PhysX is over ten years old now, and back then running PhysX supported games with cpu-only PhysX setting guaranteed low framerates.

Can today's fastest processors like Intel i9 paired with non-nvidia GPU run those old games with cpu-only PhysX setting with good FPS?

Are there modern CPU benchmarks with old PhysX games?

    I think the question here is: can contemporary CPUs on systems without dedicated GPUs run older games with PhysX enabled (and presumably smoothly)?

If you watch PhysX CPU vs GPU vs GPU PhysX then you'll see that PhysX on CPU is still abysmal even just 4 years ago reducing framerate 50-90% less than just running it on the GPU itself. Most games don't even support PhysX on CPU anyways.

Maybe if you had a particularly bad GPU like the GT 1030 or something then CPU PhysX might outperform it but you'd be a fool to pair a GT 1030 with a CPU that can run PhysX better than it can.

If you're trying to achieve PhysX while using a high-end GPU like the AMD 7900 XT then then GPU will always be waiting for the CPU PhysX to catch up and you'd be throwing performance out the window.
