Minimum Processor State vs Preview Frame Rate?

Greetings, all..

I just made an interesting find and quite by accident...

I had been tweaking the overclock on my new build and somewhere down the line I set the minimum processor state to 0% (probably for heat management purposes) (Control Panel > Power Options > change plan settings > change advanced power settings > Processor power management <expand> Minimum processor state > setting)

Background: I noticed that my preview playback rate on raw 1080p 60fps GoPro files was at about 2-5 fps in Best/full or Preview/half (or just about any setting). It had previously been 59.94 pretty much all the time in Best/Full. On a lark, I recalled that I changed the minimum processor state to 0 (from 100) in Windows Control Panel Power Options.

I changed the minimum processor state back to 100% and, poof, full rate preview playback rate!!

So. If some of you kind folks can verify this, that would be quite handy to know...

Cheers and whotnot..

My [I]minimum processor state[/I] was at 100% but I lowered it to zero and previewed some 4K files. The numbers I observed seemed to be within the variation that I observed before the change. It might have declined a digit but it sucked before and after at 11-16 fps on my System 2.

I've encountered this behaviour before. Not sure if I mentioned it here though... An easy way to change it is to set the power plan to High Performance.

I have actually discovered a lot of software that is significantly affected by this, two that come to mind are the Minecraft Server and Milestone XProtect's Smart Search.
