------- Additional Comments From rainer.groesslinger@gmx.net 2005-16-07 07:02 ------- Just wanted to add my observations to this topic: Heroes4 runs fine (no sound stuttering etc. when the mouse cursor isn't moved or any other "active" animation happens [like riding with your hero], CPU usage goes up from 20% to 100% on my box then) - it also runs fine when when you move the mouse on the right side of the screen, so this slowness (and the resulting sound stuttering) is related to the drawing of the map screen - but you probably already know this :)
I am also flooded with the debug message fixme:bitblt:X11DRV_BitBlt potential optimization - client-side DIB copy
Situation didn't change with Wine 20050628.
