Using the Quest 2 with light in V40 are work fine. But when without light tracking (using the 3DOF mode) in V40, there is a issue. The whole VR world is keep following the HMD rotation. No like the previous (V39 and early) even I rotate my head, the VR world is not moving and keep in place. In short, this PTC update makes off light tracking (using the 3DOF mode) is completely unusable.
This video recording inside Quest 2 which show out how Quest 2 in 3 DOF Mode not working well.
00:00 - 00:29 : The Headset in 6 DOF mode. Function are completely fine.
00:30 - 00:54 : Cover the all tracking camera by cloth, force turned into 3 DOF mode. You can see the UI rotation are fine.
00:55 - 01:21 : This is issue of V40 PTC. After I clicked "Keep using when tracking function is off", the whole VR world is keep rotation with HMD. So the screen looks freeze, and makes me feel uncomfortable.
Hope Oculus or Meta can fix this system software bug as soon as possible.
