No I don't mind at all! In fact I'll try downloading it myself. Tomorrow I will reinstall my old AMD 2400+ machine and try to render the same scene with the same settings and time it. If the AMD is faster then it is only utilizing 50% of the CPU. Installing SR3, did however, fix tons of bugs and load times but not the rendering times, at least not noticable. So I hope using CorrectReference does the trick... If HT doesn't on/off doesn't...
