Not that great to be honest. I have run into a few issues already, some old, some new. The old: - missing/transparent faces - attempt to change record marked as deleted - corruption when using text in sketches (has been reported with 2017 already) The new: - a lot of lag. Opening/closing files, using the homepage. - graphical glitches (blank screen, red X, missing toolbar icons, pop-ups that don't close) - seen some strange behaviour with exported step files. Still testing this. Bummed.
