George,
I'd not worry about any resource utilization by Adobe Gamma since it is not a "TSR" (terminate and stay resident) application. In short, leaving it in place will neither help or hinder you since you're using an LCD panel, and it doesn't really "dirty up" your PC for what I understand.
Actually, it is more correct to just call that startup shortcut the Adobe Gamma "Loader". Quoting Ian Lyons ( <
http://www.adobeforums.com/cgi-bin/webx?224@@[email protected] 3f/10> ), what it does is "load the gamma curves from your color profile into the video card's gamma look-up table" when you first boot into Windows. Now, knowing that one can set up a color profile in their display properties, I've never been too sure as to what Adobe Gamma does that would be different, but I leave it alone since it is apparently needed to ensure good color management.
While I don't believe any harm comes to leaving the Adobe Gamma Loader in place even if using an LCD monitor, it will become a player if you ever attach a CRT and create a profile for it using the Adobe Gamma control panel applet. If you don't expect to be using a CRT at all, I'd move the Adobe Gamma Loader shortcut out to some other location, such as My Documents. That way, you can easily restore it to the original location if ever needed.
As I think of it, since the Adobe Gamma Loader is placed into the Startup folder, it is executed only after most of your Windows initialization has completed. With that in mind, I see no reason that the shortcut couldn't simply be moved outside of your Startup folder so as to be available to run on an as-needed basis. Then, if you ever connect to a CRT you could just perform your calibration and run the loader from its alternate location. Hopefully someone here will correct me if I'm wrong in that statement.
Regards,
Daryl
