I've update to the gma 500 driver version 220.127.116.116 (jun2010) in a vaio p 1.3Ghz (vgn p6xx series) and it works fine, except i've to downgrade VLC player to version 1.0.5 because I get noisy sound in avi movies.
With the 18.104.22.1686 driver in vaio p 1.3gz I am surprise that movies play smoother than in vaio p 1.6ghz with SSD (vpcp11 series - driver version 2024 which came in the notebook).
I tried install the 2026 driver on the vpcp but the computer lost the resolution of 1280x600 and it made the switch resolution button useless. I hope Sony be fast and delivery the new gma 500 driver for the vaio vpcp soon.
