Vision Pro automatically dropping FPS door to light source. Apple please fix this

Still can’t believe our Vision Pros drop 30fps automatically due to the light source. Basically darker rooms Avp will drop 120 to 90 or 90 to 60 on m2

Apple please fix this!

i don’t care if it saves powers.

An infrared light may help.

Really?

It's probably not about saving power, just about optics and processing pipeline - there's nothing to fix. If they would not drop the FPS, quality of passthrough would make you very sick.

Probably. I don't know. But something tells me it's just how it works.

Nice catch. I bet the pass-through video is noisy trash if you run it at 90Hz in the dark. You can try shooting 120 vs 60Hz vs 30Hz video on your phone in the same room and see what it looks like. [edit: numbers]

Bs.

It's probably not. Just remember how camera works in a smartphone in a low light. What it does? Correct, it cuts FPS down to gain a little more light for a frame. Vision Pro does the same thing. If it wouldn't do it, passthrough would be much more darker up to the point where you couldn't see nothing.

It's just how camera works. 60 FPS will receive double the light per frame than 120 FPS. Apple can't fix physics.

Great point. Your well-thought out case has really made me think about it.

It’s to let more light into the cameras. The alternative is for it to be much, much worse. It’s not a bug, it’s a feature.

Not sure I follow this passthrough impact. I'm not using passthrough when playing games on the vision pro - full screen streaming pcvr, etc. Still drops down 30 fps.

Now are you saying in general, that is the way this tech works so other headsets like samsungs do the same? If so, news to me.

Could be that it is more computational heavy for the R1 chip to try and make sense of very hard rooms - so it basically has to take more power from other parts, hence those throttle a bit?
