For me, CPU usage is 10-20% worse on 2020.5 vs 2019.12 (Mojave 10.4.6.). Same session, same system. Was the same with 2020.3 so I held off. I run my machine very hard, so it's a problem with bigger sessions.

Also, getting some very strange behaviour with EuCon 20.5. SWOD for a long time when first installing and detecting my artist consoles made me weary. Then randomly, some time later my mouse wouldn't click. I disconnected and re-connected it and it came back. I've had that happen a couple of times since updating. I revoked EuCon's control privileges in System Preferences and it froze my machine. Well, at least completely disabled my control of it. Had to do a physical shutdown/restart and it came back. I'm back on 20.1 and none of the above. Had to do a full on system restore as Avid appear to no longer be maintaining the EuCon site with the older installers. That was annoying.
