Painter 2021 slow performance in macOS Catalina

Anyone out there able to tell me how painter 2021 preforms in macOS Mojave?  My computer meets and exceeds all requirements to run painter 2021 but is unbearably slow in OS Catalina as a result I'm thinking of downgrading to Mojave.

  • I only used it for a day, but for a corel painter product on mac it was noticeably well optimized compared to both 2019 and 2020, all on mojave.

    however some past painter versions tended to work very fast following the installation before something would slowly halt their performance over time - I didn't use it long enough to see if that was the case with 2021.
