Hello everyone,
We have been working on a series of pixel fonts for a customer for some time now (don’t ask! 
). This ranges from 9 pixel versal height to e.g. 30 pixels.
We are currently working with M1 Macs (16 GB Ram). The design of the individual letters is not a problem, but the kerning process is very, very slow if more than 20-25 words are displayed in the editing window on average. Fonts with a pixel hight above 20px are quite slow, because there are more pixel-components shown at the same time. For a text window with e.g. 370 words, typing a single letter takes about 4 seconds. Any changes to the kerning values takes quite long, too.
Each pixel is a pixel component, just as described in the tutorial on creating pixel fonts. In our case, for example (26px versal height), the letter “O” consists of 192 pixels.
Under View, everything is tuned off (Background, Guides, Metrics). Turning off „Metrics” helps a little to gain speed. All Plugins are temporary turned off (when starting Glyphs) for a test.
I assume that the display cannot be accelerated, can it?
Has anyone had any experience with extensive pixel fonts or tested something similar on an M2/Pro? I would be interested to know whether there is still a performance increase here.
Thanks a lot,
Thomas
