csrss.exe priority

[0ka]

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

i can see more than 10 "tweaking" videos on his channel

He does warn people to do every tweak at their own risk tho.
he shows a genuine desire to learn and test even more by mostly being open to discussion.

Most of his "tweaks" are not dangerous (some are, because he doesn't really test changes), but they are useless for an average computer person (he applied TCP tweaks in some video (networking guide) to increase connections limit and decrease FIN timeout, only server user with thousands TCP connections can benefit from this)

we talked and he said that he wanted to improve, but he wanted me to waste my time watching his videos instead of him asking me something before making a video (I can't help you if you don't help me help you) (sorry for bad english)

sorry for the hate savitarax, you seem like a nice guy outside of tweaking, but nothing has changed on your yt channel since we talked a few months ago

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

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

you still haven't watched the video? https://youtu.be/-jYnDuK-vB0?t=36 (also you can hear his microphone crackling probably because he messed up process priorities)

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!

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)

Seems like using this regkey is the only way to make windows keep up with 8000hz polling. Does rawinput bypass csrss.exe?
