As I told, I've started to play with optimus under F22. It is definitely more promising than was years ago, at least I can start everything but 3D apps which is in my case is not so frequent, however ideally everything should work fine (intel for my normal x session, and on-demand nvidia when I need this power)
I've used the following guide with bumblebee nvidia proprietary driver https://fedoraproject.org/wiki/Bumblebee#Fedora_22
Everything is fine except nvidia is still ON 12:52:37]vlad@tohuvabohu ~]$ cat /proc/acpi/bbswitch 0000:01:00.0 ON
When I start glxgear, I'm getting this

Anyone of you running successfully optimus/bumblebee on F22?
