I have been reading about "core parking" being impossible to turn off in Windows 10.
The problem with this, is in high end gaming rigs, core parking tends to have too much hysteresis in situations where the system goes to 100% load often. As the load shifts within a high res 3d game for instance
many systems have poorer gaming performance with core parking on than they do with it off. In some cases the difference is surprisingly large as it varies with different combinations of hardware.
According to my understanding of Microsoft's explanation of how it manages power for the cpu, is it uses information from the chip itself to determine what profile to use for each power management property.
This is described here Processor power management options - Windows 10 hardware dev
Microsoft is getting increasingly aggravating with trying to get me to switch from windows 7 to 10. Eventually I am going to be forced to upgrade my win 7 to win 10
Some gaming rigs are experiencing performance issues after switching from windows 7 to windows 10. I think this is due to the configuration of the power management system which the OS is setting up based on instructions from the chip.
I have a wonderful Intel 2600K and eventually I am going to get forced into win 10. I really do not want to take a huge performance hit because the power management system decides to turn off too many cores, and then waits too long to decide to wake them up. (the situation in windows 7 was this problem, thankfully it was able to be turned off)
I am hoping Intel can issue everyone patches for their Intel processors that would set up a maximum performance profile for Windows 10. It could be a special "Gaming profile"
According to the microsoft article linked above, there are about 16 parameters that can be set, and almost that many again for each core.
What Gamer's need are some updates from Intel for their cpu settings instructions that tell Windows this rig has a need for speed and core parking is deactivated. Or at least keeps a minimum of 50% of the cores active at all times. Something needs done that prevents this "power saving feature" from significant lowering a gaming system's overall performance. Right now, it appears it does significantly reduce performance in many gaming systems.
