Being one of the guys that weren't particularly happy with the movement speed of the characters ingame, i figured i'd give it a shot and see if i could mod it somewhat.

After messing around i eventually was successful. Took me a while to figure out that i needed to change the movement speed not for the player character objects but rather their root template.

So i increased their speed by about 30%. It seemed like a good compromise between playability and looks.

Keep in mind that this applies only to the 2 player characters. I'm not sure if it works for companions since i didn't get a chance to test it, but it can be improved pretty easily.

Anyway here's the link:

Just copy the content of the zip to your divinity game dir and make sure you activate the mod in the main menu. Also you'll probably have to start a new game.
