            Bug ID: 108270
           Summary: [proton] Wolfenstein: The New Order (frame rate issue)
           Product: Mesa
           Version: 18.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: lejimster at gmail.com

In the first bunker the frame rate drops heavily and stutters in spots, the
frame rate is perfect 60fps before and after this area.  I tested the same area
on Windows 10 and also Ubuntu with proprietary drivers and they don't suffer
from this issue.  

Tested using Proton 3.7-6 as the game needs a patched wine to run. Hopefully
the trace is long enough to see the issue as the frame rate drop doesn't always
happen immediately.
