I am doing a bunch of rendering locally and when I switch to another window while rendering, the amount of processing dedicated to rendering is reduce due to Focus Theft as described here. If would be nice if there was a way to prevent this from happening so that during renders that take a while (they take a while...?) I can work on other things/write emails etc. Not sure how to do this or if it can be easily done but with only a single computer, this would lead to massive productivity gains and reduced rendering time.
