I've had mixed results with tilt /accelerometer games on the xoom so far. Jet Car Stunts and Air Attack HD lite seem to work fine. Homerun Battle 3D works but you can tell its not optimized for the Xoom. Doodle Jump, Sniper v. Sniper, and Heavy Gunner 3D don't work correctly at all. Ex Zeus was just updated to support Tegra but the tilt is still messed up, even when you calibrate it in the game. Anybody else having the same problems?
