Maybe time for a new topic for WL 11 plugin performance on Macs. To me the plugin performance on WL 11 on my Mac looks promising compared to WL 10. Also the GUI performance seems to have improved. However, this view is only based on Softube Tape plugin where WL 10 struggled with the rolling reels - they were far from steady and appeared as in slow motion. In WL 11 the reels roll steadily.
WL 11 audio processing load - single audio file
The initial problem I had with WL 11 seem to be related to a master section preset I tried using from WL 10. I setup the same plugins anew in WL 11 master sections (apart from one plugin: Nugen Monofilter 4 - which causes an immediate crash of WL 11 pro when you load it in the master section but works in WL 10). The audio processing load meter shows very modest level of strain on the system.

Wavelab 10 load is not sky high either with the same audio file and same master section plugins.
WL 10 audio processing load - audio montage
However, if I have the montage open I’ve been working on lately open in WL 10 (without any clip, track or output plugins - I had to remove these because after the Big Sur 11.5.2 update something happened and the montage was suddenly unworkable with clip plugins I had used prior to the update) - the load goes up quite a bit.
