I tried it out and couldn't reproduce the difference on my machine. Are you
using a composite manager? I'm using Ratpoison which is a quite minimal window
manager so perhaps that is where the difference lies. However, a couple few
things that may be confounding your results:

1) Loading nvidia-settings when running in a different XServer? 

You might not get the same settings if you don't do this. I lost my AA and
VSync settings which could account for some performance differences (although
unlikely of the magnitude you found)

2) What are you using to track FPS? If you are using WINEDEBUG=+fps, you'll
find that your FPS will jump to double what it was before once you switch back
to your main xserver. However, you should see a string of lower fps counts
before it jumps which will indicate the real FPS.

Anyway I'm betting it's a composite manager issue. In my case I do get a larger
FPS decrease with Witcher 2 than in other games, but I'm not sure it's outside
of the normal range. I.e 40-45% of windows with Witcher 2, vs 50-65% of Windows
with other games. I think because I am GPU limited it may be causing additional
issues with Witcher 2, though.

BTW the threaded optimisations only makes a small difference for me with this
game, although it makes a large difference with some other games, like the
Witcher 1.
