NVIDIA 361.16 Beta Driver Now Includes Long-Awaited GLVND

[pinguinpc]

At simple seek seems equal in wine, gpu use and temperatures seems similar to 358.16 too

And the relation of what you just said to Wayland is?

I think it has to do with the OpenGL ABI now being decoupled from GLX, which may make certain things easier.

This is just a long-overdue ABI overhaul, nothing new performance-wise (that would require removing things like context binding). But you probably implied you knew that with that smiley.

Anyone know how long this took to release? I am pretty sure it was presented at least 2 years ago, with radio silence (at least for those not involved) ever since then.

The main difference is that libglvnd allows both drivers to coexist. That means you don't have to blacklist and overwrite one to use the other. It's much cleaner, and you can switch between the two on the fly (in fact both can run at the same time on different screens if you want).

Sounds like Nvidia's approach is much better than Debian approach.
Those features Nvidia's approach allows are really a step up in flexibility and options compared to the Debian approach.

GLVND is definitely a step in the right direction.

It will most likely allow rendering OpenGL content (games, ...) on nvidia GPU and display the rendered image on a display connected to an AMD APU or to an Intel CPU.

The new system is a giant leap in the right direction.
But I would like to see a system offering similar functionality without any library such as libglvnd.

Linux can use some improvement in how it deals with API's and hardware implementation.
For software using API's such as OpenGL, which might have multiple backends.
The best thing to do is to implement inversion of control for resolving dependencies.
Have some dependency management for software, API's and hardware/software implementations offering API's and software (user applications) using the API's and it's implementations.

Did they do something to nvidia-smi?

Well, Nvidia's approach only has to accommodate video drivers.
Debian's approach lets you keep several versions of gcc, python, java and whatnot installed and easily (in theory, at least) switch between them.

The question to ask is then, if Nvidia's approach would be done on those other projects, how would it compare to Debian's approach.
Don't compare two different approaches with different scopes, without making sure you understand the difference between approach and scope.
I would like to see some sort of Dependency Injection Management system instead for everything.
