I used all the fixes in the first post, and the video is much smoother. However, the fan on my laptop is spinning much faster all the time. Instead of being inaudible at idle, it's spinning at about half its max speed. Opening or doing anything sends it into overdrive.
Anyone else experiencing this? The gain in video performance isn't worth the fan noise for me.
I'm using an HP NX 6110, Intel 915GM.
