DeoVR works well on the Pico 4 via SideQuest. Now even Fisheye190 videos look good. The passthrough function looks great. The video "ASMR Closeup, Personal Attention from Xxlayna" looks incredibly good in Passthrough mode. Now I have an assistant in the home office. Maybe you should record everything in front of a green screen and only show the performers. I find the Pitch and Roll functions very practical in the DeoVR Player. However, the sound is not as good as in the Pico Player. Spatial audio can be selected for almost every video in the Pico Player. The spatial audio videos in the DeoVR Player do not work, although I have selected the function. In general, however, I find streaming better than downloads.
Spatial audio does work. But the effect is not as strong as when I download a video and play it with the Pico Player. Somehow I don't understand the issue. I thought Spatial Audio was a function of Qualcomm's Snapdragen XR2 chip?
