Default Re: PhysX officially sucks.

Still, it does have potential, but it without support from ATI and with 8-12 core CPU's on the horizon what's really the point with offloading from the CPU?

Now, if Intel/AMD add extensions to all those cores which could support it directly, that would be spectacular.

Does anyone remember adding an FPU math coprocessor to their system? What ever happened to those? "They actually did give lots of DOS games a boost in FPS".
That's not necessarily true about improving performance because it actually does in my mind-set. You're gaining more performance when compared to the CPU -- so to say any time it is implemented - don't agree.

If the context is does GPU Physics take a performance hit when compared to no added advanced Physics? Then yes. But the point of GPU physics is to allow more advanced
Physic content considering the raw potential of stream processing when compared to the CPU.

PhysX/Apex is more than just GPU Physics but a Physic engine and tool set that is cross platform that caters to the CPU and GPU.
