Baked reflection probes in HDRP destroy FPS

    I have about 10 baked reflection probes in the scene. Disabling them, increase the FPS from 15-20 to 30-35. Why does this happen at all?

    Mine wont even bake. Baking them does literally nothing.

    Okay, this is really weird. I thought that the realtime shadow or volumetric, or some other hdrp stuff kill my performance, but it's not! (well not completely) This is makes by reflection AND light probes. After I remove it from the scene, performance boost in two or more times.

    And no, I don't have too many light probes in the scene. I'm even try it on empty scene where I put 7 realtime light with shadows, and about 8 light probes. With no baked probes performance is nice, but after baking it's slow down badly. I don't think this is correct behavior.

    Sadly I can't send bug report, I don't even internet on machine where unity install, and my project weight is over 20 gig

    Ok, I got that. It's not about light probes, but about "shadowmask", when I switch on "indirect" mode, problem with light probes disappear. But reflection probes problem still there.

    We have a similar issue. We're using realtime reflection probes since we need a dynamic day/night system with user controlled lights. There are 5 reflection probes in the scene and when turned on they totally destroy our framrate (even when NOT in play mode). Anyone have any leads?

    DoubleLens is your realtime probes render every frame? If yes, then of course they destroy fps. But I'm talk about baked probes, and they still lowering framerate.

    I can't change the update frequency (it's stuck on every frame and greyed out)

    DoubleLens ah, yes, they did this again. Maybe this is somehow connect to my problem too.

    Hi,

    which version of Unity and which version of HDRP are you using?
    2019.1 and 5.2.3 is unusable for reflection probe if it is what you try to use

    SebLagarde I'm using 2019.1b now. What are you doing, guys, with reflection probes out there?

    Hi, Thanks for your post, there is actually a bug in the cache of the reflection probes.

    They were convolved every frame instead of only once, hence the performance hit.
    A fix is currently on its way.

    Any updates on the "locked" baking of Reflection Probes? Is it possible in 2019.2?
