Just read this today, was confused by the memory of it being released already, saw the date of your post. "Ah (,so smart!)".
I refuse to try it until my gaming rig roars to life again (I'm missing the HDMI-VGA adapter to have a screen, using only HDMI made a horrible mess out of resolution and fine tuning)... I remember when I tried it out on my uni ultrabook... the lag... horrible.
