The only issue(s) I've been having, which I was also having in SC2, were that the response rate for my mouse seems to be a little jittery:
For example, I can move the mouse flawlessly from various parts on the screen, minimal, etc. but when I go to repeatedly drag a box over my SCVs, marines, etc. the response rate immediately crashes and it almost has to speed-back up again to get to where it was just a minute ago. I'm currently using the SteelSeries Exact Mouse software AND Razer Synapse with my Deathadder 3.5G.
Any assistance (outside of telling me to buy a PC) would be most appreciated.
