Pokemon Y unstable speed(%) and fps

Noob inquiry: played several minutes worth of gameplay, and I’ve generally noticed the lag due to unstable emulation speed ranging from 60-90+% along with the FPS increase/decrease that goes with it. Any way to fix this?

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

  • Due to AMD’s poorly optimized OpenGL driver, you may experience slowdowns.
  • Please enable the Vsync option if you are experiencing screen tearing.

This sounds hardware specific. You can try disabling Hardware Shaders in Emulation>Configuration>Graphics>Advanced Tab. This sometimes improves performance for AMD GPU users. Other than that, Linux might be the only other way to get better performance. The OpenGL drivers AMD has on Windows are just that bad.
