Gonna agree it's a bit OP - one vulture is fine, but so far I'm only encountering them in groups of 2-6, and a LOT of wolves. Don't mind it being hard, and don't mind having to run; but for early game silent fast killers are proving a bit much for me, and I'm a fairly experienced player. Not helped by getting massive lag and frame rate drops when hit / bleeding.
Hoping the next drop optimises the frame rates a little, and maybe tones down the number of Vultures / wolves in early game.
