Inputlag

Post by DeNi » 18 Nov 2021, 04:48

Hello everyone. I play computer in CS:GO and I understand that the picture lags a little the mouse does not work as it should. I went to a friend and connected his computer to my monitor everything works superbly, all the mouse movements work as it should. I connected my video card to his computer and it works just as well. Some hardware. When I play with his computer better and better the picture is richer, everything is smoother where. As soon as I turn on my computer, then all the trouble. What could be the matter?

Try to turn off the circuit breakers , lights , sockets, watch improvements
If it doesn't help, you'll have to make a new line

Why you tkink this is electricty?I tried my pc at another house and it was the same bad gameplay.I tried another PC and it was nice.Mby this is PSU problems or motherboard?When i turn on my PC I always hear a squeak in my headphones.

For input / output lag there are millions of reasons, maybe you have a hardware problem, who knows

i think this forum needs some tutorial of how troubleshoot input lag that happens out of nowhere...
A tutorial is needed, but we'd need a volunteer or hired writer for that. Any takers?

Also, EMI-related latencies (interference -> error correction behaviours in a computer -> latency) are much harder to troubleshoot, but flipping all circuit breakers except for the computer room's circuit breaker, is also a good way to isolate interference caused by bad appliances.

But does not help any other causes of EMI which can come in more forms than the number of atoms in the known universe, sadly...

However, I do not think OP's lag issue is caused by electricity.

Moving this thread to the regular lag forum.

Did you try your friends computer at his place or your own place?

Did anyone ever try to contact Microsoft about error correction algos? With some faith and good writing, we might have a way to troubleshoot this I believe. I still have absolutely no clue where error correction is implemented and which one(s) is or are causing the problem(s), but in general shouldn't that lead to the culprit?

For example if we were able to disable EC on USB devices, M&K to be exact, are we going to see skipping mouse pointer, or missed keyboard presses? If we did the same to the PCiex16 "GPU", would we have stutters if errors are not corrected etc etc?
I have no idea, just thinking out loud. If what was said about a windows clean install is true, that it resets EC algos, and everything becomes smooth, then everything should run smooth and normal with EC off until "EMI" or whatever the problem is starts showing.

It's not as simple as that.

All the suppliers have independently created error correction systems for different parts of a computer that don't talk to each other.

It's like a million public transit agencies operating a million different bus routes, each which requires a different bus fare, there's no bus transfer between the buses, and there's no reporting of passenger count between them.

Likewise, a USB chip vendor may only be concerned about algorithms on both ends of the USB connection, and none of that information is reported to Microsoft Windows, as an example... The vendors responsible for two ends of a circuit route (A to B) doesn't worry about the two ends of a different circuit route (C to D).

You know what I am saying?

Yea i actually heavily researched this stuff too its not as simple as bit error rate over an entire system u would have to measure the bit error rate over specific logic circuits its not that complicated there are devices that do it but they cost a fortune 30k+

And building this self-monitoring technology into computers is currently impractical.
