Does setting ARKit to use 4K resolution affect the battery longevity? Does it increase the risk to get the device too hot, even if the fps is limited at 30 fps instead of 60 fps? Is there a way to get 60 fps at 4K resolution?
Yes, using 4k resolution may result in more power being consumed. It may also result in thermal mitigation engaging to keep the device from getting too hot, which may impact performance. At the moment, we are only supporting 4k @ 30hz.
