I've been using it as a replacement for VSCode/Cursor for the past few months and really like it.
There have been recent changes to the font rendering, it now looks good on my 1440p monitor - when I first tried, it was blurry and instantly gave me a headache. It does seem strange to me that *font rendering* of all things is what a text editor has trouble with. Precise font rendering should be table stakes here.
As for performance/memory usage, it's been top-notch for me on both Linux and macOS.
I had originally switched to try and get away from Microsoft's "only focus on AI features" trend in VSCode, but it seems like Zed has fallen into the same trap.
