Threads seem to run at reduced speed in Pyxel (proportional to FPS)

[dskill]

First off thank you for this amazing game making tool.

I'd like to use it to with some educational LLM/audio generation game experiments, but I noticed that the FPS of pyxel seems to have a very direct impact on how long it takes to execute calls in a thread.

For example, I'd like to run

response = openai_client.chat.completions.create(
            model="gpt-4o",
            messages=messages,
            max_tokens=30,
            temperature=0.7)

in a thread, so that I can get an LLM result back without blocking pyxel's playback. However, if I do that, I have noticed that the time it takes to get a result is very slow (and roughly proportional to the fps I have pyxel set to).

Do you have any advice on how to run threads at full speed in pyxel? Thx!
