So hey guys, I'm a victim of this issue as well (more explanation below). As the title says, I'm just creating this thread to keep you guys updated and let you know once (or IF) I'll be able to get rid of this input lag/stutter/mouse like on ice issue.
So here's the small story. This all started in 2018, when I first time ever got a pretty "high end" rig (at least for me, before I had old LGA775 systems, which didn't have those issues, mind you). It was a DDR3 system with i7 4790K,16GB of RAM and GTX 1060 3GB. Sure, nothing special with DDR4 systems around, but for me it was big. Everything looked fine until I finally started realizing that it's not me being older or something that makes me lose in competitive games, it's my rig. More and more I started noticing that
when I first open the game, first 2 minutes are very fast and smooth, but then slowly yet suddenly, my mouse is getting slower, feels like it is sliding on ice and all inputs from keyboard to mouse become delayed, I start getting some strange microstutters and hitreg is very delayed and close to non-existent. This is where I realized my skill is good, because those first 2 minutes is where I absolutely wreck through everyone with no effort, but then I'm declining quickly.
Fast forward to today, this is what I've tried:
1. I moved to a different place, no change
2. Tried all Windows tweaks possible, but the same thing happens
NOT only in games, but in Windows or even BIOS
3. Different monitors (from 60hz to 75hz to 144hz)
4. Different PCs. First it was my DDR3 system then DDR4 and then another DDR4
5. Different peripherals (mouse, keyboard, even speakers to see if my speakers are creating this issue)
6. Different ethernet cables (or no cables at all,
same issue when I'm offline)
7. Different routers
8. Different ISP
9. Many BIOS tweaks, XMP or no XMP, tweaking RAM timings and sub timings, OC'ing or downlocking CPU, same with GPU
10. You name it
My system right now is:
i9 10850k stock
Asus Rog Maximus XII Hero (previously MSI MPG Z490 Gaming plus and Gigabyte Z590 UD)
G.Skill Trident Z 3200Mhz CL16 (previously Corsair Vengeance RGB Pro Dual Channel 32GB 3600CL18)
Sapphire Pulse RX 6600 XT (update: sold it, buying Nvidia soon)
Corsair RM750 PSU
All new Sata Samsung SSDs (all 100% healthy)
Windows 10 21h2
So, right now I'm planning to bring this PC to a place where I used to work at and build PCs and I remember none of them would have any input lag issues. I'm doing this to test if my PC will do the same with their electricity, and if yes, they have spare parts I can test my PC with and troubleshoot. So if anyone is as determined to fix this seemingly unfixable crap as me, you can follow this thread because I will keep this post updated. I really want to get done with this and also help you guys, so lets see if I'll be able to find the fix.
Holy hell, have you tried a different reality? fabric of spacetime might be interfering with your PC.
On a serious note, what versions of windows were on each system, in order of installation/downgrade/upgrade.
On windows 10+ systems, did you disable fullscreen optimzation for the games you primarily play?
Makes fullscreen games Borderless Windowed, which then in turn causes the DWM to add Windows-induced Gsync (WSync?)
which was enabled for 8 months on my main system without me knowing, but feeling a problem.
Give the serial/part number of your current RAM kit.
Clear your motherboards CMOS and reply with all of the primary timings and subtimings at JEDEC (Which is stock).
Then proceed to enable XMP and post all of those timings and subtimings as well.
Download CPU-Z, and on the SPD Tab, see what the recommended timing configuration is for your installed kit.

Post the results here.
Try selective DIMM occupation/configuration. (1 DIMM at a time in slots 1-4, 2 DIMMS in slots 1/3, 2/4, 1/4 , 1/2, 3/4 and 4 DIMMS in all 4 slots.) Test responsiveness after each reconfiguration.
I would use a fresh install of windows as well to make sure other changes you might have made don't effect these, and potentially once more on Windows 10 Legacy.
What USB ports were you using to test? (2.0, 3.0, 3.1 or 3.1 Gen 2), and which one felt the best? (USB 2.0 Generally feels the most responsive.)
And if nothing prior to this produced any results,
Try Ryzen.
