Slow performance graphics on Mac in certain resolutions – DSP and Plugin Development Forum
I did some measurements with the GUI performace on Mac. M1, VSTGUI4, Big Sur.
I noticed that the perfomance depends a lot from the ‘desktop zoom level’ of the OS which you can select in the system settings.

– If you select ‘more space’ (100% zoom) performance is fast. Graphics are crisp.
– If you select ‘larger text’ (200% zoom) performance is also fast. Graphics are crisp.
– If you select a zoom level in between (like 150%) GUI performace is a lot slower. Graphics are a bit blurry. The difference is quite noteable on the M1 mini with a fast 4K screen connected.
It seems they first stretch anything up for 300% and then downsample it to 50%. This does seem to affect all(?) software.
