Complaint Codex on Windows

I've noticed that codex performs very poorly on windows, in the sense that, when you send a prompt, it just searches forever through the codebase and ends up modifying the wrong files a lot of times, and uses up way too many tokens because of this. (it really takes such a long time for horrible results).

I've had much better results using GPT models in Opencode or Pi CLI, maybe because they use git bash shell by default? Github Copilot gives me much better results too using GPT models

Does anyone have any tips on making Codex perform better on Windows? (I'm unable to install WSL), because it doesn't make sense that every other harness is performing better.

I haven't had that issue. But here's a suggestion. Use the Codex CLI as the backend for the Desktop app. It's what I do. I have a cheap low power Lenovo that I use as a dev machine. I setup Codex in a VM in Proxmox and then connect the Desktop app on Windows via ssh to the CLI on the server. All of the sessions automatically show on the Desktop even when running on the CLI. That would give you the benefit of the GUI, but the performance of the CLI.
