I bought this game because dungeon siege 2 was my childhood...
Its been a struggle to make the game work on windows10 flawlessly, these launch options seem to fix:

fullscreen=false height=900 width=1600 maxfps=120 nospacecheck=true Tutorial_tips=false nointro=true

( No crashes, no sound lag, 1600x900 - you can maximize to 1920x1080 afterwards - but stil windowed )
