            Bug ID: 101278
           Summary: Severe slowdown on Shadow of Mordor between 17.1.0 and
                    17.1.1
           Product: Mesa
           Version: 17.1
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: nagrigoriadis@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

Shadow of Mordor slowed down significantly for me on my notebook between Mesa
17.1.0 and 17.1.1

My system:
Gentoo Linux 64-bit
Dell Precision M4700
Intel i7-3720QM quad-core
16 Gig RAM
AMD FirePro M4000 (Cape Verde, 512su, 1GB DDR5 RAM, 675Mhz)

I then did a bisect to find the commit where the slowdown happened (used the
built-in benchmark tool manually, some custom medium-low settings):
35ec26bb00536639b9571f31d8e3f2bcbcfc32fb 30.31fps
ad3b5b7f5f7590fd4359ea3483e2309e4cebc472 18.12fps

So the commit that causes the big slowdown:
https://cgit.freedesktop.org/mesa/mesa/commit/?h=17.1&id=ad3b5b7f5f7590fd4359ea3483e2309e4cebc472
seems to be specific to SI, but appears to fix an issue in tessellation.
I double-checked, and tessellation is off in the game settings, so I'm
surprised this caused a performance difference.
