If PhysX is enabled, I don't think PhysX games do very well without dedicated hardware. I was unaware the Intel iGPU was supported in this capacity.
Yep, PhysX falls back to the CPU if no supported GPU is present. It's in nVidia's best interests to have it run best on their hardware, so I doubt things will get better in the future with CPU-driven PhysX.--KI6RIT
