Hi there, fellow nerdz! I was going to turn this into a how-to and pro/con article on OpenGL on the Sony Vaio P (on Windows 7). But since I installed the XP IEGD driver for Intel GMA500 I have had nothing but trouble with it. For those of you that want to try it out for yourself, and/or want a bit more information on my massive fail, continue reading. To others: don't bother with this driver.
Update1 (2011-08-03): Seems like mmmsheen at notebookreview forums has discovered a way to unleash the performance of the GMA 500. Function keys still don't work, but wakeup from sleep does. Watch the video here.
