Nomnomnami games aren't heavy are well made are short and most of his game uses the game making app that joiplay support so it always works for his game also I am pretty sure you tried to play games that have nothing to do with joiplay intended use to get an experience this bad just look at joiplay list of supported games it works way more than you say (except if you installed the plugins for joiplay in this case I agree because for some reason it work less with them)
