Tweaks 2024 Edition.
The main stuff is in PURPLE, the other stuff is optional.

First check the
"Unofficial Windows 10 and 11 Audio Workstation build and tweak guide"
by Pete Brown.
https://devblogs.microsoft.com/windows- ... de-part-1/

My version is more hardcore...
That is why you must first Create System Restore Point!
https://www.elevenforum.com/t/create-sy ... s-11.3602/

To check for Windows DPC Latency use
https://www.resplendence.com/latencymon
or the more precise Microsoft Xperf.

- The first step is to check/fix the File System and Operational System Integrity
Run this as admin https://www.mediafire.com/file/5yqx79cn ... S.zip/file
it is from Windows 11 Tweaks, Fixes and Modifications [Overview].

- Disable Windows Hibernate
https://www.elevenforum.com/t/enable-or ... s-11.1894/

- Disable Core Isolation and Memory Integrity. (Use the registry)
https://www.elevenforum.com/t/enable-or ... s-11.4942/
Attention, Core Isolation is a security feature!
Modern CPU + updated drivers + Latest Windows 11 the performance hit
of this feature should be very small.
IF you are using AMD 7900X3D/7950X3D do not disable!
It is needed for this https://hwbusters.com/cpu/amd-ryzen-9-7 ... olution/3/
But there are two solutions, this or use Process Lasso CPU Affinity and set/limit
all background process to the non 3D-cache cores, leaving the 3D-cache
cores for the application that may benefit from it or vice-versa.
In the 7900X3D the non 3D-cache is the Core 12 to 23.
In the 7950X3D the non 3D-cache is the Core 16 to 31.

- Disable Core Parking
https://bitsum.com/parkcontrol/
If you are using AMD 7900X3D/7950X3D it is the same problem mentioned
above, else if you use Process Lasso.

- How to Activate/Enable the Ultimate Performance Mode Power Plan.
In the Command Prompt or PowerShell window, copy the command provided below.
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
If you are using AMD 7900X3D/7950X3D you must keep it in Balanced.
It's the same problem you saw above, the solution is Process Lasso.

- Disable Widgets
https://www.elevenforum.com/t/enable-or ... s-11.1196/
or uninstall
https://www.thewindowsclub.com/how-to-u ... windows-11

- Disable Microsoft Edge from running in background

- Set the Windows Priority Separation to 26hex
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl]
"Win32PrioritySeparation"=dword:00000026
https://www.thewindowsclub.com/processo ... indows-7-8
Or double click the REG file https://www.mediafire.com/file/1svbqo0j ... 6.REG/file or


- Set the active power scheme to Processor performance time check interval = 5000
(Click in the image to download the Windows power plan settings explorer utility)

If want the details, look at
https://youtu.be/n9xAG3nb9XQ
Also deselect "Processor idle demote/promote threshold"
and set the AC value = 100 for BOTH "Processor idle demote/promote threshold"


- Disable USB selective suspend setting and PCI Express Link State Power Management.


- Disable Energy/GREEN/Power stuff for both Realtek and Intel LAN


- Go to Settings>Personalization>Colors = Disable Transparency Effects


- Go to Settings>System>Multitasking = Disable Snap Windows


- For the drives(SSD/HD) enable the
"Turn off Windows write-cache buffer flushing on the device"
Step 1. Press Win + R to open the Run dialog.
Step 2. Type devmgmt.msc and hit Enter to launch Device Manager.
Step 3. Expand Disk drives and right-click on the disk drive you want to enable/disable disk write caching to choose Properties. Here, we select an internal storage drive.
Step 4. Under the Policies tab, choose from "Enable write caching on the device" and "Turn off Windows write-cache buffer flushing on the device".


- Enable MSI(Message Signaled-Based Interrupts) with this utility.
You can not enable MSI for USB 2, FireWire and some WiFi, but it is a must for the GPU.
https://forums.guru3d.com/threads/windo ... ol.378044/


- Set the GPU/LAN/USB(mouse/audio) DRIVER to use a different CPU CORE/E-CORE.
Microsoft Interrupt Affinity Tool
Here(AMD 5600X 12 CORES) I set the GPU to use the last 2 cores.
Because of hyperthreading/SMT each 2 cores = 1 real core.
Intel E-core does not have hyperthreading yet.
GPU driver = 11 and 10
USB xHCI Host = 9 and 8 (There may be more than one, set it to use other cores)
LAN driver = 7 and 6

- For AMD GPU we can install the driver only and to install without any bloatware, check here.

