SNES Performance Issue: Slow Emulation

[RetroPl4yer]

Hi , I want to thank you for your amazing work on this project, it's truly impressive! I'm reaching out to share some feedback and report an issue that might already be on your radar.

I'm experiencing performance issues with SNES emulation. Here's what I noticed:

• On an older setup, SNES games run slowly.
• On a newer setup, I tested Super Mario World without frameskip, and it runs at around 40 FPS.
• Enabling software filters makes the performance even worse.

I checked SNES9X code and noticed it might be buffering tiles for reuse instead of recalculating them. Could this be why the current version is using so much CPU?

Thanks for looking into this!

Could you be more specific about the 2 setups ? Afaik it's supposed to run full speed on a 10+ years old desktop computer.
