Mario Sports Mix runs slow

[Korados]

Hello,

yesterday I tried to play Mario Sports Mix (PAL) after some years. I used Dolphin 5.0-6245. I usually have the internal
resolution set to Auto, and it always used to run smoothly but now it runs extremely slow when the resolution is
set to Auto. I have to set the resolution to 3x Native to get the game running properly. I guess the hybrid XFB causes this. It's not a big deal, but
can I do anything to improve the performance while the resolution is set to Auto?

Thank you for your help!

In the past, were you using Auto (Window Size) or Auto (Multiple of 640x528)? If the former is fast but not the latter, I don't think there's anything you can do in recent version of Dolphin other than setting an appropriate resolution manually.

I used Multiple. Okay, thank you for the information! I was just confused that the game suddenly played so slow
after it always worked flawlessly for years.