IF you play games better do the Full Install, but can delete/uninstall AMD Crash Defender/amdfendr/amdfendrmgr and deselect

For Nvidia you have the option to install a less bloated driver from
https://forums.guru3d.com/threads/546-2 ... on.433367/
Do not install Nvidia Shadowplay!

And set "Power management mode" from Adaptive to Maximum Performance.
https://nvidia.custhelp.com/app/answers ... erformance

Sometimes it is beneficial for ANY GPU to disable MPO(Multi-plane overlay).
Disabling MPO can improve some desktop apps flicker or stutter issues.
But disable only if after all teaks you still have high GPU latency.

- Disable Threaded DPCs(Windows XP behavior).
This raises the priority of all DPCs to DISPATCH level, which is generally the
highest priority level that drivers work at and it prevents DPCs from being
blocked by the kernel, user software, page faults and asynchronous procedures.
It can have a positive or negative impact on performance, depending on the
hardware and software characteristics of the PC. YMWV!

The best thermal "paste".
https://youtu.be/brNqruM2RfM
Upsiren PCM-1/Honeywell PTM7950/Thermalright Heilos is a long lifespan PCM thermal material.
They are the same stuff, but sold with different names, thickness and sizes.
The PCM(phase change) thermal compound is a plastic(polymer) that melts, no oil to
evaporate/dry and longer molecular chain making it more resistant to pump out.

It is also sold in the form of a paste(polymer+solvent), the PTM7958 is an
improved version of the paste used by Lenovo. The paste need
some time for the solvent to evaporate before mounting the cooler.
PCM needs minimal pressure to work properly or the performance will not
be better than regular thermal paste, which is why some users do not see
better performance with PCM.
One example here of an Intel CPU without the Thermalright Contact Frame.
The CPU is bent and the pressure is only good in the center.
For uneven surfaces like the bent/warped Intel example, the Shin-Etsu X-23-8117
probably is the best.

Minimum sizes for the pad:

- 30x40mm for Intel (LGA 1700)
- 40x40mm for AMD (AM4/AM5)

Very helpful tips here @Pictus, even for people who aren't doing music on their PCs. The tips on reducing the AMD and NVidia driver bloat are great, and you've probably noted this on a previous page (my apologies if so), but wouldn't someone have to go through all the tips again with each update of the driver? AMD and NVidia sometimes update drivers within a week or two of a previous version when they find a particularly troublesome bug. As much as I might want to keep their bloatware off my machine (and those of my clients), I wouldn't want to have to spend 20 to 30 minutes every other week doing that, just to chase down their bloat.

Of course, you didn't create the problem, and I'm thankful for what you've posted here. But I know that when I've de-bloated both in the past, I'd have to do it again after each update. AMD and NVidia would simply re-populate the Registry and the items in Device Manager.

I know there are ways of "automating" some of this, and/or storing Registry values (or setting up Group Policies) after you've cleaned up the PC and then loading those .reg files back into the Registry, effectively making the changes for you. But these work-arounds could also make things.

And FWIW, I think it's kind of ironic that the video card manufacturers bloat their drivers with the same kind of junk that could affect game play or the efficiency of the card itself. Sure, some of it looks nice, but hardcore gamers are probably more concerned about frame rates than the transparency effects of the driver GUI.

Not all tweaks, I guess the latest NVIDIA has MSI enabled by default, so just
the Microsoft Interrupt Affinity Tool and the AMD GPU steps and I guess
the Nvidia Power management mode.

Well...
I tested Gfrad to install a totally debloated AMD driver, probably it will
work for Nvidia too.

Is it no longer recommended to disable unneeded services in Windows 11?

[chk071]

Is it no longer recommended to disable unneeded services in Windows 11?

I think that's always recommended.

I never do it , but, the less you have running, the better the performance.

I think that's always recommended.

I never do it , but, the less you have running, the better the performance.

I read that Win 10/11 does a better job with only loading and running services "as-needed", so that disabling them doesn't matter so much. Not sure exactly whether this is true.
