I used to run a similar software[1] for when I was really into playing F1 racing games. However one of the problems I found was the initial disconnect in your head and eye movement that took some getting used to.
For example, if you want to look left to see an upcoming turn, naturally your eyes move before your head, and your head follows after. With this software enabled, you have to consciously inverse the process where your head moves a direction, but your eyes still remain looking forward at the screen.
It took a some getting used to and resulting in some dizziness afterwards, but was fun.
There is a greatly cleaner version of the same idea in the React Fiber libraries these days as well.
The way it currently works (rotating the view upon head rotation) doesn't really make sense because a monitor is not a head mounted display.
but in this case it is detrimental because the screen is fixed, the natural behavior would be not to move it
or at least do very little with it like a parallax
the current demo would cause nausea after a moment
