I found that performance has dropped a bit since switching from Vista (32 bit) to 7 (32 bit). Vista has always run smoothly for me but since trying out Windows 7 I've noticed lag in several areas such as: - Choppy screensaver - Highlight box (when holding button down on desktop and dragging over icons) is jumping - Framerate when playing videos in realplayer doesn't seem to be up to par - Typing lag - A bit of jumpiness when moving windows around, or minimizing them - World of Warcraft is choppy when in windowed mode (but runs fine in full screen mode) Hopefully that all makes sense. The choppiness isn't overly horrible but definitely enough to be easily noticable. Here are my relevant specs: -Core 2 Quad 2.4 -4 GB RAM -8MB Cache -500 GB HD (75% free) -nVidia 8600 GTS I'm pretty sure this issue has 'video driver issue' written all over it. I updated to the drivers that nVidia released specifically for windows 7 under windows update (their "prerelease WDDM 1.1") but it didn't seem to help. Any thoughts or suggestions or similiar experiences to share would be greatly appreciated!
