Isn't Proton just an improved WINE? Does it really need GCN?
A 6990 with a rewritten Mesa driver, rewritten OpenCL driver, and a fresh Vulkan driver would be beautiful.

Why is people still answering me about Vulkan drivers? My question was about Proton requiring GCN, I think that's pretty clear. Proton can work without Vulkan (as the first person to answer confirmed), just obviously Vulkan games won't run. So Proton can also run without GCN, as I expected.

Hmmm OK. I thought it was more like PlayOnLinux that provides viable configs for the different games, but for those shipped by Steam.

IIRC a Vulkan driver for Terascale GPUs is not possible because they don't support virtual memory, a required feature for Vulkan. It was something related to how GCN handles memory that Terascale doesn't
According to this answer by agd5f in an older thread, it should at least in theory be possible to work around these limitations.

Using OpenGL.
Now that would be the day...
