useplatformtick and/or disabledynamictick on mouse input lag

Post by nax_dv » 19 May 2021, 15:53

I've read dozens of threads that go many pages long that all have conflicting opinions to this day.

Some say useplatformtick and getting a flat 1.0 or 0.5ms for your windows resolution timer significantly helps the responsiveness and feel of your mouse.

Some say the opposite and that it only increases the input lag and interrupts on your system, and that these timers are used for "debugging" purposes only. I would think by 2021, there would be a definitive answer with concrete science and testing behind it. I was hoping battlenonsense would cover this topic, but i'm not quite sure if he will. I wish a Microsoft/Windows10/Game engineer would be able to clarify too what exactly these do and how it affects the system, the game you play, and your mouse.

Does anyone have happen to know the answer and provide it with concrete science while breaking it down so a layman can understand it?

Thanks!

bcdedit /useplatformclock true make my whole system stutter, like literally stutter. My Explorer and everything slowed down and i have only 30 FPS in all games but some users made other expierences and told that is boosting there system so i think it depends on the current motherboard and cpu.

bcdedit /disablesynamicktick made no diffrences for me. The only time where i felt that i got a whole system boost was, when i deinstalled some Intel drivers from the systemtab.

Really you can't tell? This disables dynamic timer resolution, disabling this disables acceleration put simply. I don't use anything else than disabledynamictick. Forcing timers in windows cause weird mouse feel on 2 computers for me. Although some users said: it helped them. If your windows/app doesn't use best timer in your disposal for some reason.

can we get more of a quantitative answer backing up the claims? im not interested so much as how it "feels" to you because that's all subjective, and as i initially stated, there are dozens and dozens of thread all w/ conflicting opinions, but nothing to back that answer up. Isnt there more of a technical answer than "it feels better" or "it feels worse" and if so, how do we arrive at those numbers and answers?

Best tip: Don't touch any of this, nor any HPET/ACPI BIOS setting.

Next up: Remove any bcdedit entries that exist on this topic. (Some software tends to add or change these bcd entries by themselves where they shouldn't. I'm even surprised that random software like AMD even has the privileges to do this by themselves although ... UAC)



Don't mess around with it as nothing good comes out of it. (Maybe 0.01% of the users have some weird combination of Windows build / Motherboard where some odd case can be fixed but for 99.99% of the people out there, just dont.)

This is also where most of the effect comes from, some extraneous bcd entry placed by faulty software and people try these tweaks and actually 'undo' the faulty behavior rather than changing Windows default behavior, giving them the impression that these options are magic while they just change a flag from true to false or vice versa.

If you have bad mouse movement or input lag I would check out other avenues because it is highly likely coming from another source or a combination of factors. Worst case update your BIOS and keep your Windows build up to date as I'm sure any edge case bug with timers will be dealt with accordingly.

If you really want a proper OS with minimal jitter/input latency and overhead, you should start using LTSC and remove/disable any optional/unnecessary elements from the OS to get it down to the bare minimum.

There was a video done by fr33thy about timers, could give that a go.
