How do I downgrade or fix not being able to watch videos on one monitor and play video games on the other? I have 2 monitors, and I usually play games like Civilization V or Tropico 4 on one and watch Netflix on the other. I've recently "upgraded" to Windows 8 from 7 and I get lag, a lot of it, when trying to watch a video and play a game, it used to work smoothly before the upgrade.
