Witcher 2 - Max settings with Steam Play Proton (5.0-10), the Linux compatibility layer from Valve.

How well does the Witcher 2 run on proton compared to the OpenGL Linux Port on a GTX 970 ?
(See details in PC CONFIGURATION and TWEAKS below)

I've played and finished the Linux OpenGL port years ago when it was finally stable and the performance was between 45 and 60 fps with a mix of medium and high settings.
The proton version works way better between 60 and 100 fps at MAX settings (no Uber sampling)
