Pardon my ignorance, but I've found about batocera and I loved it in the few minutes I've played around with it. There's one thing that's been bugging me, I found no mention of dispmanx in the drivers which is said to reduce input lag by 1 frame compared to the default GL driver. Is it "off" in batocera? If yes, is it possible to "install" it? Maybe the openGL driver is now as fast as the dispmanx driver and that's the reason it's not there anymore?
