I looking now on another task manager under Linux and see ~26% usage for ScummVM/Sword2.5, this is ok.
Sorry for this ticket, you can this closed.

Hi, I subscribed to this issue because I also found the game very lagging and with high CPU usage, and I can confirm it's still so on current git. CPU usage is 100% on a Core Duo on 32 bit Linux when doing just nothing. For comparison Broken Sword 1/2 are around 6-12%, while COMI is about 21% and are perfectly playable.

Those games ar uncomparable. Both COMI and Broken Swords 1&2 run on 640x480x8bpp, while BS2.5 is a 800x600x16bpp game, which is 3x more data per screen. Also at this moment BS2.5 does not have dirty rectangles implemented, so the redraws are pretty heavy. This is how the original engine was developed, and the graphics pipeline is implemented in the game scripts, so it would be not trivial to change.
Thus, unfrotunately BS2.5 will stay as a resouce-hungry game at this moment.

It would be nice to fix it before the release of 1.8.0. Raising priority.
