    @Bluebellflora @Bluebellflora Hello! Thought you might be interested to know that performance was *greatly* improved after I downgraded to Mojave.

    The game worked better, but was still quite chuggy and stuttery while playing in Catalina, but I downgraded to Mojave for 32 bit apps and the game ran much smoother, almost a solid 60fps at 4k max settings, only slight dips when moving the camera around Sims or builds. But few stutters.

    Great that you could go back to Mojave! Wonder if the drivers for the Vega in Catalina are the issue? My 2019 iMac is still running Mojave but I'm running Catalina on my MBP with AMD Radeon Pro 560 4GB and it runs well.

    Thanks so much for the feedback, it's so helpful 🙂
