[2020] When I turn on multi-sampling the game crashes at start. [Linux]

You will be using Wayland. If you switch to Xorg the crash won't happen.  

Hmm, that is weird ... I guess it's something to do with this Prime thing. Does it run on either video system okay without that?  

Less than say 40? Or still above that?

And, that is on either set of video hardware?  

I see. Aside from the raw fps number do you get any gameplay problem at 60fps? Because that seems pretty decent in its own right ... !
