            Bug ID: 97879
           Summary: [amdgpu] Rocket League: long hangs (several seconds)
                    when loading assets (models/textures/shaders?)
           Product: Mesa
           Version: 12.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Other
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: s.jegen at gmail.com

The game Rocket League has recently be ported to Linux (still in Beta at the
moment). Running the game works fine but at each match start, the video output
just freezes for several seconds. After these 5-10 second pauses the game
resumes (though at a much later point in time since the other players in this
multiplayer game kept playing during the time the output froze on my end).

After the first few of those freezes, they don't happen anymore for that one
match (presumably because the textures/shaders have been loaded already?). As
soon as players join or leave those freezes come back though (because more
loading of assets is required?).

Setting the "Texture Detail" option to "Quality" instead of "High Quality"
reduces the freezes to around 1 second max which makes the game much more
playable.

Hardware:
i7 3.4GH, 8GB RAM
RX 480 Sapphire Nitro 8GB

Software:
Linux 4.7.4-1-ARCH #1 SMP PREEMPT Thu Sep 15 15:24:29 CEST 2016 x86_64
GNU/Linux
mesa 12.0.3-1
llvm 3.8.1-1

I tried to get an apitrace of a match vs CPUs. You can find it here:
