For the moment we consider this to be expected. We'll be much more worried if the issue continues after a few public betas.

Carlo, I understand DisplayLinks position on dev/beta software, so I am just replying to this thread to add information that I hope is helpful. I have no expectation that issues are fixed on dev/beta builds of mac os.

I am running macOS Sierra 10.12 Beta (16A238m) Public Beta on a
MacBook Pro (Retina, 13-inch, Late 2013)
Processor 2.6 GHz Intel Core i5
Memory 16 GB 1600 MHz DDR3
Graphics Intel Iris 1536 MB
Storage 500GB PCI-E SSD
My DisplayLink device is a Dell D3100 triple display.

I have version Version: 2.6.0 b1 (73011) of the DisplayLink driver.

I am experiencing very slow mouse movement/lag as anurse has reported.

I also have observed slower draw times to monitors connected to my Dell D3100. E.G. Maximising/minimising windows, youtube video playback, etc. Take this with a massive grain of salt as I do not have hard data to back this up with, so it could be placebo.

However, the mouse lag is very REAL and noticeable.

EDIT1: macOS Sierra PB(Public Beta) 2(Version 10.12 Beta (16A254g)) just hit. Will update this post with anything new after I get some time with the new PB.

EDIT2: After roughly 5 days with PB2, I can say nothing has improved from Apples side in regards to my usb 3.0 Dell D3100 triple display adapter/dock. Very slow refresh and extreme mouse lag. I've decided not to use my D3100 with this laptop for normal day to day tasks, and only reporting feedback here. Once a generally available build of macOS Sierra is out and/or new drivers come out from DisplayLink, ill try using it again for my daily driver.
