With these two devices disabled all is fine in FEAR for me running the G15 and MX518.
Same fix worked for me, in addition to unplugging my G9 all together. No problems when plugging in the basic MS optical mouse I use with my notebook. As to the link posted to CNET, I don't think this is an issue with PC gaming as a whole because it seems that F.E.A.R. is the only title where this issue rears its head.
