations (notice there are commas and dots, the 950M is better).

More cores... more abilty to parallelize the physics dynamic which is the point of PhysX, calculating the dynamics of shards & pixels of matter.
