Summary: Gallium R300g - xscreensaver "endgame" hack runs much
slower than under classic Mesa.
Product: Mesa
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r300
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: rankincj@googlemail.com
Using Mesa from git and Radeon 9550 (RV350). Under "classic" Mesa, the
"endgame" OpenGL hack from xscreensaver runs at between 15 fps and 20 fps.
However, it only runs at between 3 fps and 5 fps under Gallium. The CPU load
under Gallium is considerably higher too.

This is with vanilla Linux 2.6.33.1, libdrm-2.4.18 and xf86-drv-ati from git.

The glschool screensaver behaves similarly (when invoked from the command line
as a standalone application):
Classic Mesa: Load ~40% and ~30 fps
Gallium: Load ~50% and ~25 fps
This screensaver is in package xscreensaver-gl-extras-5.10-6.1.fc12.1.i686

Hm. It hits the immediate drawing path a lot. Changing the immd threshold from
10 to 6 fixes the colors, but slows down rendering even more. This probably
warrants further examination.

Renaming for easier finding.
Profile shows nothing out of the ordinary. We must be making bad decisions
somewhere else along the line.
