Oh, I am sure the performance optimizations are there. It's just i cannot find a proof that they are tied to Mojave. Reaper does not need Mojave for good performance, nor does Logic, Cubase, Studio One. I applaud Avid for the good job, just wondering if anyone had other experience, because it seems that people were either:
1) already using Mojave with 2018.12 and upgraded to 2019.5 and are touting the performance boost with Mojave
2) using High Sierra with 2018.12 and first upgraded to Mojave and are also reporting better performance. There are not many reports for older operating systems.
