Masive online lag

Issue:
So i am trying to play nsmb2 with my brother and when I create a room and joins as luigi there is some masive lag. but the thing is that me and my brother both have really good pc’s and offline both of us get 60fps with 4x native resolution. Plus, since it’s my brother, we are literally in the same physical room so I don’t know why it’s so laggy.

Here’s some issues I found with your log that might help.

  • Enabling Accurate Multiplication is recomended in certain games. If you are experiencing graphical glitches, try enabling this option.
  • You are using open source system files for Mii data. This will appear as your Mii having broken graphics, but will not affect the stability of the game. In order to resolve this, please refer to our guide on dumping system files. https://citra-emu.org/wiki/dumping-system-archives-and-the-shared-fonts-from-a-3ds-console/

I did what you told me @CitraBot but its still lagging when online. When offline, its smooth 60fps.

That didn’t solve my problem.
