yeah- well the guy is adding speed-up features now, so he says that the 0.5 release will be faster.

for people like me- who can leave the computer on during school/all day, all night and not having to worry about others wanting the computer, or me getting on (my computer- and im only at home for about 2 hrs anyway on weekdays), I don't want to fork out hundreds or thousands for VRay or Maxwell. So this works for me.
