Citra not running at 100% speed

Issue:
Yesterday, I was able to play Pokemon Alpha Sapphire just fine. I was getting 30 FPS and 100% speed. When I launched the game today, it started to lag. I was getting 25 FPS and and the speed was 75%-85%. I tried Ultra Moon as well, and I was having the same issue. Any solutions?

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

  • Due to AMD’s poorly optimized OpenGL driver, you may experience slowdowns.

AMD’s OpenGL drivers kind of murder performance in Citra. You can try disabling Hardware Shaders in Emulation>Configuration>Graphics>Advanced Tab to see if it’ll improve performance, but this is a bit hit or miss with some games on AMD GPUs.

You’d get a lot better performance on Lunix’s AMD OpenGL drivers, though you should only attempt setting up a dual boot for this if you know what you’re doing.
