Everything else is normal. It's just a minor nuisance but if someone knows how to fix it, that would be nice.
Some infos: I'm using the pre-configured version of the game (with Dosbox) that was linked a few times on these forums. Running on WinXP.
Btw, Daggerfall is a pretty amazing game. A paradise for a dungeon crawler like me. ^^
Edit: Finally found how to fix it. It's kinda funny actually. The NPCs were super slow because my game was running too fast. Once I lowered the cycles in Dosbox, they were able to walk normally again. Also, my horse doesn't sound like he got 24 legs anymore. Yay! It was giving me a headache each time I used my horse.
