This review is from: Logitech QuickCam Deluxe for Notebooks (Silver)Just like the 5000 series cameras before these (the "9000" series), Logitech has built a camera that puts out superb video (this one's video is better than the 5000 series, and those were better than the 4000 series).However, the software, lack of control, and enormous pile of bloatware that gets installed with the camera, coupled with its enormous system resource demands, make this another clunker.Environment:P4 2.4 GHz processorWindows XP Pro SP 2DirectX 9cUSB 2.0First, the good:Color and picture quality are outstanding (although focus is not good - more on this below). The new support for large quasi-hi-def picture sizes produces amazing images.Now, the bad:Machine resources:You better have a FAST machine. And I mean FAST, like a Core 2 Duo, or forget it. A simple 320x240 capture/preview (not even writing the video to disk) sucks down 10% more CPU on a P4 2.4 GHz machine with Windows XP Pro, than the old 4000 series cameras did.Holy cow --- a 2-way 30 fps 352x288 video conference with the older 4000 series camera would use 55% CPU on my test machine. With this camera, it's about 80% and that's with auto focus, auto-white-balance, auto everything turned OFF and NOT using the audio from the camera.This is just like the 5000. And just like the 5000 series, once THIS camera's driver has been installed, even the older 4000 Logitech camera now uses CPU like a pig (this thing overwrites DLLs that the older cameras also use).I've been down this road before. The only way to make the older camera work efficiently again will be to completely uninstall this thing, and reinstall the old driver.Support for other applications:I only test these cameras using Amcap and Vidcap32 (the ubiquitous, standard, simple, generic Windows capture apps) and our own custom-written videoconferencing code that I wrote myself. So I have nothing to say about Skype, IM, etc.Just like the 5000 series before this one, this camera DOES support the proper DirectX interfaces. So if Skype or some other app is freaking out on you, it is not this camera's fault. It is Skype, or whatever app you are running. My code works just fine with it.But... just like the 5000 series, if you install the "driver only" (to spare yourself the bloatware), half the camera's functions will be broken.When I installed it driver-only, it would only do about 10 fps, in any kind of light, with any picture size, no matter how I set it.After I installed their obnoxious applications, it snapped into shape and would obey settings to do 30 fps.Bloatware:It installs services and several auto-startup pieces of junk that you have to hunt down in the "Run" folder in the registry and delete. Otherwise, every time you log in, you will have these things running, and the tray icon app, and two other apps, will always be running. No matter what you do, these w...
