TLDR: v1.10 = Perfect graphic performance on Mac Mini M1 v2.00 = Trash graphic performance on Mac Mini M1
When BS 2 first released, I tried it on Mac OS (M1 Mini). Orbiting an empty plate in Prepare and Preview yield very sluggish performance. I immediately downgraded back to v01.10.02.76.
I decided to give the newest versions a try this week (v02.00.02.57) with the same results. I have now reverted back to v01.10.02.76.
Same issue here on M4 Mac Mini ever since the 2.0 update. Every action inside the 3D viewport is sluggish. Even the mouse cursor moves sluggishly when it’s anywhere over the view even when Bambu Studio is not the foreground app. Returns to normal when I move the cursor to the sidebar.
It’s a Mac display resolution scaling issue. For me, anything more than 1920x1080 will cause the prepare workspace to be sluggish and borderline unusable like in your video. I have to resize/scale down the Bambu Studio app window or move it to one of my monitor that does not have scaled resolution enabled.
So the work around is to resize down your app window, or use a display resolution no more than 1920x1080 under System Settings > Displays.
