A dxdiag log and the kcd.log could be helpful. Can you upload them here?
I actually run a program that updates all drivers on my PC
Sure, where would the KCD log be located?
In the game folder.
Please try a clean gpu installation. Dxgi_error_device_removed Crash
Do you have the gog version? There should be an update for you.
Updated and also performed a clean GPU installation, but sadly didn’t work
After gpu installation you turned your pc for a least 5 min off??
When it was done I shut down while I ate lunch and smoked a cigarette, didn’t time it but should have been at least 5 minutes.
You can try down clock your gpu a bit to see if there is any difference.
If you write to support@kingdomcomerpg.com you can refere this forum post here.
Okay I’ve got the game actually working now. Kind of.
Basically the intro is still black, but if I wait around three minutes the game starts. Without sound.
I can make a new game, play like normal no problems… except no sound.
Sorry I vanished for a bit, the forum wouldn’t let me post any more.
Nice. Now try to remove your sound card on the device manager and let windows reinstall it.
Btw: Post Limit removed. 
How would I go about that? I have device manager open, but not sure which of the things under “Sound, Video and Game Controllers” to uninstall.
Can you give us a screenshot?
Remove your headset and Realtek hd audio.
And deactivate dfx audio enhancer
Okay, done, and restarted. They reinstalled themselves so that’s all normal again. Started the game and the load screens are working again, though not the intro screen, but sadly still no audio 
Did you try deactivating the dxf enhancer?
Yes it’s disabled as well
