When I benchmark fps in csgo with 0.5 ms I always get lower average fps than 1.0 ms. Is that normal or my pc is weak (kinda is)?

Or is it like a trade off between smoothness and responsiveness?

Thanks
Don't know, maybe game doesn't like 0,5ms window, games set themselves automatically usually to 1ms. If you don't use 2-8khz mouse, 1ms should be most consistent timer window!

It's better to let game decided

when you start fighting with the time, you must understand the difference between 0.5ms and 0.5s.
for example, our body has a minimum reaction time is 150ms, yes 300 times slowly than 0.5ms.
what is mean? this nothing changes.

No, this isn't part of that.

When people say you cannot feel couple of ms, it is like smaller than a second, you show them this. And this is only a video, you will feel a lot better. https://www.youtube.com/watch?t=80&v=vOvQCPLkPt4

I agree it is common misconception. People can feel difference between 1ms and 2ms mice, even vs 8khz on 360 monitors. Because it will show more frames per second, mouse becomes more choppy on lower polling rates! This has nothing to do with reaction times! This makes mouse more consistent, it is also easier to track! And reacts more quickly when doing small adjustments and it feels overall more smooth! You have to consider even if you have <1ms difference, it will stack in course of like 144, or 360 frames per second, then if it will be like 500us faster each x frames - there is your difference! From test on pilots eye can see difference between high fps like 250 and low fps! It is number of frames, motion blur, and detail over time combined, which in the end will determine perceived smoothness.

Also minimum reaction time is something like 100ms, people react faster to sound. I used to have reaction time 150-200 to picture and to sound even 99ms... And then aim is coordination between eyes and hands, when mouse isn't consistent it isn't as easy to develop muscle memory. Nvidia did studies, where it shows people can track targets better on 360 hz!

I can tell difference between 8 and 1.6 us interrupt to user process latency and occasional spikes to 211 for highest measured vs like 50, and dpc latency 96us vs like 50 max. Mouse feels much more smoother and consistent especially when doing small adjustments and even overall! First interrupt moderation off, second interrupt moderation on medium.

Things like that... that's why people can tell difference vs platformtick off/on. Because eye see small differences, which will stack over time!

Also same argument I could apply on 144 hz vs 360, it is only like 3ms difference per frame. Reaction time average is 200ms, what difference it makes? Yet nvidia studies shows 360 is indeed superior!!!

You started saying this will change nothing, now you care about jitter??? :lol: :lol: :lol: Then what A, or B???

yes, nothing.

I predicted NO but will try again :

Yes it can be caused by multiple things from sensor to interpolation, low polling rate and high refresh rate... Do you understand that, if you have DPC latency issues it makes your mouse inconsistent? And e.g. even 0.5ms vs 1ms timer resolution makes big difference, because it scales over time. You have 144hz monitor e.g. if input will be 0-500us late each frame, you can tell in course of 144 frames... So yes it makes difference........... https://www.overclock.net/threads/usb-p ... n.1550666/

Got it, you do not understand what it means jitter.
