Bug ID: 97340
Summary: POSTAL 2 poor performance at certain times, RadeonSI
driver
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: webexamples@exemail.com.au
QA Contact: dri-devel@lists.freedesktop.org
I have a Radeon R7 370 and running Mesa 12.0.1, I get horrible performance in
certain areas or events of POSTAL 2, to the point where the game is almost
unplayable.
This issue is easiest to reproduce on the level with the bank. Approaching the
bank causes the framerate to get lower and lower, and entering it causes the
game to immediately freeze for several seconds. If you rob the bank, the
resulting firefight will cause the game to freeze repeatedly.
Using the exact same hardware, I've played the game using fglrx with much
better performance. Help would be much appreciated.

GALLIUM_HUD graphs for the scene
I can reproduce this on VI.
According to GALLIUM_HUD, the frame drops correspond to shader compilations.
apitrace profiling shows the slowest calls are glDrawRangeElements, many of
which take over 80ms (!). The calls don't use any user shaders so the
compilations must be for internal shaders generated by Mesa to implement
fixed-function functionality.
Trace:
http://constexpr.org/tmp/POSTAL2-radeonsi.2.trace.xz (73 MiB)
Not sure if there is a good way to fix this (besides making the shader compiler
faster). Maybe there could be a lighting super-shader that can be used while
more optimized variants are compiled.
Kernel: 4.7.0-gentoo
Mesa: git-a73116e
LLVM: r278309
GPU: R9 380X
CPU: FX 8350

It seems that this situation has been improved somewhat on Mesa Git in the last
12 hours. The freezes are still there, but they're shorter and less frequent.
