    If it's not too much to ask Sebbbi, is it possible to post those cut async compute slides as well? I guess things should be more open to discuss now about DX12, I was speaking with @Max McMullen about Multi-Adaptor, and how iGPU mixed with dGPU, DX12 can have the dGPU to signal the iGPU to do work when it's done. But not mentioned in those slides is that during our chat he mentioned that the GPU if the developer chose to, could signal the CPU for the next step in the pipeline.

    I'm wondering if it's possible using async compute to have a core listening for those signals from the GPU to make an async call back to the gpu? This is a round about way of having a GPU issue its own draw calls?

    Perhaps DX12 can save AMD.

    I hope so. Something needs to.

    Yup. Before Nvidia's GameWorks program gets underway with DX12 based games and somehow magically staggers AMD performance.

    Maybe they're already looking into 12_1 features since you know, GCN _____. o_O

    So no 4k60 fps with a Dx12 Enabled™ Xbox One? :no:

    No but seriously, API hype marketing must be one of the dumbest things in the console industry the last few years, right after "The Power of the Cell™"

    Yup, seems a good summation. And on the positive side, confirms there will be at least incremental improvements with XBO and DX 12.

    I think MS highly customized the SoC: hardware memory coherency CPU-GPU, 32 MB ESRAM, move engines (compression), SHAPE and AXI bridge for audio, two graphics command processor, two compute command processors, and finally, they claimed to have "highly customise the command processor". If MS can add these features and they create DirectX 12, I am not surprised at all if it also support FL 12.1 and that AMD will bring FL 12.1 to their 2016 GPUs.

    There's clearly some dodgy accounting going on there. We know that the XBO GPU doesn't natively support either Conservative Rasterization or ROVs in hardware which are requirements for FL12_1. If Microsoft are trying to claim that it does then it's only via some convoluted semi-emulated method which certainly all GCN1.1 GPU's would also support.

    While all of this may be true and some of these types of updates may be incorporated into future GPUs, it's also fair to say that none of these changes are transformative. As demonstrated by the performance of the Xbox One.

    Anyone expecting increases in capability of the Xbox One beyond the usual incremental updates as the hardware and knowledge matures, will be sorely disappointed.

    And besides, as @pjbliverpool suggests; there are hardware features of FL12.1 that the Xbox One simply doesn't have.

    I'm pretty sure that XBO is only FL12. I've heard conflicting reports by MS employees on whether it is or isn't, but having said that, pretty sure it isn't.

    The slide is representational and not meant to be a data sheet. FAIRLY positive! Like 98% with a 2% margin of error that is it not FL12_1.

    Edit: lol Al. Allandor you can check my post history for the information you seek

    Clearly the Kinect is feature level 11_2, the console is 12_0, and the gamepad is 12_1. :nope:

    Gamepad is FL 13 since its firmware updateable.

    I thought FL_13 was Cell. :confused:
