Just regarding bumblebee, since 16.04 it is not compatible with Ubuntu anymore and is basically broken. We need to wait for the 4.0 release in order to expect anything usable. With 14.04 I played a lot of games via bumblebee and all worked without a problem, even for example Unigine engine tests etc. Without any tweaking or tuning and with a very good performance, comparable to Nvidia Prime (I have Nvidia 850M). So if bumblebee is a needed use case, I would recommend going back to 14.04 (at least until bumblebee 4.0 is released).
