I have dual AMD Radeon HD 5850s. A little old, but should be able to handle these graphics levels.
Freaking wolves man... I headshot on the first hit (sticking out of his ear), then 4 more into his forehead. On the fifth, he turned around and ran off, regaining all his health. You really need to try killing them yourself before releasing this.
EDIT: Finally killed wolves. Cheese... "Here's a sword! Go kill some wolves with it" <Die repeatedly> Kill wolves with arrows... "Thanks for the sword, it's great!".
Also, you should totally turn off wolf respawn and running away. If there are 4 wolves to kill, I want to kill those 4 wolves, and see their dead bodies where I killed them, and not have them disappear in 30 seconds and pop up alive in 40. I ended up killing the same stupid wolf 4 times because I didn't want to risk kiting the next one into the area of the first one, or another one I didn't notice before.
