    Can be found in URP.
    "All Faces At Once": spreads update over 9 frames
    "Individual Faces": updates over fourteen frames

    Without them realtime reflection probes in HDRP are unusable for any project that cares about FPS.
    Although we have onDemand, the update cost is massive as it does all the work in a single frame.

    Don't know why such performance heavy feature does not have any important optimizations and i also cannot lower the resolution below 128 (which is possible in URP), frame settings does not improve the performance much and i feel that reflection update settings must be included out of the box instead of writing a script and also time slicing's update frame period must also be available as more optimization options

    Yeah frame-settings for the reflection probe actually do next to nothing from my testing. I removed almost everything and the cost is around the same. It costs far too much, even a single Realtime probe will cripple your performance.

    exactly! I am unable to figure out the reason behind implementing reflection probes in a way that makes them unusable in real time? Maybe just stick with the baked version since no one is able to utilize them in real-time?

    I use mine ondemand and with a manager that updates them one by one over several frames. It works for me since my scenarios are just random starting time of day/weather and toggling some lights (like switches or shutting down power generators), but yeah, for true realtime they would be unusable.

    Simple. "We got this feature" kind of talk. Unity can show you that they got this feature on a conferences and youtube videos.

    About month ago I have sent 2 bug reports regarding real time Planar Reflection Probe.
    I got no answers since.

    But is it due to the steely policing gaze of PutridEx or a metacosmic coincidence? We will perhaps never know.

    OMG what a godsend! No longer having to queue my reflection proves by script over frames
