I'm definitely not new to playing shooters with a controller, but I find the analog stick controls a little floaty/weird. Maybe the acceleration curve is just too steep for me (ie: the reticle either moves too slow or too fast), or it could just be an issue of control latency. I'm not really sure. Has anybody else had similar issues?
Also, I noticed that Dust 514 supports KB/M controls. How do they compare? I don't really have any good way to play with KB/M in front of my TV, but if it's worthwhile, I could hook up my PS3 to my PC monitor to at least try it out.
