Is it only fast on MacOS? I tried it on Linux and it was unusably slow. Seconds per frame instead of frames per second.

I’ve been using Zed a few months on my fedora laptop (thinkpad x230) and haven’t had any performance issues. Definitely faster than any other graphical editor I’ve used. Perhaps a driver issue would be slowing it down?

  Maybe, but no other application or editor has this problem. If all other apps work but Zed doesn't then it sounds like a Zed has an issue. EDIT: just gave it a shot and I get "unsupported GPU" as an error, informing me that my GPU needs Vulkan support. Their detection must be wrong because this is not true. And like I said, other applications don't have this problem.

    The microcosm of a linux user played out so fast in that thread :P

    You should report an issue with your specs, not just say “other applications don’t have this problem” — especially as a Linux user. For one, not all applications are GPU accelerated. Two, their UX may need to be improved for a specific hardware configuration. I have used Zed with good performance on Intel dGPU, AMD dGPU, and Intel iGPU without issue — my guess is a missing dependency?

      Meh, it's not worth the trouble. I don't care enough about using Zed to fix their Linux distribution problems or debug something for them. This isn't some volunteer backed FOSS project where they get a free pass or free QA work from me.

        What's the point of commenting that it's slow if you don't care about using the program and switched to something else? Also, how is whether the project is volunteer-run relevant? Would you file a support ticket for commercial software you use saying "it's slow" and then when they follow up asking for details about your setup, you say "sorry, you don't get free QA work from me"? Do you really think that would lead to them fixing your performance problem?

        There is great enthusiasm for the editor in this thread. A personal anecdote indicating subpar performance on a common developer environment (Linux) is a useful signal that took a few seconds of effort. Putting together a high quality, actionable bug report is a much higher bar that can often feel like screaming at the clouds.

        It seem like bickering at this point, but I do not see how that is a useful signal. I’m genuinely curious what you are getting out of it
        0cf8612b2e1e 1y ago
        So, only positive feedback allowed in this thread? As a Linux user, I am sadly accustomed to some software working in only a just-so configuration. A datapoint that the software is still Mac first development is useful to know. Zed might still be worth trying, but I have to temper my enthusiasm from the headline announcement of, “everything is great”.

        Is it even Zed’s fault if your linux system/setup over-eagerly prefers cpu rendered graphics because of old political and religious driver licensing issues?

    I had the same issue with my nvidia gpu but resolved it with the fix in this thread: https://github.com/zed-industries/zed/issues/14088 https://github.com/zed-industries/zed/issues/14088

I'm under Debian and i3wm/X11, sometimes it does some stuff that blocks input for a while so I can't drive the window manager until its done. At least it did a month or so ago, and at that time I couldn't figure out a practical use for the LLM-integration either so I kind of just went back to dumb old vim and IDEA Ultimate. When its fast its pretty snappy though. I recently put revisiting emacs on my todo-list, should add taking Zed out for another round as well.

  I think that’s the same issue I’ve had with i3 and the sole reason why I switched to bspwm. I think it happens when the cursor is on a GPU accelerated window and you quit the app - it’s like i3’s keyboard input gets trapped in that pane and can’t escape (my work around was to create a terminal and kill the GPU app with skill using my mouse)

it's not even fast on macOS in my experience

  That's interesting[1], what was slow when you tried it on MacOS? [1]: people experiencing sluggishness on Linux are almost certainly hit by a bug that makes the rendering falls back to llvmpipe (that is CPU rendering) instead of Vulkan rendering, but MacOS shouldn't have this kind of problems.

Linux user here. I find Zed lightning fast compared to VSCode.
Palmik 1y ago
No issues on Linux for me. Much better (faster / snappier) than VS Code and forks.
littlestymaar 1y ago
That sounds a lot like a CPU fallback of the rendering that should otherwise happen on the GPU. Isn't there any logs that could suggest that this is the case? Edit: I just saw your edit to your reply here[1] and that's indeed what's happening. Now the question is “why does that happen?”. [1]

I ran into the same issue (software rendering), pushed through to get it working, and it was worth it. It is extremely fast. I'm on PopOS and the issue ended up being DRI_PRIME. Might be worth trying `DRI_PRIME=0 zed`.

Is it only fast on MacOS? I tried it on Linux and it was unusably slow. Seconds per frame instead of frames per second.
