Am experiencing similar problems on my 1 Ghz machine, 512 Mb memory, GEForce2 MX w/latest nVidia driver, DirectX 9.0b, and latest Divinity patch installed. After about 1 hour of game play, I notice that all sound effects and music begin to echo and at the same time my character begins to move more and more slowly. When this begins to happen, unless I save the game, exit the program, and reboot, Divinity will eventually crash. Incidentally, I have never been able to configure graphics to run at anything higher than 800 x 600 resolution without Divinity crashing.
