    I've seen many mentions that this will be possible during 2018.2. Is it there yet and if, how does one force standalone build to use it?

    So far I haven't seen any difference on builds if one enables burst from editor so I'm guessing these settings don't carry to the build yet.

    Are you adding the [BrustCompile] attribute on given Job?

    Burst standalone support is not yet part of 18.2 beta, we are still aiming to get the necessary changes into 18.2 to enable burst for standalone players.

    If you are using a very recent version of burst (0.2.4-preview.12) with the latest 2018.2 and trying to build a standalone player, it should work but a bug sneaked into the editor menus in beta 8, so the experience today is not great, as the checkbox in the Jobs menu are wrong and/or inverted.

    We are writing the very last bits of the documentation to make an official release of the AOT mode. It should hopefully come in the coming days, by the end of this month.

    Oh wow, Burst indeed works now on standalone, thank you all :)
    Apparently just using the Jobs menu enables/disables burst from standalone as well. Would be nice to have some build setting for it I guess.

    I agree. That's something we will improve towards 2018.3

    How is SSE/AVX etc targets swapped atm? I know the setting in the Burst inspector, does it carry into builds too? I hope these things will be included in the player etc settings in the future if they are things user can set.

    Of course, I'd love to have that automatic fallback from AVX to SSE too which we discussed earlier (so "auto" would work out of the box for all target platforms) but it's not clear at all what Burst targets atm if you don't touch anythging. I'm assuming SSE2 ?

    In ideal case, you'd be allowed to pick the targets you want to support and Burst would compile variants for all of them with fallbacks to lesser tech.

    It should be SSE4 by default.
    If you look into the burst source in the BurstAotCompiler.cs, there is the method TryGetTargetPlatform that returns the default target CPU. We will add a proper setting but for this early AOT preview, this is still hardcoded.
