since it looks like you run the game with default graphics settings i'm inclined to say it's a one-off visual bug, unless it happens more often/all the time, you should be fine.
as the title says, I will ask YOU questions
1. why is pyro amazing
2. why am i so amazing and based
3. why is skyrim and fallout NV the best bethesda games
4. more to come...
which era of transformers is better than idw transformers
why do you not like pyros
why do you bully @Elbow Removal Service, is it because he's a nerd?
