I am seeing something I didn't get with any other version until now. Some actions, like resetting TG (file menu > New) or loading and saving scene files takes 30 seconds, sometimes even longer. During that time TG is unresponsive or draws a blank white window... It's not happening always, but quite often. For example, saving a file (network or locally, doesn't matter) will sometimes happen immediately, other times it takes somewhere between 30-60 seconds. Sometimes, changing values in a node will behave similar and causes TG to get unresponsive for some time. All this is without RTP being used.
When rendering, I sometimes can't access other programs and the mouse pointer disappears or freezes, browsing the internet (Opera, Chrome based) is also heavily affected, the browser hangs or takes really long to load even a simple page.
I suspect that the updated threading and CPU utilization isn't as smooth as it should be. I've seen similar behavior from renderers in WIP stage where CPU threading hasn't been optimized. I never had these problems before and could perfectly render in the background and still do something else on the same PC.
Anyone else seeing this?
