Strange accelerometer readings

[RocketRonz]

I have the frame rate set to 30fps using TargetElapsedTime = TimeSpan.FromTicks(333333) and it drops to the low 20s at times so there are performance issues with my game. I’ve posted another question about that here:

Texture optimization

Hi there. I’m porting my game from Android to iOS and am just looking for a bit of confirmation about the most performance optimal way to handle textures on iOS, before I go and change a large amount of code. The game works great on anything from a Galaxy S2 up on Android but the performance is very poor on an iPhone 4 with OS 6.1, with the frame rate consistently dropping from 30 to the low 20s. From what I’m reading on various forums, it’s better to use a few large sprite sheets as opposed …

Do you think that could be affecting the accelerometer readings?
