[2023] Terrible graphics and story

Hello Ubisoft I bought Assasssins creed valhalla DLC. And After downloading it I asked Ubisoft for a refund. Ubisoft denied me one.

So now that I am stuck with this DLC. I hope someone from the community might help me with the graphics problem. Look at the screen shot. my settings are set everything to ultra. When i cave it looks even more terrible any advice how to fix it or is this as it is ?
