I did a diagnostics session with Apple Support and they found no issues with the Gyroscopes/Accelerometers.

Here is my guess though.

The gyroscopes have to be sending coordinate data to the app.

As the effect seems cumulative, i.e. the behavior gets worst over a race, improves with a device restart, but then talis off againd, it is likly that:

Either iOS changed how that data is presented, maybe they changed rounding or bits of data that they send, or the older gyroscope hardware isn't communicating properly with iOS, in other words they are telling it one thing, but it is interpreting it another way, such as with a change of bus size between the chips in newer models.

Assuming it isn't an iOS issue in the sense that the data is inaccurate, then it could be how RR3 handles the data (assuming it is in a slightly different format). It is also possible they recoded for the behavior, but because older devices cannot send the new format, then we get weird behavior.
