High CPU usage with Windows7

I'm trying to lower my CPU usage for CoH. With only CoH open its around 96% and the jittery movement, even though it is minimal, gives me a headache after a few minutes. I recently installed windows 7 which is when the issues started, when I was running XP I didn't have any issues. I've even lowered some of my ingame settings but don't want to lower things too much and lose all the pretty, though I'm not opposed to lowering a few things if it will make the game playable.
I thought maybe it would help to install CoH on the hard drive that isn't running the OS but didn't want to go through reinstalling if it won't make a difference. Any help would be appreciated.

So after a clean install and updated drivers it runs slower is what your saying? Have you checked for malware? If this system has not done much since install and its slower I am not sure what else to check for.

Thank You Devs for Merits!!!!

I run Vista and I noticed a spike in CPU usage when i21 went live.

It's possible they made a code change that as a memory leak or some new bit of code is not meshing well with something else.

IIRC prior to i21 I would run at ~75% CPU usage. Now it's closer to ~95%.

(I use a dual monitor setup and have a CPU widget on the non-game screen).

*shrug*
