    What exactly does this choice do?

    The tooltip says it allows you to choose a faster but less compatible mode called "Never".

    Faster in what way? Compatible in what way? What will break, and on what devices? What buffer are we talking about blitting here in the first place?

    And does it work when running in XR such as for Daydream?

    Thanks!

    The buffer that it refers to is the screen frame buffer. When Always is selected then the final output is rendered to a frame buffer then blitted to the screen which is how it has always worked.

    If you choose Never then the output is rendered directly to the screen. Performance may be increased slightly because we are no longer copying from the frame buffer. However this is not compatible with linear colorspace, MSAA and non-native screen resolutions.

    There is a third option, Auto, which attempts to skip the blit unless one of those aforementioned features is enabled.

    I haven't tested with XR but it's possible that it may work. I just don't know conclusively.

    Thanks for the info, @Masterfalcon - I will give it a try but now that it's clear what it does it should be easier to test for its applicability in our games. Thanks again!
