LOL, which is why two big 2010 releases like Mafia 2 and Metro 2033 utilize hardware PhysX
And those are just the hardware PhysX titles, and not software.
You don't have a clue..
Also, even though the article makes the case that better optimization would undoubtedly lead to better physX performance on the CPU, it still doesn't mean that the CPU could ever equal the GPU when it comes to processing physics algorithims.
Case in point, there is no software physics game that equals what you can find in hardware physics titles. A title like Mafia 2 features realistic cloth simulation (without the use of scripted animation), as well as advanced particle effects that use tens of thousands of particles for explosions and environmental destruction; far more than a CPU could handle in real time..
The fact is that the GPU will always be superior to the CPU in this regard, regardless of the amount of optimization on behalf of the CPU.
GPUs are naturally suited to that kind of computation, and when you look at it from a cost/performance perspective, the GPU easily takes the number one spot.
