Is it possible to measure the current free video ram with a command or something? or how much video ram at least to have, to play a 1080p video?
I got a 8600GT with 512mb, sometimes after X up for more than 7 days, it will not allow me to playback 1080p videos, but at least restart X solve the problem.
