Graphics settings and using weapons

Tonight I noticed an issue when I changed my graphics settings from low to medium.

On low settings-I can draw my bow and strike with a sword.
On medium settings- I can’t draw my bow or sword. This issue is just fine on low settings.

It’s such a strange thing.

Other issues I’ve experienced are 2 side quests in Talmberg not beginning. There is a talk button but the NPC’s do nothing. I simply cannot speak to them (although chatting with other non quest NPC’s work just fine). I’ve tired waiting until day-then night to see if I could only begin the quests at certain times of day…and nothing.

Lastly, my horse gets stuck in the stables and floats in the air when I try to reverse him (then gets stuck in the ceiling of the stable). In Rattay (maybe).
