When I was testing the recent builds with another PC with AMD phenom X3 B75 and Radeon HD 5450, the menu was going too fast regardless if I toggle fast forward or not, and the games are not affected by this. I had to set limit fast forwarding speed to on with 1.0x which means I can’t toggle fast forward on the games. Before that, the menu was going around 888 fps, making it almost impossible to control the UI.
Also, I don’t know if the issue has been fixed on the android with I was testing the latest version and builds from few months ago. When you use retroarch and when you finished using it, you don’t have audio, which means you can’t listen to music or some apps won’t have audio. The videos on YouTube and video players won’t load at all and so e apps would crash. It still happens if you force stop Retroarch from running, and I have to hard reset the system to fix this.
