Hey! I just happened to switch over to Windows 8.1 Pro 64-bit. I previously had WinXP SP3. Now, i have an old laptop: Core2Duo T5200 1,6 GHz, Intel GMA 950 (256 MB) and 2 GB DDR2. The problem is after switching to Win8 YouTube videos lag in normal view (480p, 720p, doesn't matter), and they stop logging after going full-screen. But i rarely watch things in full-screen. With WinXP videos were smooth and no lagging occured. I have the latest Flash, latest updates, latest GPU drivers (considering Intel stopped offering ones back in 2009, so i used the ones Win Update offered). Is it because my rig is too old, and this Metro interface is eating up much of the GPU/CPU?
