Still check if you have CPU parking off. The ultimate perf plan does not switch it off by default

Interestingly enough, even though mine under the current power plan both set to 100% and after having done the registry edit last night and rebooted... I still have cores parked.

 

wtf

Not the correct settings. The CPU Parking setting is hidden by default

To show it see 

 

But I recommend CPU Unpark.

as stated here, ultimate power plan is hidden but can be enabled by a powershell / command prompt run as admin

I can confirm unparking cores worked for me.  As an FYI - I had previously unparked cores when i setup my PC earlier this year, but was not aware they were subsequently parked later (maybe by a Windows update...not sure).  So I recommend checking periodically...ymmv.

Unparking cores did it. ST everything is fine, under MT terrible stutters with the same graphical settings. Made the regedit change and now its smooth and better than ever so definitely a problem with core parking.

[YoYo]

Has anyone managed to prevent processors from parking on Windows 10 and 13900K? What method worked?

Unfortunately, I have the impression that most of these examples do not work with this processor and there is still a forced parking option here. I tested with the software (UnparkCPU), I tested with the idea from the video for Windows 11 and regedit changes, also with a change in the plan (I had 100% and I have High performance) and I still see processors parked like default. No idea why it dosent work. I instlled new drivers for chipset, BIOS etc yesterday. The same still.

Unparking Cores with the app provided by Adrian is simple and is probably the single biggest "hack" to improve quality of life for DCS I've ever used. There are always discussions about turning this or that on or off and it never makes any observable difference and is likley placebo in most cases. That appears to be not the case here. For the last few months I would get intermittent stutters and large FPS drops they would clear up then come back it was quite annoying. Just got through about an hr of online play with not a single issue. Im pretty sure thats not happens before in recent memory. 

for win 11 running this app should be a requirement before DCS will let you install it.

thanks for the tip.

2nd cmd is different to the first. Ending in 83 is power core. Ending in 84 is e-core. 

PCore: powercfg -attributes 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE 
ECore: powercfg -attributes 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318584 -ATTRIB_HIDE 

Also the setting seems unintuitive to me. 100% means no parking. Zero means allow parking for all cores.  Reading the setting I expected it to be the other way around

Scary how many settings are hidden. But they also generally hidden as you can have issues with some of them if the setting is not fully understood.

I ran these but the settings are still not visible for me.

The setting needs to be set for your active power plan. So you need to repeat the search on the registry for all items until the power settings key

Might be easier to use tool like https://coderbag.com/programming-c/disable-cpu-core-parking-utility 

Note: By default the High Performance power plan should have parking disabled.

Does it should be activate (Apply) only when DCS is running and every time or just one it doesn't matter whether DCS is working or not at the moment? Maybe I was doing something wrong?

Once you press Apply, it is applied to the current power plan. So app can be closed and will not be needed again, unless the power plan changes.

If you reboot and then look Unpark CPU, it should show 100% for the selected power plan. Otherwise the setting has not been applied, for whatever reason

If you on a laptop then settings might have been hidden from the power plan by your manufacturer, or maybe was not run under an admin cmd line. Also max sure it is the high performance plan.

Use a app like CPU Unpark or Park Control. They just setting the value in the registry (which is what the power plan is reading). Note it is for the selected power plan and then if on batcher or plugged in.

In the app, set  parking off. You should not need to reboot but do recommend you switch the active power plan to something else and then back again.

It also seems that CPU parking is not the answer for everyone's stuttering issue.

Default most likely would been 4, for later Intel CPUs. Just move the slider to the left until you see 4 and press apply.

Or just reset the entire power plan. Edit Power Plan, set another power plan active, select the the power plan you want to reset and then 'Restore plan defaults'. Then set that power plan active again

 

 

Did it help with your stuttering / freezing issue?

 

Btw. Also for back to defaut:

command prompt (as admin) and enter: powercfg –restoredefaultschemes

Thanks for this.   It has cured my 2.9 MT issues.  2.8 MT was fine.  

For reference, I have an i9 13900KS. 22 were parked.   2.9 MT (DLSS on or off) was a slideshow.    Ran this app and all are unparked.  Now, 2.9 MT with DLSS, max settings, fps is 200+ and at times hitting my monitor's max refresh of 240 fps (Samsung NEO G9)

I dont know what to do, I dont get my Processurs to stay unparked.

Tried with unpark CPU App

Tried with power plan

Tried running regedit as admin to change the values

 

nullno matter what I do it returns to 0x00000064 (100).

You are not alone ;).

nullThis one seems to work for me. When I first started it, only my E-Cores seemed to were on no-parking.

You you need to set ValueMin to 100% (0x00000064). Provided this is the correct key for P-core parking, which is not evident from your screenshot (should be 0cc5b647-c1df-4637-891a-dec35c318584).

Hmm, on this video it was dec35c318583: https://www.dannymoran.com/windows-cpu-core-parking/ so maybe here I did wrong entry and it doesnt work for me? You are writing about dec35c318584.

[dawgie79]

One should not edit the Windows Registry so lighty.

Better to use to command to make the CPU Power settings visible: "powercfg -attributes 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE" in a Command Prompt which runs as administrator!

Then go to the Power Options (Win+R -> type "control panel" -> Hardware & Sound -> Power Options), change plan settings -> change advanced power settings -> Processor power management -> Processor performance core parking min cores 100%.

Again, one should not edit the registry if it's not needed. And most of the times it's not really needed, often it's a shortcut but in the wrong way.

Do with this what you want.

In fact, disabling the cores parking has changed nothing  for me. Just the statistics are changed. Before it was an issue 4/5 starting DCS and now I can say 2/5. But now, I have the temporary solution found here:

When DCS doesn't start or starts with stutterings: I disable the core 8 and enable it again 30 seconds later.

 

So, the patch from today has changed nothing but disabling-enabling  the core 8 is the only solution waiting that ED fixes the issue.

Mixed bag for me. I ran both of these, but it was the 2nd one that actually let power settings (or QuickCPU app for that matter) properly unpark the cores (Win 10):

My performance issues are intermittent. Some launches, DCS favors my e-cores and tends to load them up more, bringing frame time spikes and stutter along with it. Other launches it doesn't do that so much and the game runs better. 

In any case, the first launch of DCS after properly unparking all cores, it just loaded up my e cores and didn't really produce a positive result. So, it seems the general issue I have with e cores sometimes being preferred over p cores, which also causes my performance issues when they happen, still persists after unparking cores. 

A different game I've been messing about with again lately loads up all of my cores without needing to disable core parking, but said game isn't exactly a benchmark for performance  I did find the core usage to be surprisingly good in said other game, though, without any manual intervention necessary. 

ymmv. 

[Ram69]

Ended up doing a move from win 10 to win 11 last weekend via a completely fresh install onto a new 4TB 990 pro m.2. Frame time spiking is unfortunately way worse in win 11 now. Causing unplayable stutter on instant action runway start in the apache on Marianas. Disabling core parking made zero difference. I'll be back next patch I guess. Tired of messing with it.

If you do not see the "Processor performance core parking min cores" option under "Processor power management" when viewing a power plan, then you can run the following command from an admin command prompt

powercfg -attributes 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE

If you want to hide it again then change the -ATTRIB_HIDE to +ATTRIB_HIDE

100% means no core parking. 

This should be the default for the 'High Performance' power plan, as shown in the image in the post above.

 

 

Followed this instruction with power plan «Ultimate» and all cores gets unparked. Default for me was 4%, increased to 100%.
