Firstly, yes: I’m on a laptop. No: it’s not a complete hunk of junk. It does the job. 
This may or may not have been discussed here before, but I feel that the developers should be focusing on optimization as the game progresses through the Beta. When I play games like Blacklight Retribution, Insurgency, and Killing Floor 2 at higher framerates than Dirty Bomb, it just doesn’t feel right. My frames average from 30-50, but seem to dip down into the 20s sometimes. What is it about this game that makes it so intensive on my computer? I have, of course, lowered all of the settings I can. Is there anything else I can do to help increase my framerate?
