I have just run the ioquake3 update (2010-03-10), and I notice a few issues.

1) For me the frame rate in the first level used to be 30-60fps (averaging approx 45fps). Now it has dropped to 22-35fps (averaging approx 25fps). It is still a decent rate, but I'd prefer it to be the higher value.
2) The movement control by accelerometer seems to be responding better.
3) The auto-aim seems to be off (by default). I haven't yet gone into the settings to try to adjust that. It makes it harder to fight the 'bots.
