You are right - I used primusrun for my games for quite a while, until
optirun gained support for it. The advantage of optirun is that it can
bumblebee knows it's socket path and the path's to the NVidia libraries
etc., so it can set the correct environment variables for primusrun,
depending on bumblebee configuration and whether nouveau or NVidia are used.
Actually, optirun could use primusrun without calling the primusrun
script - I do not know why it does not do that.
Kind regards,
Ralf
