Delixe: If you are using ATI then you have to forget Hardware rendering. You can however tweak the game using Regedit to change the resolution (I'm using 1920x1080), command line flags like -32biteverything and finally the modded exe that allows you to zoom out further.
32 bit everything?
I tried the unlimited Zoom and setting the resolution to 1920x1080. The game looks quite nice like this. I do not remember how it looks with 3D hardware acceleration, I am not sure I even tried that when I played it the first time. Would be nice if somehow it would be possible to use Direct3D, but its actually better than I remember it with these settings.
The menu is still a bit laggy, but that is part of the game. Seems to me some people expect GoG to remake the classic games, so that they would run better than they used to. Sometimes they do run better than they used to, but that is a bonus as I see it.
I have played through the first 3 missions now. I have only got the game crashing when I tried running the game in 1024x768 and play a challenge. I have been playing the new Dungeons game quite a bit since that was released, and the game is entertaining, but it really doesn't beat Dungeon Keeper 2. Dungeons for some reason became a strange mix of Theme Park and a tower defense game, while you have your Dungeon Lord and he is cool to have, but minions should be more than just almost static defenses. Also it just doesnt feel as nice that the minions are all upgraded in level at the dungeon heart instead of from combat experience and training.
Still it has a nice hero system where I got to put heroes in jail and torture them. But having to entertain them and adding decorations to your dungeon, just feels like a chore.
