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@lists.freedesktop.org
Reporter: k...@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):

libclc: Git:master/5b48f170c8
DDX: Git:master/fbf575cb01 + Patch from
<http://lists.x.org/archives/xorg-driver-ati/2014-August/026534.html>
But according to Aspyr (the developer of the Linux port), this is also a
problem with the Intel driver (see
<http://steamcommunity.com/app/49520/discussions/0/616189106749909144/#c616189742697847998>),
therefore I selected Mesa Core as the component.
Let me know, if you need anything else to debug this.
