So I downloaded parkcontrol and unparked all my cores. I launched hwinfo64 sensors only, with parkcontrol open, and opened up stalker 2 to test temps. I had steam overlay open to monitor the FPS, CPU, and GPU usage. The CPU usage dropped to 0, GPU went up to %100, the game crashed after like 10 minutes, but I was able to close the window and everything was fine. However, I couldn't revert the changes that this program made. Regardless of the setting on the parkcontrol UI, it won't revert back to normal. My BIOS is up to date (Strix z590 e), speedstep is enabled, turbo boost is on auto, and c-states were enabled. So my system would idle at ~3.5 and boost as necessary.
I've tried so many things to reverse this. First, i tried using your program, but the options were locked in the sense that ticking on or off and changing the percentage just diverted back to whatever it was before the crash. I tried restore to default, powershell commands, system restore, more powershell commands. I'd list them all but the conclusion I've come to is that I have to reset my BIOS back to the factory release version and then reinstall 2302.
I've uninstalled your program, reinstalled it to no affect. The shell commands changed the values but they had no affect on the actual problem. If I change my power plan to balanced and check the performance in task manager it starts throttling but I'm not exactly sure if it's working properly. IN hwinfo the cores are all throttling, but it just seems like there's something competing with how it's supposed to work. I'm just sitting idle and the cores are bouncing up and down. I don't really know.
Bottom line is I want this back to what it was before I installed the program. Any help would be appreciated. I want to use this because the performance increase is huge, but I want to have control over it.

Hmm, the core parking settings shouldn't have affected CPU usage %, so there may be something else going on. I'd closely evaluate the thermal conditions of your system. A properly built system should be able to run a 100% CPU load indefinitely. It's possible that you were so close to the thermal limit before that the simple act of unparking cores caused you to exceed it. Have you run extended stress tests?
Regardless, all changes made by ParkControl to the power plans can be reverted with the "Restore defaults" link shown below the parking settings group. Note that this is only visible for power plans that have a default. Custom power plans you've created won't have any defaults to restore to.
You can similarly reset the power plans and modes in the Windows Power Options. There's nothing else that "sticks" and won't go away.

Oh no no, there's no thermal issue. I can run unparked full throttle no problem, that's why I like this program. It's just that reverting doesn't do anything.Regardless of settings on windows power or your program it will not go back to idling at 3.5 and boosting to 5.2 when needed. I mean it's fine, there's no instability, games running great with higher fps.
The cpu usage thing was just the steam overlay monitor. I think that crash had more to do with the hwinfo constantly polling, also c-states were still on so that might've caused instability, but the fact remains I cannot revert the changes. If I go to the processor min/max settings in the advanced windows options it will not honor those settings either. So your program is still somehow controlling the power setting even after I click "restore defaults" and uninstall it.
It sounds like maybe the CPU frequency scaling min/max attributes. What power plan (or mode) are you in?
What does ParkControl show in that section? The defaults are usually "Freq Scaling" ON and a value of 5%. Is it showing something different?

Using bitsum highest performance. Yes, it defaults freq scaling to %5 but it doesn't honor the change. Changing the min processor performance state in the advanced power options in windows doesn't do anything either. It just does not honor the settings despite them changing on the UI. Unless there's some sort of UI error after uninstalling this program, I mean I don't know. It just will not drop back down to idle at 3.5ghz despite the settings reading that they're back to default both with and without your program installed.
From my experience bitsum highest performance bobs up & down between min & max frequency all on its own when the processor is idle. I guess this is a side effect of performance enhancements being eager rather than lazy.
I would suggest using Park Control & the Switcher option to select bitsum highest performance & Balanced power plans to achieve what you are after (I did).
Hope this helps.
