    Which version are you using? Last time I checked it had a bunch of controls for SSR. (although even with all the settings I couldn't really get satisfying results from it, but you should be able to somewhat improve the first image).

    Maybe they added the extra settings in 2019.3 and 7.1.2, since that is what I've been using.

    You probably have sky reflection enabled. It simply doesn't work properly (it's always crazy artifacts around the object edges), if you disable it, it'll give quite nice results.

    For me PPv2 SSR was totally opposite to your experience, I never got anything usable out of it.

    How do you disable it?

    Is there a way to improve SSR level of quality and keep preformance ?

    @rakij23922 have you added the Screen Space Reflection override in your volume profile?

    @AcidArrow both 2019.2 and 2019.3 have the same settings in the override, although the order seems to be quite different in Inspector UI.

    2019.2:

    2019.3:

    To get some of that "disgusting" look away, just dial in more Max Number of Ray Steps. It will improve the quality.
    Looks to my eye more like a pilot error than fault in the software. It's clear that the settings have changed and the look is not the same but it's still quite usable to my eye.

    32 steps:

    64 steps:

    konsic and AcidArrow like this.

    ofc hdrp ssr (gosh why they make so complicated names) more accurate, but the old one blurry ssr was better for my design choice

    Do profile your project if you go to 64 rays tho, this will have notable effect in the performance, especially on weaker hardware.

    @rizu for sure it will have effect (I'd imagine, as it's potentially double amount of steps), the point was just to underline that the image artifacts are something that can be removed.

    You have to wait one more year for more dissapointments :) I dought that they will fix it without making you switch to unity 2021.3 or something
