I was previously running Vista 64 and never noticed my CPU usage getting so high on my G15 Keyboard. I just performed a clean install to Windows 7 64 bit ultimate. I got all the updated drivers for all hardware and updated my bios. I have a gigabyte Mobo, 4 gb ocz ram, gtx 285 SC, 750w corsair, e7400 2.8ghz wolfdale core 2 duo. I have watched my G15 during left for dead and cpu pegs out at 100% and Memory at about 60%. CODMW2 runs at 60%-70% CPU and 60%-70% mem. I never noticed this with vista. I have tried everything. I reinstalled window 7 a second time to check and make sure nothing went wrong with the install but that did not fix anything. I have watched process explorer and the task manager to see what was eating up my cpu processes during these periods of high usage and i only shows a few processes most of which is the game that I am plaiying. Sitting idle my cpu only shows anywhere from 1-3%. Is this all normal or should I keep looking for issues? I did have some problems with my usb ports cutting in and out during first install of windows 7. Could I have a Mobo issue? I would like any advice I can get.
Question: don't we WANT games to use more CPU usage?
As long as the system doesn't slow down, don't worry about it. Using Task Manager numbers is silly to begin with (Example: TM shows Address Space usage, and not actual memory usage. Big difference between them).
