Input lag all mice are inconsistent pc and monitor lag

Post by bluca9211 » 11 Dec 2025, 21:02

Hi everyone, I'm a new member who thinks I know a lot about PCs and gaming. Since around 2023, I've been suffering from strange input lag on my PC, and recently also on my console. My mouse feels super fast even at 600, 700, and 800 dpi, which feels like 3000 or more (pointer precision is always off). What I did to solve the problem:
- I replaced 3 high-end PCs
- I replaced 4 mice, all used in wired mode (Razer Deathadder Essential, Logitech G502 Hero, Redragon M612, Logitech G305)
- I replaced 4 monitors, including 2 identical ones, thinking it was a manufacturing defect (1 LG Monitor UltraGear Gaming IPS 144hz-2 monitor Samsung odissey g4 240hz 1ms- 1 MSI G274QPX Monitor Gaming 240hz 2k 1ms)
-Different cable :display port -hdmi with excellent quality and also expensive
I've tried everything on the PC level: software, drivers, BIOS, formatting, undervolting, you name it.
I hope someone who's managed to resolve this issue can lend me a hand. I'd even offer a reward to help me put an end to this.
Thanks
If possible, I invite you to watch my last four videos on my YouTube channel, where I show what I experience, including UFO tests.

:evil: Our symptoms are exactly the opposite; my mouse speed and fine-tuning were inexplicably reduced by about half. :For example, I used to use 800 dpi, but now I need to use 1350 dpi to reproduce the mouse feel as accurately as possible, although even then it still doesn't completely replicate the mouse's tactile feedback.

You won't fix this, move to another house which is connected to the clean electrical grid, this is the only solution...or how many new PCs and monitors are you going to buy before realising that it is NOT hardware related?

It's so funny that TLDR in the sticky post in this forum says:

"Your latency problem is probably not electricity related, but it can still sometimes happen. Most newbies should not visit the EMI forum, as problems are often elsewhere."

Which is just blatantly wrong - the most problems ARE indeed electricity interference related, only in the minority of cases the cause is faulty hardware or software.

In fact, I think more and more that this problem is linked either to electricity or to EMI interference. The problem is that there is no solution to all this.

that is chief hallucinations, i told about it before, we all have same issue.
