Here is a list of configurable options for the config.ini located at %APPDATA%\GOG\DungeonKeeper2\config.ini

i.e. try adding

Antialias=12
HighRes=1

to your config.ini to enable high res in the GOG edtion

That's a little more than just the ini settings. That's a dump of pretty much every string in the dll. :p

If you're particularly interested in what's in the ini, here's a complete annotated one for you, along with the defaults:

[Video]
Antialias=11 ;Controls antialiasing and also the fps fix for the main menu. 0, 1, 2, and 12 are also valid settings.
ExtraAntialias=0 ;Doesn't do anything on any graphics card less than 10 years old, afaik
HighRes=0 ;Allows you to pick higher resolutions, at the expense of broken menu text
Anisotropy=0 ;Adds anisotropic filtering on textures
Vwait=1 ;Controls vsync behaviour
ScaleMode=1 ;Controls screen scaling behaviour, particully if your screen isn't 4:3
DisableFourCC=0 ;Disables some specialised texture formats, which may solve crashes on some graphics cards at the expense of corrupting movies.
Bumpmap=0 ;Enables bumpmapping effects on water/lava. I have no idea if it looks like it's supposed to though. I prefer the original water.
RealFullscreen=1 ;Set to 0 to run in a fullscreen window. Can help with alt-tab crashes, but can have some side effects.

[Misc]
CpuIdle=0 ;Turn up if you don't want it hogging 100% cpu time
;Not really any advantage to changing any of these
SingleCore=1
DisableDEP=1
RestoreMode=0
NotOnTop=0

I don't even have config.ini in my directory. How could that happen?

Yes... :) i did dump it though. I wanted to encourage people to get out and play with things. I miss my bump mapping! But thanks for explaining the commands too, new / accurate info is hard to find.

Hi timeslip, since I am so annoyed with the fireball bug I tried to install the patch to version 1.8. However, its normal DKII.exe refused to start (as does the one in the GOG installation), while your DKII-DX.exe did manage to start the game. Hoever, with the 1.8 patch the sound became extremely choppy, to the point that it was almost not understandable.

Is there a way to get the improvements of the 1.8 patch to work with your hardware patch? I keep hearing that in later levels, with the 1.7 version certain creatures won't appear.

here seems to be a version 1.8 DKII with the timeslip dll...

You should maybe save your original executables (e.g. rename them DKII-dx.exe -> DKII-dx.org and DKII.exe -> DKII.org) and copy the versions from the archive in your DKII directory.

PS: rename the files in the archive to the correct name, some are misnamed as "DKII_dx.exe" instead of "DKII-dx.exe"
