For several months now, I've noticed large CPU usage on what should be simple tasks. For example, all I have being displayed right now is Task Manager and a Chrome window, and Chrome is taking half of my CPU (3GHz quad core) just because there's a Flash ad playing above this text box. It's even adding a noticeable processing time for typing this message. Scrolling until the ad is no longer visible reduces the load to 25%, but typing in this text box adds another 25% or so, in a separate process.
If I use Select All in a Notepad file with enough text to require some scrolling, I can actually see the cursor going through the whole file (over a fraction of a second, but still). Toggling word wrap and resizing the window have noticeable processing time, and resizing also causes the text to flicker.
Even the simplest tasks, like moving the cursor around any text field, require inordinate amounts of CPU resources.
I made a short video (18 seconds, <500K) illustrating the problem. In it, I start to rename a folder in Windows Explorer and drag the mouse around. You can see flickering and high CPU usage. Link: http://www.tigerhawkt3.com/videos/problem.avi
I don't know if it's a hardware problem, software problem, power problem, or what, but my best guess is that something is wrong with the hardware acceleration.
