Citra Nightly very slow on Surface Pro 4

Enter a description of your issue here, in full detail.

I tried playing The Legend of Zelda: A Link Between Worlds on my Microsoft Surface Pro 4, but I always end up getting between 5-25% speed, despite decreasing all of the graphical settings and ensuring that I have updated all of my drivers.

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

  • You are running out of date drivers for your GPU. You need to install the most recent driver for your graphics card from Intel’s website. Support for Intel® Graphics
  • Please enable the Vsync option if you are experiencing screen tearing.
  • The CPU Clock percentage is not 100%. You may experience unexpected game speed.

Go to Emulation>Configuration>General and hit Reset All Settings.
You shouldn’t need to touch any of the advanced graphics settings. Playing with them will massively influence the performance, and the standard settings are already set up for the best performance.
