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.
Video showing the issue:
-RX Vega 56/Ryzen 1700
I can confirm the same experience using a Radeon R9 285 with the Mesa 18.2.* series. The game for the most part runs really smooth but as soon as I reached the bunker shown on James B's Youtube video the framerate dropped greatly and no matter how low I set the graphic settings it made no difference.
