Things would be easier if Linux had 90% of the market or at least had equivalent ABI stability to Windows, but unfortunately neither are true. On the other hand I think it is fair to say that the OSS drivers caught up fairly quickly after Catalyst Linux support was dropped.

3) The Linux graphics stack is a fragmented nightmare to support.

Sounds great but totally wrong. ATI supported development of open source drivers from Mach64 days through R200 and early R300. At that point we bought FireGL, picked up a closed source workstation driver as part of the deal, and started using that driver (which turned into Linux Catalyst) across the board for workstation and client.
While OpenGL performance issues I can understand, not having a plan to support X releases on the same day is just carelessness, imho.

Originally posted by gigaplex View PostAre you sure about that? I thought they were unified shader cores.
But looking over this article again it seems I might have been slightly confused about the cores, since not each one of them represents a queue by themselves. Instead, queues themselves are represented in hardware as "engines" or "command processors". Crucially, earlier NVidia cards did not have separate graphics and compute engines, so the work had to be interleaved (which wasn't a problem because of the guarantees of OpenGL/D3D11 I talked about), but Vulkan/D3D12 exposes the engines directly as Queues, so AMD GCN cards can schedule both types of tasks in parallel.
However looks like starting with Maxwell 2 (900 series), Nvidia does have separate graphics and compute engines, so async compute shouldn't give AMD such a big edge when compared against that hardware.Last edited by Ancurio; 10 September 2015, 11:02 AM.

OOOHH YES, Nvidia is "so" "good"...
Some might know this...BATTLEFIELD 2...Black holes on the ground
Doesn't matter if you play in XP, W7, W8 or Linux via WINE....Nvidia NEVER fixed it AFAIK...
OTOH, playing BF2 under AMD iGPUs...ZERO black holes EVER, no matter playing in XP, W7, W8 or Linux via WINE.
Funny fact ? It's a Nvidia game

For one, being part of AMD has put ATI on the path towards open-source. A slow, painful path but nonetheless the right one. No way ATI would have created OSS drivers as an independent company.
