PhysX on a CPU likely to see very little benefit from SSE recompile

The results speak for themselves. Although there certainly is some performance left on the table by nVidia, it is nowhere near as dramatic as Kanter claimed. In synthetic tests, there is about 8% to be gained from recompiling. This is nowhere near the 2-4x figure that Kanter was using. In fact, 8% faster PhysX processing would mean even less than 8% higher framerates in games, since PhysX is not the only CPU-intensive task in a game. Perhaps the net gain in framerate would be closer to 3-4%, depending on the game. In other words, recompiling PhysX with SSE would not make CPUs threaten GPU physics. Not even close. The difference would be lost in the margin of error, most likely.
