Halving the available amount in prefs made no difference to render times.Perhaps I am wrong, but I thought the idea of "available cores" was to restrict the # of cores that Terragen uses so that remaining cores could be devoted to other uses?No, I believe you are correct.There's a few things to be aware of. In my case, I get 16 cores available if I don't override the core detection in preferences. If I want to render at 50%, I set the maximum threads in the render advanced tab to 8. However, sometimes I need to be careful with the heat, and while setting the max threads to 8 keeps the TG core usage to around 50% during the render, it does not throttle the populating phase when a render starts (so core usage can go to ~100%.) I've had my computer shut down due to heat limits I've set -- not because of the actual rendering, but the population calculation.So, overriding core detection to (in my case) 8, will limit TG usage to ~50%. Of course, added to that will be whatever else your system is doing.
