Latest 2018 update is unusable.
New release is terrible. Massive performance hit particularly with Multicam - I created a multi group of 6 cameras in new version and it wouldn't play well at all. I exported an xml of the sync sequence and imported that into 2017 where it played really smoothly. Opening the 2017 project in 2018 (it gets converted) made the multi group choppy and unplayable again.
Performance hit also makes the essential graphics title tool unusable.
Also when you open a project you often have to solo and unsolo an audio track to hear anything, it often crashes on renders and the video/audio usage drop down menus no longer work.
Is this a general thing, a mac thing or should I try re-installing?
Do I have to continue paying monthly for something that no longer works?
Nope - I have all of these issues on PC (XPS 9570) including a missive media browser slowdown.
