AMD RDNA2 Vulkan: RADV vs. RADV+NGGC vs. AMDVLK vs. PRO Driver Benchmarks

What about compile times though?

In the cases where those are a problem, the goal is to improve them.

Community in open source development usually does not mean people working in spare time, but people outside of original developer.

Open Source Community means people coding (not working) in spare time for fun. Paid developers are paid developers. Funny how the terms have slowly been subverted. Subway workers doing kernel development? I'm not sure I get this lame attempt of a joke.

And before rushing to argue, remember the saying how "everyone is welcome to contribute", "you can patch everything", "you can do anything with open source" which people apply to open source/open source community - meanwhile absolutely most programmers are not capable of hacking GPU drivers since it requires a ton of skill and knowledge. And not programmers? No way on Earth you're skilled enough to contribute.

All I'm trying to say is that open source drivers vs closed source drivers means nada for the average Linux user since only a handful of people can actually fix issues in drivers and they do it only when a particular issue is critical enough. Go check i915/radeon bug trackers - hundreds of open issues and no one paying any attention to them since they are not widespread enough.

They need massive improvements in certain cases though. For example, Death Stranding compiles all it's shaders on the first loading screen, which finishes in about 2-3 minutes on RADV and amdgpu-pro, but takes more than 20 minutes on AMDVLK (!).

in commodore times you waited 20 minutes to play a game each time and you liked it.

In other words it's not "community" in any shape or form which means the whole idea of community driven GPU development is more likely a myth.

It sure seems like "gaming on linux" became a real thing when Valve started putting development dollars behind it. Before that it was a pretty lonely place.

Maybe I'll get a chance to buy one by Christmas 2023, let's hope bitcoin and so forth gets made illegal perhaps then if foundries pull their finger out.

That may be the case in some scenarios, but there are also a lot of upcoming features that are already largely present in LLVM that would be a lot of effort to implement in other compilers. Functions for example. There are trade-offs with all compilers.

More like W(h)ine'ing (or running better designed/supported/maintained APIs) on Linux

Proof that proprietary compiler is better than LLVM.
AMDVLK needs ACO.

Paid developers are part of the open source community. Everyone that participates is. The participation is the key point. Whether someone is paid or does it as a hobby is irrelevant.

As for complexity, GPU drivers are complex, but there are lots of other drivers and subsystems that are equally, if not more, complex. So they are not really unique in that sense.
