Steps to reproduce
open a note with a bunch of links/content in live preview
live preview would not be laggy.
live preview is noticeably laggy when 1) scrolling 2) typing.
with a note like this (attached at the end) that has a bunch of links, obsidian lags pretty severly in live preview. i checked devtools performance tab, and it is somewhere between 12-24ms each keypress. not unusable, but definitely noticable. i have an ASUS FX502VE gaming laptop, obsidian does run on hardware acceleration, however not on my nvidia GPU (overkill & drains a lot of battery), it runs on intel HD graphics.
i don’t think the gpu is the problem honestly, it more seems like live preview is not so well optimized - each kepress event calls some sort of an
e.update function, which (i assume) updates elements, this is the culprit, taking somewhere between 9-12ms each keypress.
i know this is not an issue for everyone, because a lot of people have overspecced MacBooks, but i don’t think obsidian, an electron app, has any business running this poorly on a gaming laptop (albeit a few years older).
i would be glad to see more optimizations done in live preview - maybe virtualization (don’t render or update anything that’s not on screen) and some other types of optimizations too.
lastly, this is only prominent in Live preview. source view is fine and so it reading view. i have a 165hz 1440p monitor, if this info is needed. I have tried the same note in sandbox vault and the lag is still 80% there (still noticeable).
