            Bug ID: 84570
           Summary: Borderlands 2: Framerate drops dramatically with
                    dynamic lighting activated
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: kai at dev.carbon-project.org

Running Borderlands 2 with the option "DynamicLights" set to true, causes
constant frame rate drops (GALLIUM_HUD=fps shows ~30 as the usual lower end,
when there are many new objects, it drops to single digit numbers), when new
objects come into the visible area, ie. you see a new enemy or a team mate is
running into your LOS. After a second or so, you're back to ~40-60 FPS.

I'm seeing this on (Debian testing as a base):

But according to Aspyr (the developer of the Linux port), this is also a
problem with the Intel driver (see
therefore I selected Mesa Core as the component.

Let me know, if you need anything else to debug this.
