yeah, lakka is at amazing state rn, you can also try this little neat thing gavin added recently... Edit your uenv.txt (its like a config for lakka's kernel), there's a performance mode line, turn it on by switching it to 1. It will change the standard cpu governor to performance governor, i've tested some gc games and it actually makes some difference, it does give you a slight performance boost.
...anyway, yeah, lakka has come a long way, there's also a working moonlight core with hw decoding which performs very well (on par with HOS port by Xitrix delay wise), tho its not as feature rich as xitrix's port and it doesn't work with gfe (or afaik it works with older versions of gfe, but im using it with sunshine, works great)...i can't remember the last time i used HOS for emulation since gavin started bringing lakka to life... I rarely even use HOS anymore.
