Loadwarp should work, someone mentioned a while ago in the discord that they got it. Horse tilting I would expect to work too, the physics and mechanics shouldn't be much different. Enabling control with marriage could be possible. All we're doing is QSing on the time wound, fast travelling and loading back on to it. I haven't tested it at all myself but I would guess the loading back on to it is the main factor, QSing just being faster.

I really love the idea but I'm not sure how realistic it is to route. You'd need to approach it in a very casual manner, as in just having a very rough idea of route and strats, otherwise it'll take forever. Each of the guilds took me 2 months to route, and just rerouting main quest took 4. This means it might not really feel like a speedrun. That said if you don't worry too much about the order of things and efficiency and just focus on finding decent strats for each individual part it could be doable. Being segmented helps a lot too, it wouldn't take too long to pull off a segment of tilting around skyrim discovering every location. After that you just need to quest and collect like a madman with fast travel and some dungeon strats.

In my opinion a good compromise is 'All Main/Major Quests' as it's much easier to define and properly route as well as still being very long. I guess it would include Main Quest, All Guilds, All Daedric Quests, Civil War and maybe some others that I can't remember.

I quicksaved midair, tilted and quickloaded, then went backwards and forwards (going forward is locked until you go backwards first) to set my momentum as going forwards then reloaded the save and landed in riften lake by going first person view to cancel my speed.

My Skyrim has been unplayable for a while now, it just completely glitches out straight from the off. Example (). I've tried uninstalling all mods and reinstalling the game but to no effect.

Another thing is I keep getting my old saves back when reinstalling, they just keep reappearing. Is there any way to get rid of them? I've tried deleting them from C:\Users\Documents\my games\Skyrim but they just come back. I want the game back to be how it would be when first played.
