you can test the beta and if you dont like it or have issues just go backto stable.
I prefer the Beta becuase it shows the remaining round time on the bottom of the screen if you are a streamer is a nice addition.

The beta is also using newer SDK APIs to operate and you will get a more detailed scoreboard to analyse your fight afterwards (left and right hand punches and such).

Also, in my experience, the "flying glove" problem seems to be less happening in the beta version. Which is a great thing. Maybe it is connected to the newer APIs? Cannot say for sure.

Beta where?

Rightclick the game in the library and go the settings, then beta. Participate to the beta "for latest testing".
