OOOOOOOh... we've got a smart ass
Yes... I own this rig, yes, I know how to bind mouse buttons to keyboard, yes, I did build it myself, yes, I did design and manufacture the water blocks myself... yes, I could talk you through and walk all over you with binding keys, even down as far as BIOS level, but that still wouldn't satisfy your "I'm better than you" mentality, would it?!?!? So for now, let's just assume that I know what I'm talking about, and you don't, yeah???
I'm not talking about 3rd party software, I'm talking about Joe Bloggs binding his mouse to this POS game...
