Bug #: 42117
Summary: r200 driver performance, ums, all mesa versions from
7.6
Classification: Unclassified
Product: Mesa
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/DRI/r200
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: majkell10@interia.pl
With disabled ModeSetting, performance in some 3d applications drop almost to
zero.
glxgears runs flawlessly,
few maps in openarena is unplayable,
extremetuxracer is unplayable.
oprofile with tuxracer:
CPU: Athlon, speed 1399.45 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Cycles outside of halt state) with a unit mask
of 0x00 (No unit mask) count 100000

I've tested almost all mesa versions from 7.6 to 7.11, unsuccessfully. With
mesa 7.5 all works great. Mesa 7.6.1 compiled with folders radeon and r200
copied from 7.5.2, also works great.
