Open empty scene, press control+sphere and press "D" 5 times. If your system will not hang up, set the strength to 1% and try to sculpt. On 2.66 Dual Core modo 103 gives about one lamp per second.
On the same system with the same sphere (exported & imported via obj) Hexagon works in real time and gives smooth result even in dots mode. Without additional smoothing. In free hand mode you will see blue line only if you will move your mouse very, very fast.
That's the matter of fact and not some sweet dreams caused by watching good picture.

So modo 301 must be 100 times faster than 103 to be close to Hex, not even ZBR.
