Monkey Island 3 works pretty slow with Wine 1.1.0.

It happens only in complex locations, where there is a waterfall etc.

COMI works very slow, even on my Core2Duo 2.53 GHZ (which is pretty good for
that game I think).

The strange thing is, when the screen is scrolling (eg. the character moves to
the other part of the scene and the scene is scrolling) it work properly. When
the scene is static (eg. no scrolling, only animated parts like waterfall or
rain etc) it works very bad.

In this demo you can see this when you are shooting with the cannon. A part of
walkthrough (on how to get to the cannon):

After the intro you'll find yourself captive in LeChuck's ship. Start talking
to the  small pirate and you'll realize that it's your old friend Wally. Make
him see that he is no good as a pirate and he will soon drop his  hook and
start crying. Pick up the  plastic hook from the floor and pick up the  ramrod
from the wall. Use the  cannon and sink the four boats full of skeletons.

Thanks
