I currently use the 11-in MacBook Air in the early 2014 to run Glyphs and when I project my screen onto monitors with full HD (1920 * 1080) it starts to get quite laggy with around 25 frames per second when drawing fonts. It gets worse when I have two sentences of glyphs on screen.
I wonder how Glyphs run on different laptops. My Air doesn’t have individual graphic cards and it’s using the integrated Intel HD 5000 but it runs very smoothly when I don’t have it on a monitor.
Later I got an AMD RX570 and used it as an eGPU when I use my monitor. It runs much better but it can still be laggy. It lags a lot when I have the blur effect on for preview. I assume much performance potential has been swallowed by the Thunderbolt 1 port bottlenecking on my old mac because RX570 is quite powerful.
I wonder how Glyphs run on different mac models. I have used a 2017 iMac and it runs quite smoothly. Do you guys experience lag when you have 30+ glyphs on preview? I’m not sure how I could upgrade my hardware with least money since macs are pretty expensive. If the RX570 alone without bottlenecking from Thunderbolt 3 could bring the performance up then I could buy a second hand mac with Thunderbolt 3 port.
I’m not sure if CPU and RAM also being a big part affecting performance.
By the way, Glyphs performs better than Robofonts on my laptop.
