I have a problem with Dungeon Keeper 2 gameplay. At the main screen when I switch between options, movement is slow and with breaks, as if it is set to software acceleration mode. When I choose hardware acceleration nothing changes. If I leave and return to the graphics option tab "Hardware Acceleration" is deselected.

In the game all graphics are distorted and no gameplay can be achieved.
Any idea what to do to fix that? GoG didn't provide an outside configuration tool with that one.

The DK2 game forum on GOG is more likely to have a bigger group of people that can solve your problem before it gets buried. If you've tried there, then carry on.

I can't find any DK2 forums. There is only a DK1 forum.
I you have a link, please share.

Same forum. GoG's been a bit slow on updating forum titles.

That's the one. They have a habit of taking some time renaming subfora when they add an additional game. It really should have been renamed "Dungeon Keeper Series" a while back.

My apologies, the DK forum is for both games: http://www.gog.com/en/forum/dungeon_keeper/#1317446404
