The last video from CyanogenMod showed that the sound was too fast and a couple of games there were not working at the correct speed. Though people in the YouTube comment section are saying that the Dungeon Defenders was not shown properly with some of the screen being cut off.
Greentheonly displayed the hardware-accelerated video playback. Not to mention that high quality YouTube videos are working. This was not previously the case. Still we are waiting word from the CyanogenMod team on when the downloadable ROM will be working. Currently that have indicated that the ROM inself is in alpha stage and is not stable enough for regular usage.Hopefully it will be available to us soon.
