I'm not sure, it might have changed since, but my personal experience was different. Tried using zed on Linux (pop os, Nvidia) several months ago, was terribly slow, ~1s to open right click context window. I've spent some time debugging this, and turns out that my GPU drivers are not the best with my current pop os release, but I still don't understand how it might take so long and how GPU is related to right clickin…
I will keep playing around with it to see if it's worth switching (from JetBrains WebStorm).
