Phoronix: Rewritten NIR Code For Old Radeon "R600" Linux Driver Improves Performance In 2022

The open-source Mesa "R600" Gallium3D driver for supporting AMD graphics processors prior to the Radeon HD 7000 series, a rewritten NIR back-end has been published that enables better performance and proper FP64 usage...

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?

Time to dust off my Sandy Bridge notebook with a 6770M - unfortunately all the good stuff that made Linux gaming great (Vulkan, Proton, DXVK etc.) needs at least GCN 1.0.

Isn't Proton just an improved WINE? Does it really need GCN?

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).

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.

I'm aware of Vulkan. I asked specifically about Proton.

I may have to give this a spin on our HTPC, which is still running a Llano 3-core CPU.

I had honestly figure on that machine riding off into the sunset with it's current driver stack.

With HD 5000 and HD 6000 being DX11 (11_0) compliant GPUs, that also means they support OpenGL 4.6 on Linux, right?
