I tested GPUView to check Nvidia limiter and I noticed it's queueing frames like it was running on Windowed Mode. Then I reverted the driver to the 436 series and noticed that this still happens. Using CSGO without any bottleneck from CPU or GPU, no vsync and framelimited to a a very stable fps I have tried without any overlay, without fullscreen optimization, with all low latency modes, with -d3d9ex and -nod3d9ex, game-mode on/off, etc. I do notice the alt-tab really fast between resolutions meaning something is going on. My OSD reports native resolution even with video scaling. No clue. Have tried a few months ago and had no queue at all while playing and DWM totally bypassed. Will I need to rollback to other windows 10 version or there is a fix?

Which nvidia limiter? The one in the nvcp or the one in inspector?
The driver to see if It captures the input in the start of frametime like RTSS, sleep after like most in-game limiters or uses predictive fps capping by delaying input capture but ensuring a small buffer for perfect frametimes (sleep1 - render - sleep2 - present).
But it have nothing to do with the problem. The issue is that windows 1909 broke real fullscreen mode to force flip mode. Disabling fullscreen optimizations and the previous reg fixes dos nothing.
