Re: Haswell iGPU will equal GT 650M performance

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.

You might be right. It's probably the CPU portion that handles it.

Either way, games with PhysX absolutely need a dedicated GPU.

I couldn't imagine how bad it would have run if I was using the onboard HD4000 graphics.

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.
