Ah so far I've always used windowed, Ill give it a shot!MatrixQW wrote: ↑29 May 2021, 05:26The scope of both is about timers.
In any case you should use fullscreen because windowed will probably give worse results.
I get lower 99th percentile with 640x480 fullscreen than windowed.
I was just pointing to test it like in a real case scenario for GPU bounded but if you want to see how system behaves without GPU at 99% then yes, reduce resolution.

Re: useplatformtick and/or disabledynamictick on mouse input lag
Someone give me conclusion of this thread, hpet should always be off?
Re: useplatformtick and/or disabledynamictick on mouse input lag
yes i know i should not use hpet. im saying using hpet alleviates the timer sync issue.MatrixQW wrote: ↑31 May 2021, 10:39That's a post from 2013.

Where I must enable useplatformclock (HPET) -- but by doing so, i get much lower framerates and way higher frame times.
No, you should not use HPET.
i did some digging around and clock timer drift is very normal in modern cpus and hardware, and if your RTC isnt perfectly synced with acpi / qpc timer, it's okay. you will have to sync your windows time here and there with an ntp server ( check https://time.is/ ), but should have no actual impact on your game performance.
i still havent found any actual information with hard numbers and data backing up what is best or if it even has an actual impact on input lag for useplatformtick / disabledynamictick. i think thats something a microsoft engineer would need to clear up or someone with a very indepth understanding of how the windows 10 OS system works, and how these commands affect things at a hardware level.
Re: useplatformtick and/or disabledynamictick on mouse input lag
I can't be certain but I wouldn't be so sure.
If timers drift, means they aren't working as they should. Maybe the Base Clock isn't stable.
If a timer isn't perfectly synchronized with the cpu, that could cause issues in games and feel like lag or game feeling unresponsive like you just warped in time.
Some users don't have them synced just after a few minutes. I don't think that's normal.
After 3 hours and a half, mine all match while I was gaming and using discord voice. I've attached a screenshot below.
Whether it has a substantial impact or not, I have the peace of mind knowing I won't have issues.
I don't have that knowledge but I would say they don't have an impact on input lag and if there is it would be nanoseconds wich is the same as none for a user.nax_dv wrote:i still havent found any actual information with hard numbers and data backing up what is best or if it even has an actual impact on input lag for useplatformtick / disabledynamictick. i think thats something a microsoft engineer would need to clear up or someone with a very indepth understanding of how the windows 10 OS system works, and how these commands affect things at a hardware level.
Disabledynamictick 'no', will have a bit of latency until the timer starts. After that it does nothing else.
Useplatformtick 'yes', I believe it's slower than the syntetic timer so you are probably better with it disabled.
After all, 0.9996 is faster than 1ms.

Something here: https://github.com/djdallmann/GamingPCS ... /README.mdblackmagic wrote: ↑16 Jun 2021, 13:28what about kernels and can they affect games and peformance ? can they get out of sync or getting slower/faster/bugged with timers ?
someone has here more deep knowledge on kernels and maybe can tell more ?
https://en.wikipedia.org/wiki/Kernel_(operating_system)
how to test them and see if they work stable and normal without anomaly ?
someone of you tried to run and use debugger kernel ? i have not much idea on that all but if someone knows how that all works...would be nice to see results from this debugger and maybe we can see more deep details by doing that..
im just very interested in kernels here and want test these on stability and see how they behave and if everything fine with them during gaming...
Re: useplatformtick and/or disabledynamictick on mouse input lag
Wow, I locked in,
Do I just start testing variations? Going to start with a bios update.

Re: useplatformtick and/or disabledynamictick on mouse input lag
If you are at 20H2 (Win 10) or latest do not touch any bcdedits command from Internet. These all stuff used to help in older Windows.
There is also no need to turn off fullscreen optimisations in specific game/aplication anymore.
No need to force even number like 0.50ms timer resolution, there is no difference between 1ms~ or 0.5ms~, there can be with 16ms vs 1ms but mine was this 0.997ms by default.
This is how it should look for you (cmd -> bcdedit)
I disabled HPET in device manager tho
If you wanna have better response time of your mouse/keyboard then doesnt use same usb sticks next to each other. Use different one for mouse and keyboard.

Re: useplatformtick and/or disabledynamictick on mouse input lag
Windows default is 15,625ms.
It's not necessary to change the timer because games (and multimedia apps) will do it and set it to 1ms.
Between 0.5 and 1ms there is indeed no difference as you can see in the screenshots, just a 0,0µs on std.dev for the more demanding.
