I have recently bought a new machine, and I was lazy enough to do a direct hardrive swap (without a reformat) from my old machine to the new one. Although I had a heck of a time replacing drivers and getting everything to run decently, it did work fine for a time. But just recently, I decided it was probably good to start from scratch. So, I reformatted my computer.
The problem I'm encountering now was discovered while testing World of Warcraft with the new machine, after I had formatted. This worked perfectly before the format, but now, I have this problem:
When in Normal full-screen mode, everything is fine. When I alt-tab to another program, WoW's cpu usage is regulated as a background app, and brought down to a low amount. BUT, when I run WoW in "Windowed Maximized" mode, my CPU seems to be treating it as just anohter windowed application. When I bring another application to focus, WoW continues to run at the same CPU usage, and my system starts to lag until WoW is the focus again. Is this a problem specifically with World of Warcraft, or is this some setting with my CPU or graphics card?
I'm running a Core 2 Duo 2.13ghz processor.
