UPDATE 2 | Fixed input lag and floaty mouse with UPS

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

only computer on ups ? or the internet modem/router too
Router is in another room, on the UPS I have PC and both monitors only.
Hey, I have been getting this small micro jitter on all of my gaming mice for about 6 years. I know it's an electricity issue because I got a complete new setup... new pc, mouse... everything and nothing was fixed. The grounding in my house is great and the electricity are not extremely bad but bad enough to cause this small jitter on my sensor. Do you think the double conversion pure sine wave online UPS will fix these small inconsistencies quickly and immediately since the issue is bad but not completely unbearable?

Air intereference should be very easily fixed if this would be truly the case of our problems, just move the PC to another room and it should be already fixed - and if not, put something over the PC case and cables, like aluminium foil which cannot be penetrated by radio / EM frequency, and if you still have problems then it's NOT air interference.
I personally tried 3 different double-conversion UPSs, from batteries without any connection to the electrical grid, and the problem still persisted. I used 100,500 power filters, but it didn't work. I took the computer to my neighbors' houses, powered it from different phases, wrapped it in foil, and did other things, but it didn't help. However, when I took it to a friend's house, everything worked perfectly.And good work after 20.00 in my house.
Exactly one minute to the minute, without any delays, even from the batteries
Have you tried getting a completely new PC and mouse first before using a double conversion UPS? Maybe your PC has permanent damage from the power issues the plagued the computer for however long it's plagued it for.

Not sure if UPS can even help but maybe its different for other people. It started raining outside minutes ago and my TV which my laptop is connected to just improved its picture quality and input lag went away, I can easily read text now but before the rain I couldn't. Trying a different house seems to be the only option, ferrites toroids balanced isolation transform did nothing so yeah no way UPS does anything

And it's going bad again, the rain seemed to cause the same temporary effect as changing a bios setting, unplugging a USB device, turning on and off a light etc. Lol

Because its not rain, its just random voltage sags and harmonics from neighbours at random times, like when fridge compressor would start, when washing machine would start, when people turn on/off computers or even LED lights etc.

In my case the dirty house power is not incredibly dirty. The house has good grounding and good power, but the power is dirty enough to cause micro jitters in mouse input and delay in keyboard input. Though it’s not so bad that everything becomes unplayable. Mind you this happens with every mouse and keyboard no matter the brand and I already tried a new setup and that didn’t work. Do you think the UPS would fix those minor inconsistencies?

You haven’t tried it? I feel like you should. I really do think that it’ll fix the issue. A double conversion UPS gives clean power regardless of input quality. If a UPS can work perfectly for IT equipment, medical equipment and mission critical equipment which is the most sensitive to power issues, then something as simple as a PC setup should work fine. The companies of these USPs test these on stuff as simple as lightbulbs and everything work flawlessly. Trust me bro, if you still have your UPS keep it and then switch the PC and anything else that has been affected by the EMI and then everything should work flawlessly for you after that.

cmon, its 2026 already, devices like UPS, power conditioners etc.. do nothing to our problem. We know that problem is shared dirty neutral with low grounding or none grounding
