I was previously running XP 32 bit with a logitech webcam and could multitask without a problem during video chat in firefox/chrome. I've installed Windows 7 64bit and video chat is a major hog now. I can barely do anything during video chat. I can surf and listen to music but I was previously able to play WOW and use voice chat now I cant even do a data transfer from my external hd to my internal. Any thoughts or suggestions?
