Steve, not to be the bearer of bad news, but mouse lag is still very much a problem with wired mice. I've been using a wired Logitech mouse (and a wired keyboard) for some time now, and the lag in all of the CMx2 titles can be really bad at times. Seeing that I have a very capable system (SSD, GTX 680, quad-core CPU, 16 GB RAM), I can only point to CMx2's coding as being the issue here.
