I wonder if MRay hangs your mouse, too.

Now I'm getting tempted to drop VRay and return to the MR fold! Killer feature, I hope VRay integrate it...

Then you can brows the web or what have you while max renders.

i dont agree. Its not buggy at all (doesnt crash anything) and its more efficient than losing an entire core

Why? this works perfectly with vray aswell. Even better in my experience.

Ultimately it's no different then putting it on a lower priority, just more stable and effective... unless you have a low core count like an i3.

Unfortunatly you are a bit misunderstanding the meaning of changing the priority.

Let me say it in this way: You have Ten fingers. You simply tell your Brain that it has not go for such a strong focus on doing one thing your "pottery" for egsample. You tell him, that when you are thirsty or hungry - go for it! But all of these tasks are as done as fast as usual - just the Order, e.g. the "order of allowness" is just changed. (sorry my bad english =) This means when nothing different is anyway to do, even when the "do your Pottery" Task is set to the lowest Priority, your Fingers will do this one thing as fast as it can - not slower and not faster. Cpu´s like i3, i5, i7 .. it doesnt matter - they will everytime do what the have been made for. Not faster and not slower.

BUT WHEN YOU: Cut off one of your fingers, and make sure that this one is moving your courser, changing your windows etc... etc... or just remember the Pottery example - will you be able to do this then in the same Time? ... One finger less?

Changing the Priority will never harm the renderperformance in itself, as far as you leave the machine alone. ANd btw: moving the mouse or things like that - your CPU will switch so damned fast between task - you will never miss something.

Maybe it helped a bit to explain the feature: "Changing the Priority" ..

In max 2014, the mental ray threads come out-of-the-box with "Below Normal" priority for a foreground max, and even one notch lower for backburner threads. This is all settable (from an .ini file) of course.
