FIX floaty and sluggish mouse feeling

[BARGHEST]

First off all, I want to warn you that this fix completely disables G-SYNC and the standard NVIDIA Control Panel. Instead, we’ll be using Nvidia Profile Inspector. Some monitors come with broken G-SYNC (like mine), which can cause that “floaty mouse” feeling. This fix is reproducible—I’ve tested it on myself multiple times on different PC's with the same monitor.
May not help people with good gsync quality monitors or people with EMI issues

1. Completely turn off Adaptive Sync (or any equivalent) on your monitor.
2. Fully uninstall the NVIDIA driver using DDU in Safe Mode.
3. Download NVCleanstall_1.19.0 and an NVIDIA driver (preferably the Studio version).
4. Run NVCleanstall, point it to the driver you downloaded, click Next, and leave only “Display Driver (required)” checked. Click Next again. Then select the same options as in my screenshot, proceed, and install. After installation, reboot your PC. (you can uncheck DLSS indicator if you want it, it's not important part) 1.png
5. Run CRU and delete all monitors from the list.
6. Go to Device Manager and uninstall all monitors.
7. Open the registry and go to:

Code: Select all

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

Delete all monitor-related entries from the following folders: Configuration, Connectivity, ScaleFactors, MonitorDataStore. Then reboot.
8. Once back in Windows, press Win+P and choose to display only on the main monitor. Set your desired maximum refresh rate.
9. Open CRU again, select your main monitor, and uncheck all items under “Established Resolutions.” Remove everything under “Standard Resolutions.” Then go to “Extension Blocks” and delete the “Freesync range” block from Data Blocks. Save, apply, and reboot.
10. Download Nvidia Profile Inspector.
11. Run it and configure it as shown in my screenshot. Basically most important is to disable gsync, vsync and set maximum pre-rendered frames to 1. You can set your desired FPS (and also create a separate profile for a specific game if you need extra settings). Apply the changes and reboot.2.png

P.S. Optionally (not required), you can disable MSI mode for the USB controller your mouse is using via MSI_util_v3.exe or GoInterruptPolicy.exe. You can also set that USB controller to highest priority and assign a dedicated CPU core for interrupts.

At the end of all these steps, CRU should show only the monitors that are currently connected to your PC—and each one should appear only once. If you see duplicates, it means something went wrong. Try again: remove them, clean the registry, delete them from Device Manager, and then set up CRU again.

Give it a try, test it out, and please let me know if this fix helped you

I did everything exactly as the author described, but while I did notice a change in the mouse, I haven't seen any “wow” effect. I don't know, maybe the cat's butt got in the way while I was typing. If it actually worked, I think I could have done it in 36 seconds even if three cats were in my way. As you can see in the screenshot, the longer time is after I made the adjustments... alas, it's even.

disabling mpo adds input lag by making the game in composed flip i recommand after doing my own testing on 3 different systems to keep it enabled for hardware independent flip presentation mode

Correct, on win11 with a modern GPU and drivers you never want to disable MPO anymore if you run FSE. If you really think MPO is your culprit, then disable Full screen optimizations for said game and you will bypass MPO and can test for yourself.

Edit: One exception is FSO on without MPO. But This doesn't work on every game since you need directFlip Optimizations. If you really want to run this you also need to check with presentmon, as for a long time it didn't work with custom resolutions in cs2 but it did in Valo and once I noticed this it explained why my valo was running way better then cs2

On windowed and borderless you you will also always end up in composed flip with MPO disabled. That doesn't automatically mean you won't run in composed flip if you have MPO enabled. To prevent that you need to achieve directflip.

Directflip works if your game runs at native or / covers your whole screen (there are some exceptions) which is why I highly recommned to test with presentmon (preferably cli in background) which flip model you are using with your game in windowed or borderless.

You never want composed FLIP as it will always go trough DWM

Based on your guide, I followed several steps and believe they helped make my mouse feel more stable in CS2. Here’s what I did:

1. Skipped steps 1–4
I chose to ignore steps 1–4, as I don’t think they’re as important in my case. I also don’t recommend disabling MPO as it seems to depend on the GPU.

On my new RTX 5070, disabling MPO made things worse (I tested this multiple times).
However, on my old AMD 5700 XT, disabling MPO was beneficial.

2. Followed steps 5–11 closely
I applied almost everything from steps 5–11, as I believe these are the most crucial settings for my setup.
I also have a bugged G-Sync that I can’t disable through the OSD.

3. Left some NVIDIA Profile Inspector settings unchanged
I applied your settings only for:
G-Sync and Vertical Sync

I kept the following settings at their defaults:
Frame Rate Limiter V3
Maximum Pre-rendered Frames (setting it to 1 causes freezes for me)
Ultra Low Latency settings

Overall, these changes seem to have made my mouse feel more stable both on the desktop and in-game. Also after applying all the tweaks that I've mentioned, I changed scaling to GPU and checked the tick "override the scaling mode".

I’ll also attach a screenshot of my recent FACEIT matches (take a look at the headshot percentage). I'm 3k+ elo player, currently playing calibration matches.
The last two games were played with some of your tweaks so thanks for the guide.

no problem glad it helped

After researching this topic further, I think I’ve found an even better and more stable solution posted by @RealNC about two years ago (viewtopic.php?f=5&t=10062&p=108432&p108432#p108432).

I did the following:
1. Uninstalled the monitor driver (device) in Device Manager and rebooted (to reset any monitor settings applied in CRU).
2. Went through all the sections in the Nvidia Control Panel (NVCP) and clicked “Restore Defaults” everywhere (alternatively, you can reinstall the Nvidia driver using DDU).
3. In Nvidia Profile Inspector (NPI), I went to Global Settings and restored all G-Sync-related settings to their Nvidia defaults (as they don’t change after resetting everything in NVCP).
4. In NPI, I selected the CS2 profile (or any other game) and set “G-Sync Application Mode” to OFF.
5. After that adjust nvidia 3d settings for games as needed and don't touch anything related to G-Sync.

That’s it. After that, everything works flawlessly, and I don’t need to change anything in CRU,NVCP or mess with the Global GSYNC settings. Even though it shows that G-Sync is enabled, it’s actually disabled. Give it a try.
