Nicolas, I'm running a machine with a Pentium 4 HT CPU. My (limited) understanding is that hyper threading is not really two CPUs, but can give a performance boost in some circumstances. Can you say if the new Chaoscope will do so? The windows task manager can display CPU usage as two processors and the current Chaoscope appears to only use only (mostly?) one during rendering. Also waiting for the release in eager anticipation.

Of course Chaoscope detects the number of available cores or CPUs and uses the standard single threaded render on single core CPUs. ... ___________________________________________________________ Yahoo!
