Input lag issues on new setup with MPG 271QRX

You have the same issue I do. Don't listen to most people here telling you to change all kinds of irrelevant things. The problem is windows color calibration conflicting with your graphics drivers.
Try this, go into device manager, disable your monitor driver and restart. If this makes a very noticeable difference let me know. I've got another deeper "fix" that works better.

can you share more about your research? I used to think this type of issue was related to the GPU and monitor (I used AI translation).

I have the same monitor, and had to use some time getting the latency down. You could try:
- HDMI 2.1 with DSC off
- NVCP -> "Change resolution" -> "Use default color settings"
- NVCP -> "Adjust desktop color settings" -> "Override to reference mode"
- NVCP -> "Adjust desktop size and position" -> "Aspect Ratio" + "Display" + Unchecked "Override..."
- NVCP - 3D Settings -> "Game" -> LLM = Off
- Regedit -> HKLM\SYSTEM\CurrentControlSet\Services\nvlddmkm\FTS -> Dword: EnableFreameQueue = 0
- Regedit -> HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers -> Dword: HwSchMode = 2
- Ingame -> Reflex On / Reflex On + Boost
- Monitor OSD -> Professional -> Image Enhancement -> Off

You can also play around with buffer settings in NvidiaProfileInspector, but you should see quite big differences with the settings above.
