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.
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?
