I can confirm this on a Q6700 (4x2.66 GHz) and Nvidia GTS 250.

I did some testing with oprofile (even built wine with debug-information) and
this is what I ended up with:

- Windows (XP) uses all four cores up to 80% while playing, gives me 65+ fps
(including dynamic shadows)
- wine (1.1.35 gentoo) uses exactly ONE core at 100% and gives about 12 fps (no
dynamic shadows)
- from what I could read, most of the time is spent mutex-locking in kernel and
nvidia drivers.

No idea why borderlands doesn't use multicore in wine :-/
