Some days I have a lot of lag on the usamune rom (but not the regular one) on PJ64 to the point that it's unplayable and some days I don't have any.

Does anyone know why or how to fix it?

hmm... do you have anything running other than pj64 on your PC while you have usamune open?

that would make sense why it's bad some days, good others.

Do u think that could be a problem with your rom setting?

Thank you for your answers. I don't have anything else running that I am aware of. The settings are the ones recommended in the document.

I had issues with interpreter mode, and recompiler mode works fine for me. try that. if that doesn't work, consult the usamune discord. it's there is the resources page.
