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

  • Due to AMD’s poorly optimized OpenGL driver, you may experience slowdowns.
  • Enabling Accurate Multiplication is recomended in certain games. If you are experiencing graphical glitches, try enabling this option.

See Citra keep crashing upon lloading game (MHXX)

For low fps problem in MH4U, update the game to v1.1 then you can use the codes on this page to improve performance:

You have the game update if the icon looks like this in your game list in Citra:
It will also say v1.1 on the title screen in-game.
