    Yeah, I know... I was asking about what was known about versions 2.3 and 2.4, aside from the fact that they existed...

    I found these changes after scrummaging through some headers and I've probably missed a few things...

    2.3:
    additional d3d memory allocation types
    SDR White Level control
    adapter paravirtualization
    Arbitrary Code Guard
    configurable DisplayRender timings
    detachable adapter support
    display configuration support
    source owner support
    display redirection
    ColorSpaceTransform support
    protected device session
    process device removal (checks if the process using the adapter can recover from graphics device removal)

    2.4
    hardware queues
    IOMMU support
    blocklist support
    surface swapchains
    device guid lookup support
    version query (bios/architecture information)
    perfdata query (clock frequencies (current/max/OC), voltage (current/max/OC), memory frequency, memory bandwidth, PCIE bandwidth, fan RPM, power usage, temperature (max/warning), power override status)

    Thanks! At least now I know I am not missing out on any kind of worthy optimizations. It looks like it implemented as OS defaults what video drivers and tools have been offering for a long time now.
