Not exclusively a UI3 topic, but I’ve seen major performance drops during this last year, another bigger one after switching to UI3.
My MacBook Pro i7 (2018) get’s to its absolute limits when I open Figma and run an MS Teams-Share at the same time. Stakeholders usually have even worse (Windows) Laptops with even more problems opening files, even though it’s readonly mode. My feeling is that until like 1,5 years ago (±) after a big feature rollout Figma may have had a worse performance for a few weeks or months but there was always a technical consolidation phase where features got streamlined and the whole app got (as good) as performant as before.
I understand that more (awesome) features mean we need more power but for me personally the biggest win and value provided would be better performance. Some KPIs for me would be:
- How long does it take to open a file / prototype?
- How long does it take to switch pages?
- How long does it take for Figma to be reactive again after minimizing / switching focus?
- How much CPU/GPU power do I need to not experience frame-drops while navigating / zooming big files / inserting components from a lib / inserting big media?
Thank you so much for constantly improving Figma <3
