Optirun/primusrun question

Is optirun -b primus the same as primusrun?

Bumblebee is the current workaround for using Nvidia optimus with linux.

At the heart of bumblebee has been VirtualGL which is now being superseded by Primus.

If you have Bumblebee you’ll know that to use your discrete card you need to invoke optirun application from the command line and then after a short wait your application runs using the VirtualGL backend.

Unfortunately the VirtualGL backend does not play nice with some applications, particularly Wine and Crossover.

Primus is the replacement of optirun and it all it means to the end user is that instead of using optirun you now invoke an app with primusrun application.

The developers of Bumbleebee highly recommend primus over VirtualGL because there are a host of benefits.

One benefit is that it works perfectly with Wine and Crossover meaning You can play your Windows games on your discrete card instead of having to use your integrated one and has substantially better performance too.

I know that, the virtualgl stuffs is equivalent to optirun -b virtualgl, I’m asking if specifying -b primus makes it the same as primusrun

I should RTFM more before asking, my apologies

No need for apolgies. There are no unnecessary/stupid questions, only unnecessary/stupid answers. Other users might benefit from your question, if they also miss some manuals/guides during research.
