Very unexpected that they made nvfbc on wayland an interface to desktop portal

Quoting: pete910Why not include AMF too while they where at it? I know I can use va-api but it sucks compared to AMF.

AMF uses Vulkan video. So better ask, why not include Vulkan video directly to OBS?

Most people use radv and vulkan video encoding is experimental right now in mesa, it's behind a flag and if you try to use it even with the most basic vulkan video encoding sample it will crash your computer (I tried it myself). Vulkan video encoding works fine with nvidia though (at least with hevc).

Vaapi and amf are also already implemented in ffmpeg so obs gets them "for free". Ffmpeg doesn't support vulkan video encoding yet (primarly because amd is lagging behind in their implementation so the implementation in ffmpeg and gstreamer has been delayed as well).

Steams game recording feature is unfortunately not hardware accelerated yet on nvidia, it doesn't even use nvenc (it uses libx264). It's hardware accelerated on amd though (at least on steam deck).

"When using AMD FSR 3 and FSR 3.1 frame generation, it is highly recommended to be always running at a minimum of ~60 FPS before frame generation is applied for an optimal high-quality gaming experience, and to mitigate any latency introduced by the technology"

Quoting: Vortex_AcheronticUh nice! Does someone happen to know if it uses proper HW acceleration across GPU vendors and drivers or does it run in software?

A lot of these questions are answered on their new page about it:
https://store.steampowered.com/gamerecording [External Link]

At the moment this page is incorrect. On amd (on steam deck at least) it is hardware accelerated (capturing on the gpu and encoding with vaapi) but on nvidia on linux desktop its fully software encoded. You can see this if you run steam from the terminal and check the terminal output, it says that its using libx264 and not nvenc (and you can also check video codec engine usage in nvidia settings where it says 0%).

Quoting: LoudTechieA. Just because it's 10 years old doesn't mean it's legacy. In system development 10 years is pretty young.
B. Because "legacy" is legacy, because it has proven to be useful.
C. Because standardization, basically any standard is just legacy support for really popular systems.

It's legacy because every modern graphics api is designed with explicit sync in mind (such as vulkan) and every other operating system uses explicit sync. Isn't wayland supposed to be forward-thinking instead of choosing decades old solutions that are no longer the best solution? But besides that, why should nvidia implement something that is guaranteed to get replaced anyways? wayland, amd and intel should just step forward and do the inevitable instead of wasting time with an inferior solution.

Quoting: pleasereadthemanualI'm glad NVIDIA pushed the entire Linux Graphics Stack to implement explicit sync too. It makes all of our desktops better.

They dragged us down by 10 years, without supporting GDB, wayland, etc, amd intel always had that figured out, except nvidia, this is a good solution yes, but because of their lazyness we aren't using wayland from default since years

Why are you saying its because of their lazyness and not amd, intels and wayland lazyness? why should nvidia implement something that is legacy everywhere else and amd/intel not implement something that has been the standard for over 10 years and that they have already implemented on windows?

I wonder if nvidia is ever going to fix the issue with cuda power usage when nvenc is used.

Quoting: ShabbyXNVIDIA is testing the waters with open source, and I'm sure they'll have more to come. I can only hope they have a good enough experience that they won't feel it's too hard and give up!

It's not something new for nvidia. Their nvidia drivers for their other devices such as nvidia tegra are open source. It's only their old desktop/laptop nvidia driver that is not open source.

Quoting: nenoroI wonder why bsd restrict this function ?

openbsd does that in all programs. Instead of relying on software being perfect with no bugs, if there is a bug and somebody takes advantage of that (a malicious actor) then it has restricted access, minimizing the impact of the vulnerability. Its kinda like what browsers do in tabs, on linux too. If there is a browser vulnerability and a website with javascript tries to use that to do malicious things then the tab is automatically killed by the kernel.
