csrss.exe priority

[luxupra]

Hello, is there any benefit from applying a realtime priority to csrss.exe? I've heard it manages the mouse and keyboard input but I wanted to know more opinions on this. Thanks!

My system crashes when using realtime mode after unclocking it with windowsD and system informer, so I wouldn't recommend it.
But here is a video how to do it if you want to experiment:

try both and pick what your prefer, my system work good with realtime, but mid-tier and sloppy systems maybe better with high priority, anyway is better then default.

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\csrss.exe]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\csrss.exe\PerfOptions]
"CpuPriorityClass"=dword:00000003
"IoPriority"=dword:00000003

CpuPriorityClass -> 4 - realtime
CpuPriorityClass -> 3 - high

also, DWM work with CSRSS for mouse input (dwm is high by def)

So should DWM be a high priority as well, cause I believe that is just for the desktop and not for games. I have good results by setting asside DWM to my ecores and getting it out of my pcores since those are reserved for games. I could be wrong of course please let me know thanks!

Has anyone had any positive impact by adjusting IO priority? I haven't touched it.

Also you're saying to adjust DWM.exe too? Whenever I've adjusted that or even touched it, bad things happen.

There is no benefit unless you run games/apps at realtime priority (just don't or you will have issues). Both csrss and dwm have high priority by default so your input will be fine unless you set something else to realtime priority (high/lower priority is fine because it's the same/lower priority). Realtime priority doesn't mean literally realtime, it's just another level of process priority, nothing (processes) has it by default.

I actually know savitarax and really don't like his videos because his goal is quantity over quality, he knows very little about what he is talking about and gives a lot of bad advice. In short he made this video because i told him about csrss priority, wind, etc... see description for proof

anyway is better then default.

your reg file doesn't work, watch the video above and find out why. Also i made a video some time ago about Image File Execution Options
https://www.youtube.com/watch?v=UXyTntBu_UM (read description)

tldr: IFEO priority doesn't even work for paint, don't expect it to work on something else, it works very rarely

...his goal is quantity over quality,...

That's an odd thing to say since he's not a frequent uploader.

...he knows very little about what he is talking about and gives a lot of bad advice.

He does warn people to do every tweak at their own risk tho, and also it's obvious his knowledge is above average + he shows a genuine desire to learn and test even more by mostly being open to discussion.
