            Bug ID: 94835
           Summary: Increase fragment shader sample limits from 16 to 32
                    (AMD Linux - Mesa/RadeonSi)
           Product: Mesa
           Version: git
          Hardware: All
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: esmith@feralinteractive.com
        QA Contact: dri-devel@lists.freedesktop.org

Please increase fragment shader sample limits from 16 to 32. This is causing
serious issues with Company Of Heroes 2 as the engine needs more than 16
samplers to correctly render the floor.

Please note: Mesa support 32 samplers with their Intel drivers, but not AMD.
See GL_MAX_TEXTURE_IMAGE_UNITS_ARB in
https://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html

Feral can provide a Steam key to active Mesa engineers working on this issue if
that would help their progress. YOU should be abel to use Intel Mesa as a
reference as that draws correctly as it has a higher texture sampler limit.
