For you guys with good systems having performance issues, I have notice that lowering the shadow quality from Ultra to High improves performance (fps) almost  twice.  

Talking about shadows I don't know what in hell tripwire did with their shadows because it seems to be pretty fuck up:  CHECK THIS OUT Aparently they have a total noob working on character render and lighthing. I tried myself and Indeed if you go lower than medium in Shadow Setting all soldiers start glowing like radioactive zoombies.
 
I'm loving this game now (18 hours in the beta so far), I really hope they fix this issues, I would hate to see it flop because of a broken launch. 

omg this game and people who are gonna play in the GB runs for this game dont fucking do this ill get really mad.

Don't worry they stated that they fixed it for the next beta release.

That's pretty funny actually. It's like Eagle vision or something.
