Summary: CRUISE: Slow / unresponsive game behaviour

Initial Comment:
Problem: The gameplay of the ScummVM version feels too slow, especially when comparing the game to the original (DOS) version or other ScummVM / cine games. This is especially notable when moving the mouse: It seems the cursor is updated only a few times per second, resulting in a very choppy movement.

Other examples:
1. Judging from the Delphine logo in the beginning and a few animations during the game I would say the game is about 25% too slow on my PC.
2. Character animations look okay, but the original DOS version also seems a bit smoother (probably also those 25%).
3. Probably a different problem, but when clicking on a locked door, the complete game (animations, mouse cursor movement) hangs for a few seconds.


The ScummVM process takes only about 10% CPU time. If it's preferred to split the above examples into separate tickets I can do so.

Tested versions: ScummVM 1.3.1 and git snapshot from 15.10.2011
Platform: Linux (Slackware64 13.37)
Version: Cruise for a Corpse from Classic Collection, German CD version
CPU: Intel Core i7, 4x2,8 GHz
