Citra slow until settings changed (SMT IV:A)

After loading a file or sometimes when entering a new area, the game starts running at 75-90% speed. However, after changing the resolution from 2x to 1x it goes back to 100%, and stays at 100% even after returning to 2x resolution. The same thing occurs when changing the texture filter to or from any option.

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.

^ This driver is out of date, to update, download (direct link) from Download Intel® Graphics Driver for Windows* [15.40]

Then follow this guide to install it:

Furthermore, enable Shader JIT in Emulation>Configuration>Graphics>Advanced Tab.

If that doens’t fix the issue, also try disabling your texture filter, then restart your game. Let us know if this solves the problem.
