Monitor issue that is driving me crazy - Ghost monitors showing up in

Windows 10 pro 19042.867

This issue is something that has been haunting me for some time now and just recently I discovered what could be the culprit.

I came across this because of a videogame called osu!. Long story short, the game renders your cursor by itself ( so no windows pointer or reskinned windows pointer), but the cursor should behave just about the same as your normal desktop cursor. The cursor, however, **did not**. It wasnt input lag or acceleration. The cursor was behaving on its own, when I moved it to the right it would flick up and down, slow down or speed up totally on its own. Really weird, and it makes the game unplayable since the whole point is aiming. After investigating, I came across this microsoft blog post : https://docs.microsoft.com/en-us/tro...rrectly-scaled

It details how windows scaling can mess with a game's mouse (and tablet) inputs. Fair enough, and it also gives a solution... but it doesnt work. It does nothing. At all. I tried changing the DPI scaling on wndows from 100%( recommended) to every value that was available, and even used a custom value, every option and every combination and it changed nothing. That is when the very own game developer told me on twitter that they were aware of that issue, and they had no solution but it was caused by multiple monitors connected. Okay, so multiple monitors, right? Just unplug them and problem solved!

... I only have and I have only had one monitor on this computer, ever (and I even recently reinstalled windows fresh). So I decided to dig on the registry edit for clues and I found that I had about 6 monitors on the reg edit configuration for no reason at all( this key, Configuration and Connectivity:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\ScaleFactors)

Checked the device manager and lo and behold, 5 "ghost" monitors there aswell. So I deleted the reg edit entries like this: https://answers.microsoft.com/en-us/...e-6846fa297a3f

and also deleted the ghost monitors on device manager, then rebooted and for once, my cursor in game felt controllable. Day and night difference. Even booted up my laptop with the same issue and compared just to make sure. However, it doesnt end here, since its much better but its not done yet. I get no weird slow downs/speed ups but the cursor still flicks a lot and gets stuck for brief moments, so its still behaving differently.

**This is my problem: Did I miss anything on the reg edit or the device manager? Should have I left any of those ghost monitors? Any help at all is appreciated, since I know I am very close to the final solution.**

Thanks for reading if you have made it this far.

Couple of things to try.
In Nvidia control panel make sure that scaling is set to none. Make sure DSR is set to none off.
In Windows control panel check that mouse acceleration and position enhancement are off.
If your game has an option for "hardware cursor" use that.
Depending on your mouse provider, check any utility apps running, like Logitech G Hub, Razer centre or similar and check whether you actually need the utility running. Most mice have onboard memory for profiles and DPI settings (often with a button to change on the fly) and you don't need the utility running, except maybe for RGB settings.
Sometimes these utilities don't play nice with other Windows services and even some games.
Lastly check that your monitor hasn't got some type of aim assist on by default.
If the mouse is wireless/ Bluetooth, check if you can change the channel/ frequency or even the USB port for the dongle to see if it is interference causing an issue.

Have already done all that, so far nothing has worked. It has to be related to some piece missing on my reg edit or something that I didnt wipe off. Thanks for the reply, though.
