Every update makes Citra slower

Issue:
Enter a description of your issue here, in full detail.
Citra used to work perfectly, but the recent dozen or so updates made it run slower and slower - the average (after version 1579) is now about 60-80% speed, this is starting to make it unusable.
I do have the latest update of my graphics cards driver and this log uses the optimum settings, anything else makes the emulator run even slower or crashes it.

Try turn off vsync in the Advanced graphics settings. I don’t know if you already did since it’s not logged.

Do you remember the last build that was “good”?
