Codex Fails on Windows/Linux

Dear OpenAI Developers,

I need to raise a serious issue today.

I have always used Codex on my Mac, but today I decided to try it on my Windows PC through the official VS Code extension. It worked for a while, but after I closed VS Code and opened it again, the extension became completely stuck on the logo screen.

There was no error message, no warning, and no explanation. I waited for more than half an hour, but nothing happened.

I then downloaded the Windows desktop client. As soon as I opened it, it used more than 70% of my system memory. Even after I finally managed to get into the app, it was so laggy that typing a single sentence felt difficult.

My Windows PC has an Intel i7-14900 processor and an RTX 4060 GPU. I do not consider this outdated hardware, so the performance was honestly unacceptable.

At first, I thought the problem might be related to my Windows setup rather than the extension itself. To test this, I installed VS Code and the official Codex extension on my public Linux server. Unfortunately, I experienced exactly the same problem. After another half hour of waiting, it was still stuck on the logo screen.

I am genuinely looking forward to future updates and improvements because I am a loyal user and a big supporter of OpenAI. On macOS, it feels like you release updates almost every day and continue making the experience better and better.

However, after leaving the Mac environment, I realized that the Windows client and VS Code extension seem to receive nowhere near the same level of optimization. The difference is honestly unbelievable.

I sincerely hope you can give a proper response to a loyal paying customer and explain whether these issues are being addressed.

You are welcome to discuss Codex issues on the forum, however the official place to report and track them is the GitHub issue tracker for OpenAI Codex.

I had ChatGPT look for the closest related issue and it identified:

If that issue matches your problem, consider adding a :+1: reaction on the GitHub issue page itself, not just on the forum topic, as reactions on GitHub help the developers gauge impact and prioritize work.

If it is not the same issue, try searching the existing GitHub issues for a closer match. If you cannot find one, then open a new issue with as much detail as possible.

Thank you for the detailed report and for your patience. A fix was rolled out today that should address these issues.
