Video rendering time dramatically increases when PC is idle?

    Hey guys,

    I have been doing video editing/rendering since I owned Pinnacle Studio back in 2004. I run a project studio out of my home, and just recently upgraded to the AMD Threadripper 1950x.

    In Vegas Pro 14 for video editing, I noticed that a full 2 hour video with video and audio plugins active through out the project, crossfades, color grading, ect took just an hour and a half to two hours to render down when I was at my computer and actively doing other small tasks while it was rendering. I have even assigned Vegas to run on limited cores to do other things like gaming and what not while it renders, with still having solid rendering times.

    Last night, I started a simple 2 hour video render much like my other video that only took a couple hours. It said the render would take approx. 1:45 mins or so to complete, which was about the norm. So I put the computer in lock mode (password required to come out of it - I don't like leaving it open for others in the house to mess with), turned off my screen, and went to bed. Woke up, and it had been rendering all night. 8 plus hours plus had elapsed, and it claimed another 3 to 4 hours was needed to complete the task. I found that very odd, as I rendered a similar video the day before in only a couple hours.

    While I was on the computer seeing this horrific rendering time, I started doing other little things like checking my e-mail, hitting a couple websites, ect. Not only did the rendering time drop significantly from 8 hours left to less then 35 minuets, the next I knew when I was checking a couple websites out, I here the audio notification that the render had completed.

    So, by putting my computer in lock mode, it seems to be drastically slowing down my renders. I was wondering what could be causing this? In my power settings, which are currently set to balanced, I have it set so my system never goes into sleep mode, and my screen never goes to sleep. I have to physically turn the monitor off for it to go into any kind of power stage.

    Are there other settings I need to look at so when I go into lock mode my processor/renders does not slow down? Or if my system is idle it doesn't slow down? I am not even sure if lock mode has anything to do with it. My render times may increase if my pc is idle for all I know. I am usually sitting at it doing other tasks while rendering, so I am not sure.

    Thanks in advance for any replies/thoughts on this!
