Attached Link: Thread Priorities are Evil

> Quote - I have found all live previews (with auto update checked), without exception, can slow things down to an annoying level. Things will freeze as it tries to update. I'm not saying they are not handy, because they are a nice tool to have...but I have always found myself unchecking any auto-update or giving it the lowest priority level. Please tell me this feature has user definable levels of priority???

There are no priority selections at this point, since unfortunately thread prioirities do not behave the way we would like them to behave. For the technical details, see the link, or if you just want the money quote: "Set up your threads at normal priority and let the operating system deal with scheduling them. No matter how brilliant a programmer you may be, I can practically guarantee you won't be able to outsmart the programmers who wrote the scheduler in your operating system."
