I did a slightly more scientific test today with __GL_THREADED_OPTIMISATIONS
(running with the zerg) and aimed for watching for the lowest my FPS got. 
Luckily, the zerg was actually quite large today - large enough to drop me to
the lowest FPS I ever really hit.

Note: This is with all console output disabled.  I did notice a massive amount
of extra output when running with WINEDEBUG=fixme-all the very first time I ran
the game with these flags, and I don't think I even bothered to get past
character select because I know how much of an impact console output can make.

With those flags: I saw it drop to 8 once or twice, usually stayed at 10+
(during the massive action sequences, I averaged about 12).
Without: I saw it drop to 4 once or twice, usually stayed at 8+ (during the
massive action sequences, I averaged about 10).

Conclusion: +5 is actually optimistic - it looks like we should expect +2 on
average.  This test still isn't comprehensive, but at least suggests that Guild
Wars 2 gains something from it.

I also noticed the numbers fluctuating a bit less with the flags enabled.  As
mentioned, I saw numbers as low as 4 for short periods *without* threaded
optimisations enabled, even though it was normally sitting around 9 or 10;
*with* them enabled, I never saw a number lower than 8.  Stuttering (rare
split-second pauses) also seemed less frequent with threaded optimisations, but
I wasn't timing it - so I could easily be fooling myself.
