I did some more reliable tests, using the /timetest slash command and flying
from Seven Stars to Serpent Spine. This way all moving player/non player
characters are not rendered during flight, making the result more repeatable.

The game itself reports the min/max and average framerate after landing, no
third party tools needed.

For the first test I did the same run with the very same settings a few times.
The error of the measurement of the average framerate seems well below 1%
(maybe 0.5%), for the min/max fps the error is more, maybe 5%. So the min/max
values should be not compared between different tests.

                                                     min/max        avg
# __GL_THREADED_OPTIMISATIONS=0 wine wow -d3d9       10.0/52.0      39.3
# __GL_THREADED_OPTIMISATIONS=0 wine wow-64 -d3d9     9.3/49.8      39.1

# __GL_THREADED_OPTIMISATIONS=1 wine wow -d3d9       10.0/59.4      42.3
# __GL_THREADED_OPTIMISATIONS=1 wine wow-64 -d3d9    10.7/56.1      41.7


This looks like 8% gain in 64 bit mode and some 6% in 32 bit mode, where both
modes are exactly the same speed with threaded optimizations turned off.

I noticed the CPU usage seems to always be around 160%, no matter what, and the
total system load about 5% (which is 40% of a single core for a eight core
system).

The settings where the way I preferred them (not some not so realistic
everything off or all ultra).

Resolution: 1920x1200
AA:         4x
vsync:      off

Textures:   high
Anisotrop:  16x  (anything less makes my eyes bleed)
proj. tex.: on

Shadows:    good
Water:      medium
Sunshafts:  off  (forced by AA 4x)
Particles:  good (doesn't have much impact, but more and I get blind during
raids)
SSAO:      off  (forced by AA 4x)

Viewing Range: Ultra (not sure about translation)
Details:       Ultra
Objects:       Ultra

i7-2600 at 5Ghz, in this test running at about 4.8 GHz because only 2 cores were
idle, and GTX 460 at 750 Mhz running on nvidia-drivers-310.14
