Check out this video of Quake 3 running on Nexus One, rather flawlessly as the author says:
ANY LAG ON THIS VIDEO IS THE CAMERA AND VIDEO QUALITY. The game is perfectly smooth on medium/high-ish graphics.
Shit quality video of a Quake 3 port to Android on my Nexus one.
I’ve mapped the volume up to walk forward, and volume down to jump. The trackball is set to high sensitivity and works perfectly as a mouse. (Also, pressing the trackball is to shoot)
In 3 minutes i got 8 kills, 3 deaths. It’s definitely playable on a non-keyboard phone as opposed to a keyboard phone. ( eg Droid)
