Today a macOS user managed to improve Krita’s performance to “very smooth” level by just disabling Canvas Graphics Acceleration. We both think the quality loss and occasional slowdowns to be acceptable – much better than the unbearable constant slow canvas performance when CGA was ON.
Krita macos slowdowns tend to happen on machines with Intel integrated graphics. Every macbook I had my hands on, old or new, were all so slow to the point Krita was unusable (at least to me). Although there was another user reported that it was fast on macOS mojave on a macbook air from mid-2015.
I don’t know if you know about this, so I think I should relay the information. Maybe if you can make it work too, we can write this into the FAQ so more macOS users can benefit from this.
I tried turning off CGA under Linux, it was also surprisingly fast, and I didn’t notice much quality loss, only occasional slowdowns. It was totally usable.
Is there any other limitations when the CGA is OFF? Do you think I can suggest macOS users to turn off CGA as a solution for their solowdowns? Thanks!
