Can you test if the game can handle horse tilts at high speeds? Does the rock in the main quest route work? Can you wrong warp with it if you get out of bounds with the horse tilt? Is it controllable?
I have too many questions D:
I would love to help but I don't have a console, if you're on the discord I could speak with you about it too :p
There's currently no console version of other runs because no one has ran those categories on console. If you want to run these and submit these times, we might be able to make categories for console runs, but the lack of runs is primarily the problem.
Quick note, you can do the power attacks without using stamina.
I'm pretty sure that horse tilts do not work on console, and there are multiple other tricks that don't work as well. The current console run record does contain all the doable tricks on console I believe.
To trigger marriage, you start at the throat of the world with Paarthunax. You first make a quicksave. Fast travel anywhere, and then quickload. Then fast travel to go to marriage. Do not make any quicksaves or quickloads until the cutscene ends.
I have had this problem on PC before, and it was due to my laptop being on battery power instead of being plugged in and charging. I believe that this might be a similar problem and has to deal with how fast the game can run, which is why higher end PCs end up being a lot easier to run on as most things are able to load quicker. So if it is a problem like that, I don't think you can do the horse tilt on console.
