Looks like the CPU is rigged to slow down to a stable speed instead of crashing when it over heats.
Software rendering will max out the CPU to 100% and it will remain like that until the task is done, regardless if it takes hours, or days.
If I use a laptop for software rendering, and I have before while batching rendering hundreds of frames, I flip it upside down while bridging the device by it's edges on some books, to keep it as cool as possible
I bet the Macbook Pro Retina sucks for intensive CPU usage, cause the thing is so thin with shitty ventilation. The processor will have to slow down when it reaches dangerous temperatures, simply because it 100% will when people attempt to do any kind of CPU intensive workloads, such as software rendering or video rendering.
Apple is an overpriced fashion company. When it's time to get serious, use more affordable and advanced hardware instead of being ripped off.
It saves time for both me and the users here when the other option is a giant rant. Would you seriously prefer that I just type it all instead of linking to an external reference that'll do a better job?
With this sort of crowd, unless it's a discussion on the larger more personally analytical side, they're more likely to actually see what I'm meaning to say this way. On top of that, the use of references gives me slightly more credibility than just saying it myself.
At least the things I post tend to carry actual content that people can think about.
