Outstanding work.
The G15 controls and stuff can go goofy, often from u plugging it into another usb and windows gets confused. U plug it back and u`r in screwsville. Reinstall of the logitech thing sorts it out.
Have u been to the G15 forum thingy (which I can`t remember site of atm) - has some really sad looking crap on it tbh. But there`s a devs kit download too, which is semi interesting.
And if u got AMD, the info tool is pretty much a waste of time. Tells u what cpu u have plugged in... with the default clock speeds etc. Ignores any oc.
Oh and my lcd thing is burnt, it`s worth cycling displays.
