So, after months of hoping for better performance on my Mac, thanks to Neuro… No Neuro I found out what caused my issue:
Having set my Mac display to the “iMac” color profile in the OS settings, I have a terrible refresh rate of Renoise’s UI. To the point, where I deem it unusable. Approximately 20 fps.
Solution: Setting the display color profile to sRGB IEC61966-2.1
Thing is, if Renoise can be “fixed” to work well with any color profile, I could keep using the one I work with for editing photos, without having to switch every time.
Renoise version 3.3.1
System: Intel based iMac 2017, 27" model
MacOS 11.1 Big Sur
