[continued from first post] is a location in the game where I get severe
performance drops making the game unplayable. I have attached a save game so
you can try it out for yourself. Just enter the building and let the attack
commence.

Running on Linux Mint 17.0 in case that's relevant.

I don't have this game, can you restest this game against 1.8 or 1.9 series of
wine or wine-staging 1.9? Also if you test wine-staging it has a patchset
called CSMT enabling it could help.

I just retested this with Wine 2.0 and it's hard to say whether this bug is
still present because I'm testing from a new (and more powerful) machine.

Nevertheless, FPS seems to drop from about 55 to 25 or so during the battle in
the building. It's not completely unplayable but I'm pretty confident I would
be getting 60 FPS+ with this rig on Windows.
