The Razer Hydra is known to have a very bad accuracy past a quite short distance.
Only using the standard drivers. It can be quite accurate and precise if you eliminate the HID packets that report data from the wrong axes. And software can calibrate it for local magnetic distortions too. Jitter is caused by loss of precision, not loss of accuracy. Precision is how repeatable a measurement is. Accuracy is how close to correct the measured location is. My tests show that there are bad data packets distorting the filtered data, and custom software can compensate for this.
Although the STEM controllers will use the same protocol as the Hydras, the are using a whole new code base, so they should not have this firmware glitch I discovered. I also found a cool buffer overflow in the Hydra, almost identical to the heartbleed bug (letting you read a 4K chunk of RAM in the Hydra).
