I don't know, maybe I'm one of the few here but I simply hate the default 3rd person camera in the game. Where the camera is adjusted right at the back of the character, it has always irked me being forced watch from that perspective.
I've already adjusted the 3rd person cam for combat mode, so it's all good and fixed but there's still the problem for the horse riding cam.
There's only one mod I could find that addressed the cam problem, but seems like it doesn't work anymore. All thanks to the recent official patch which introduced mounted combat...
Here's the video that shows exactly what I'm talking about: youtube.com/watch?v=x-x1DNZ4a38
So is there any way left to do this? The vanilla horse cam is just too terrible IMO, so much so i'd rather walk than ride most of the time. Not to mention, I'm playing a no fast-travel playthrough.
