I've been observing a drastic drop in Figma's performance for some time now. To tell the truth, it's impossible to work because simply copying a frame takes a dozen or so seconds. I observe this phenomenon on both native and web app. I've cleaned the computer's cache, reset the Figma cache and it doesn't help! It looks really bad.
I'm very happy that you're adding a lot of new things, but I have the impression that you're omitting performance, which is the foundation. Please take care of the fundamentals

Hey
I’ve checked in with the team, and they’d like to take a closer look at this to better understand what might be causing the slowdown. Sometimes things like complex layer hierarchies or detailed vectors can contribute to lag, but we’ll need to review your specific file to know for sure.
I’ve just created a support ticket on your behalf — your reference number is #1383275. Someone from our Technical Quality team will be reaching out soon to help dig into this further. Please share your file link with support-share@figma.com invited directly as an editor (this won't affect your billing at all).
Thanks again for flagging this!
