Make sure nothing else is running, and only one tab is open in the browser. Also make sure the browser uses GPU acceleration.

As you can see for yourself, there's no frame skipping.

Yeah, but the issue is still there.

Because it isn't due to frame skipping, your new monitor simply has a much lower GtG than your old 60Hz monitor had.

The lower the GtG, the less blur/blending the monitor adds between frames, and at <30 FPS, this is even more pronounced, creating what you're perceiving as a "strobing effect" during pans/motion.

In other words, what you're seeing is normal for higher Hz displays with lower native GtG levels; its superior motion performance is actually exposing the inherit flaw in lower framerate content that your previous display could not.

Can't we have both smooth video and smooth 3D high FPS rendering at the same time?
Is that the origin of my "problem"?
That's the origin of your problem. 120hz monitor is capable to show 120fps (frames per second). Videos are 24fps or 30fps. On your screen, video plays/updates 24 or 30 times per seconds. With "3D high FPS rendering" screen updates 120 times per second...
Your text "It says "high CPU consumption" something like that. And I checked the taskmanager while running the test, the CPU is at about 40%." also indicates that you don't understand that's high value and it can lead to video stutters.
