kernel tweaks, updated May 16

[Slender]

day to day update

I'm done for the time being. Another thing I did to improve latency was unlock csrss and dwm because changing their priority didn't work correctly. Now I have 2x csrss and dwm assigned to a single core, running csrss at realtime and dwm at low. Also put 2x fontdrvhost on a single core at low priority and audiodg on a separate core without changing its priority. If someone doesn't know these can be changed in the details tab of task manager or Process Hacker, Explorer or Lasso. Unlocking csrss and dwm is done by installing wind64, opening cmd and putting in the command wind64 /d "process id". After unlocking them, I recommend deleting wind64 as it blocks games from opening and also adds input lag.

that all not need in w11 anymore

Feedback time for some of the added tweaks (disclaimer: I'm mainly focusing on input delay and feel).
HypervisorEnforcedCodeIntegrity - Enabled - 0 = increases my input delay.
"SizeReqBuf" 95268 = a bit smoother but with minute increase in input delay I prefer to run without this one.
deleting : PagedPoolQouta & NonPagedPoolQouta = increased my input delay by a lot (I set mine to 0) *I think you also removed these tweaks*
"SystemResponsiveness" - dword:00000064 = increased my input delay (I have better input with this to 0)

for DirectX and DXGKrnl tweaks, I have been running the same tweaks even before, we chose the same ones to add lol.
for Power tweaks, input delay is a bit better but I'm still evaluating, overall pretty nice

Hey, I can't see these registry PagedPoolQouta & NonPagedPoolQouta.

I checked HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management but it wasn't there, so I can delete them. Perhaps I haven't made all the "updates" of this post, so it's missing? Can you check it's Registry Path? Thanks.

It's supposed to be here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management, just re-create them with value of 0 for both if they're missing, those 2 tweaks were previously included here suggesting to delete them so maybe that's why it's missing for your system.

Not sure if you have to do all of this, but I'm running csrss @realtime just fine, while I run dwm on idle. On my end I can definitely feel running dwm on idle vs low hence why.

Check if if they really do run at realtime and idle with the "wmic process list brief" command. If the priority of csrss is 24 and dwm is shown to be 4 then they really do run at their set priorities. But in Windows 10 they have to be unlocked with wind64 and rechecked to actually run like that.

Wind64 Installing Failed to initialize driver :/

dude wth, stop throwing unexplained, random stuff at ppl

I'll allow the post.
Blur Busters tweakers love this stuff.
Some of the settings may work, but others may make things worse.
However, I've inserted appropriate disclamers.

Any experienced forum members should follow up and post findings of the most-effective settings or two, it's often a needle-in-haystack factor in the mix of placebos and non-placebos.

Technical users with lots of time for researching -- should try the "binary search" method if you're testing a disposable/rollabackable operating system install. Essentially, test half of the settings at a time, in a ever-smaller-slice manner (halves, quarters, eighths, and so on, until monotonic) to determine the holy-grail settings. RTSS frametime graphs and/or LDAT-style graphs is good for science too.

Added some, changed some. There are still things I could share but I'd need to write a whole guide then.

Another question man (sorry for my english) i just entered all the commands via cmd like 1 week ago. What i have to do if i want now enter ur "edited" commands and adding some others? Arent they duplicated or something like that? hope u understood what i mean

You can add them as many times as you like, only the values will change. I changed most, so you can even compare them with your current registry values.

Hi, where are the values from the 30th of April update? Those worked best for me. Cheers

Did you find these settings by any chance? I didnt felt good like those settings with updated ones.

No, unfortunately I never saved any of them, just changed along the way. With other optimizations these values give the lowest latency while retaining performance and normal internet connectivitiy. Some of them can mess those up.
