First thing I did when I got my S10 was to look through the BIOS setttings for a way to increase video RAM. No Luck! Probably the most minimal BIOS settings I have ever seen on a computer! Pray for BIOS update!!!
it turns out that the amount of vram on your gma950 is depenant of the amount of total ram, and the current application. IE if you have 1gb mem your max is 128mb and a 2gb system will have 224mb. but if you just surfing your vram will be low 8mb on mine as i type this!
