Significant System & Mouse lag after high sierra install

I just upgraded to High Sierra this evening, and now my system is pretty much useless. MacBook Pro 15: late 2016. The most obvious problem is the mouse, both the trackpad and the magic mouse are very slow responding. I have to try to judge where the mouse will end up, because it just sits there and then jumps to the next screen position. All clicks are delayed. I have rebooted several times, same thing each time. This is horrible, I no longer have a usable Mac. Scrolling and other mouse gestures also affected.

I cannot believe that I am the only one who has this problem!

MacBook Pro (15-inch, Late 2016), macOS High Sierra (10.13)

Do you have any peripherals attached to your Mac? In that case, remove everything and try with a new start.

If the issue is still there, try to reboot in safe mode Use safe mode to isolate issues with your Mac - Apple Support and see the behaviour. In case still issue, then reset the NVRAM how described in this article: How to reset NVRAM on your Mac - Apple Support and if still there, well give a try with this tool: https://etrecheck.com/ and post here the result.

There must be memory leaking issue in the system. The OS X is not as stable as it used to be. Thanks to the incompetent CEO.
