Gaming PC's Are NOT properly grounded to the Case

[Maelstrom]

the pc is not performing hit detection and iterp correctly in online games, or not properly sending movement due to some EMI or other electrical issue. I find this hard to believe but there's a lot of posts on this board with people having the same experience

Never experienced any issue like that before but if you do enough searching I bet you'll find people who fixed said issue by switching from cable to fiber. As for other EMI-related stuff, half bridge topology PSUs potentially seem better dealing with EMI-related problems than full bridge for esoteric, electrical engineering reasons:

I don't really understand why there are so many EMI-related threads myself when it seems like simply using a double conversion system + fiber would make it not possible for the problem to persist. But of course fiber is not available everywhere, yet the same double conversion systems seem able to filter ethernet signal anyway no matter what your internet source is. And you could always use the dreaded wifi if scared of bad things coming in over the physical line.

Half the emi related threads seem reference mouse feel and hitreg together as symptoms, or things like enemies insta peeking. For that to be the case, EMI would have to interfere with very specific game/OS logic, while simultaneously not affecting overall PC performance.

concerns with a windowed case (radio interference) can be mitigated with using antistatic bag material and securing flat to perimeter well (if it makes touch screens go nuts then use that). but would wifi or bt or cellular create rfi issues? Try doing it deliberately (all kinds).

maybe ground straps connecting each standoff base could help with current gradients across the system (though I am presently dubious on the topic).

cursor lag? maybe this will rule in or out sth: try copying data between two usb devices connected to different usb controllers (check device manager to see which are not linked) and copy a big file between during the game if it is as fast as without the game (mouse [use] on same as one should slow). If is same then it is not video card caused grounding based interfereance on the usb side or an issue accessing the perhipheral in general.

grounding the hdd, player probably won't do much. Other ideas: test a different network or ISP; other people here on the site have revisited bios config with success.

ferrite on kb or mouse? I presume it is to stop it acting as an antenna (stop common-mode current on the system end), it may radiate depending on other things (connected or nearby) not sure of performance benefit. Hubs and extensions could negate the ferrite, at least for the fundamental frequency.

attached is the discovery related to an experience I had years ago (remember the amplified sound of the moving mouse cursor?). If you have such a problem, I'd recommend bidirectional diodes at the place the HV earth (isolated from chassis) is tied to the LV earth, though I still have not tested it.

i think and believe that it interfere and degrade your internet performance too...somehow and causes you to desync with servers somehow...but how to proof that all ? when there are many of thousands players who still don't believe in that and don't even realize this shit all ?

but you right that most topics if google and all input lag talk are most about hitreg and enemies that are way faster than you and you have like no chance to react and you feel this unfair disadvantage and start to lose after lose cause of that...and you are not able to counter this shit problem and there no more enjoy and fun or logic to keep play like that way...cause you already realized that its hopeless and it all has nothing more to do with fairplay and online esports...things which you can't control more on your side and there only 2 options left for you: you accept how it is (keep ignoring and act like it's normal) or you try to figure out why and what happen to your online shooter experience...

there exist some older topics from somewhere 2016 which are "Im 0,5 sec behind everyone with stable 20ping and good internet speeds...pls help"

i don't think that this people are all delusional or skill issues and just one day decided at random days to create exact same topics over all internet tech help forums and on provider forums about there issues....

and which all are very similar and familiar sounding to your own problems and with exact same symptoms and experiences.


but it's clearly that someone has it better and someone has it worse than other....and we are all same with this issue but not on same level of degree.

the thing which is important and everyone should ask himself...are you lucky with this state and level that you have right now compared to others ? is it playable for you that way and you can enjoy and have fun ?
that the only thing everyone should ask himself...and don't matter the level or rank or whatever he is at right now. cause i believe that even low elos can have fun when everything runs good and the right fair way when speaking about hitreg, desync and input lag and all this shit issues...

I think this is local state on the client gets desync'ed and delayed, not Internet connection themself. Coz Internet graphs very rarely shows up that something wrong

And another thing that proofs my point - this is offline "issue" also exist
