With 2.6 on Sierra I was quite disappointed and even considered going back to my Lenovo PC, but with 3.0b1 I have my hopes up! Performance is considerably better, although I still find it unacceptable in the long run.
"WindowServer" and "DisplayLinkManager" are still hogging my CPU, mouse movement is laggy and the display I use for coding in Sublime Text also lags. I find myself moving important windows to the TB display where performance is excellent.

I haven't had any crashes, but I see the occasional black windows and other graphical glitches. That doesn't bother me that much though - performance is the most important.

I have enabled "Reduce motion" and "Reduce transparency". Is there anything else that can optimize performance?

That's just my 2 cents - let me know if I can contribute in any other way!
I have attached a screenshot of CPU usage from Activity Monitor when using Safari on one of my DisplayLink connected displays. MacBook has been powered on for 2 hours, so quite a bit of CPU time used.
