    sinepgib Vulkan needs mandatory GCN, ergo no Vulkan on TeraScale.

    However, Gallium Nine works great on those old old GPUs, so theoretically it would make sense to make d3d10umd also compatible to the Mesa hardware drivers. This would give us then native D3D10 and maybe also D3D11 on Linux.

    Yes Proton is basically a custom Wine with added ease of use.

    Technically you can use a pre-GCN gpu however due to lack of Vulkan support you'll be limited to OpenGL which in most cases works best for old DX9 games (and with less performance than DXVK).

    Dust of all your r600 card please. From the comments it looks like the new backend should work on more cards but hadn't been tested due to lack of hardware, the dev put instructions on how to enable it for more cards in the MR
    Is there a way to suport the Dev by sending him a Card or giving him remote access to a system?
