I did do a search ;), but only found stuff for dk1 :(

just got dk2, and the movement speed when moving the view is way to much, normal mouse movement is fine though.
keys do the same...

any way to reduce it?

Use the F1, F2 or F4 views. Use the keys above the arrow keys to adjust the camera further. Me, I run in constant max-zoom F4 mode. Better overview that way.

There is an option under gameplay to change the scrolling speed.

i think i had it on min, anyways i just toughed it out to completion :D
