I tested polish gold version of Settlers IV (v 2.50.1516). The game works flawlessly out of the box. No slowdowns at 24 bit color. You don't need any NOCD workarounds.No DirectX needed. No Dll overrides.
Admin note: rating changed to conform to rating definitions.
In order to install the BlueByte Game Channel software (required for Internet play), place cabinet.dll in Wine's windows/system32 directory (normally ~/.wine/drive_c/windows/system32). Then start winecfg and add a dll override for cabinet.
If the game runs slowly, use a Wine version prior to 0.9.16. Then you'll have to follow the instructions below; newer Wine versions run this game out of the box
Instructions for old Wine versions
If Settlers IV crashes when starting a game, edit 'Config/GameSettings.cfg' in the directory where you installed the game, and set 'LandscapeHardware' to 0.
Add a DLL override (this can be done with winecfg) for 'Exe/S4_Main.exe', so that it uses 'native' 'msvcrt' (msvcrt is installed with the game)
It is recommended to upgrade to the latest version, as you may have copy-protection problems otherwise.

Try switching to 16 bit colour depth. Use your distribution's program for changing display/graphics settings, or change DefaultDepth in /etc/X11/xorg.conf
