I bought a G2 but had to go back to my Index. For me, the G2 kept "losing the room" and the game would go to a funny angle. I just never could get the G2 cameras to work right on my setup, I mean the cameras for motion tracking. It would just lose me all the time.
Could be to do with how your room is lit? I think that too much or too little light or perhaps bright light shining directly onto the HMD can cause issues. I've been fortunate and not had that issue, generally playing in a well and evenly lit room.
I did have one instance where the view was just a little off when playing MSFS and was able to fix that by going to mixed reality settings in Windows and under Environment clear environment data. Might be worth a try...
