Disabling security mitigation to stop jitter

[JohnR]

I've been lurking for a while trying different things. Disabling hyperthreading definitely really helped the smoothness and consistency of my input lag but there was still always a difference. Sometimes my games ran well and sometimes they didn't. What I tried over a month ago was disabling Control Flow Guard through the windows exploit protection settings on a per game basis and for dwm.

Basically disabling spectre and meltdown and all the process mitigations in windows performed worse for me but only disabling Control Flow Guard in the windows options for dwm.exe and whatever games i was playing basically eliminated all feelings of jitter and input lag. Apex has been running flawlessly now for over a month. Idk if this will help everyone but maybe it will help you.

i used InSpectre to disable Spectre
seems to work, played for 3h in local servers retakes

i got lags that can be describe as: the time length that takes for animation of actions in the game, is always changing
someone peek ,aim ,dock and such takes like 0.2 second while im not able to move/aim even a bit

next day: doesnt seems to stick
im gonna try install new os and also disable cfg and see

Yes, it works. Checked for win11 25324. The mouse has become even sharper and faster. The first few matches I could not aim at opponents. The sensitivity seemed to be very high. In addition to this tweak, I use 30 more different improvements, such as dwm priorities, csrss and others, BIOS settings, including hidden ones.. My mouse responsiveness is better than any pro player.

It's better to try different solutions to a problem rather than claiming magic electricity is making it impossible to play games and try nothing.

I'm on intel 11th gen and using inspectre made my performance worse fps wise and stuff was just not smooth. I think only the older intel CPU's benefit from disabling spectre mitigations. AMD cpu's get worse performance too. The only way I get benefits from disabling security stuff was using windows exploit protection settings to disable Control Flow Guard for dwm.exe and whatever game .exe I have been playing.

Watch it -- this is your pre-ban warning.

People need to make their posts more descriptive - like Disable Spectre/Meltdown to mitigate jitter.

Yes, it used to help, on newer systems it actually hurts performance though. There are a couple articles about this. YMMV, but in my experience it made things worse disabling it now. I used to have it disabled.

Here is something showing the opposite, I can't find the Windows article that I was basing that off of.

There are also some microcode updates that you had to not install (IE don't update your motherboard firmware) and if they're installed, you can't undo that. However with newer processors they're already built in. Complicated issue, but easiest way to mess around with it is inSpectre.

I said disabling spectre made things worse. I found ONLY disabling Control Flow Guard per application and with dwm.exe worked best.

Problem with this article its testing under Linux conditions; which might differ in Windows environment.

This article is looking at the current performance costs under Linux with the default mitigations and then the run-time disabling of the relevant mitigations for each of the processors under test while using an up-to-date Ubuntu 20.10 paired with the new Linux 5.10 LTS kernel.
