Citra lags when running fire emblem fates only

The speed is as low as 38%, FPS 11 when I am running this game only. However when running other games eg fire emblem awakening and omega ruby it works fine.

I ve tried below:
-set internal resolution to native
-untick hardware shader
-untick shader JIT
-prioritizing citra in PC control panel

Please help me, thanks in advance!

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.

You should definitely re-enable Shader JIT. Disabling that just leads to crappier performance.

Regardless, the main issue here is your AMD iGPU. AMD has incredibly bad OpenGL drivers on Windows. To the point where you’d get around 3x better OpenGL performance on Linux. Its just that bad. There’s not much we can do about that unfortunately.
