My `vulkaninfo |grep pipeline` output, still on Mesa 22.2.4:

Don't know why it lists the extensions multiple times.

Ahh nice, it is in then. Maybe its just experimental and needs variable?

edit: i think i found. It seems to be experimental indeed `RADV_PERFTEST=gpl`

Still no graphics pipeline library? :sad:
nvidia has had this since june in the vulkan dev drivers and now few months on stable and beta drivers
this is really a gamechanger with the shader stuff when it comes to DXVK.

Quoting: CorbenThey switched to EGL, nvfbc (which I'm also still using via OBS 27 as it's awesome, both performance-wise and usability-wise) needs GLX though. And they don't want to maintain GLX anymore.

Yeah i heard that, but why switch from a working solution to something that breaks plugins :(

Quoting: CorbenThe OBS Linux maintainers said though, they've put in a lot of effort to make xcomposite capture much better and more performant. They advice to use windowed fullscreen for best results. Haven't tested it yet, but as other plugins are also dropping support for older OBS versions sooner or later, I'll probably upgrade at some point.

Or nVidia implements nvfbc for EGL in their driver... ha, yeah, I know... but we can dream, can't we!

Xcomposite is pretty similar to perf with nvfbc to be honest, thats not an issue really, but i have to select what window i want to record then every time and if i want to record whole desktop, its sad story. Fullscreen capture (XSHM) is just epicly slow when you launch a game on the desktop. nvfbc was performant in all situations.

Quoting: GuestGreat now they need to fix the Xid 109 error on 525.53 in some DX12 via VKD3D games and I am all happy :D

Hmm Can you name games with that issue. So far from my testing only issue is Serious Sam Siberian Mayhem (Vulkan) has some shadow flickering on trees. Rest of the games i have tried have had no problems, DXVK, VKD3D, Vulkan or OpenGL. Also is that issue reported to nvidia or vkd3d-proton to investigation?

What games i have tried with this driver
DXVK: Apex Legends, Shatterline, Max Payne 3, F.E.A.R. 2, WRC 10, Warhammer Online Return of Reckoning, Warhammer Vermintide 2.
VKD3D: Horizon Zero Dawn, Cyberpunk 2077, Metro Exodus Enhanched
Vulkan: Valheim, Splitgate, Serious Sam Siberian Mayhem (The shadow flicker)
OpenGL: Sector's Edge

edit: theres no Xid 109 even listed, the list ends with Xid 92 lol https://docs.nvidia.com/deploy/xid-errors/index.html [External Link]

They still haven't reversed the commit that broke NvFBC it looks like :(
Still using the v27 because of that. I will have to look for alternatives soon i guess

Hmm thats indeed confusing. We now have 525.53, 520.56.06, 515.49.25 and now this?

525.53 - newest beta
515.49.25 - latest vulkan dev driver
520.56.06 - Is what? newest stable?
515.86.01 - latest long term stable?

Im currently using 525.53 since its release and its been working wonderfully. no issues to report.

So far the driver seems very good. Serious Sam: Siberian Mayhem has some shadow flickering on trees though with this driver though. All the other games i play work perfectly. It also looks like this driver uses less video memory with x11 than it used before and the GPU downclocks more easily with 2 high refresh screens also. Overall looks like nice improvement.

-Power Consumption numbers look neat
-Card size looks good also compared to Nvidias massive card.
-Pricing looks to be very good, if the performance is up there close enough.
-AV1 encoder looks neat.

-8K gaming figures are super stupid. Ultrawide 8K is not 8K really.
-Every benchmark had FSR enabled but i didn't see any mention in what mode.
-There was no comparison with the competition, so i guess they don't really have that sort of performance.
-Raytracing performance still didn't look too good. Improvement from last gen at least.

Lots of hype words like worlds first, unprecedented etc, but thats how those events are with every other manufacturer also.
Lets wait and see what the third party benchmarks will look like. Hopefully it's competitive enough.

Quoting: XpanderNot much perf loss with that, but the Screen Capture (XSHM) is awful when GPU is nearly fully utilized, whole desktop starts to lag. NvFBC was the best to record entire screen without any significant perf drop.

On my NVidia I use gpu-screen-recorder [External Link] in replacement of NvFBC as it gave me a huge performance boost.

I used to use gpu-screen-recorder but it had 2 issues for me. It made the video files with variable framerate, which caused issues with kdenlive to edit those. Audio went out of sync. Though i think thats fixed now. The second thing was the missing multi-track audio recording. I like to capture game, desktop and discord as multiple audio tracks, which can be easily done with OBS and its pipewire plugin.

I'll give gpu-screen-recorder another shot at some point.

No info about when Nvfbc will be supported again?
This was the stupidest change ever made with v28. Breaking nvfbc :(
Xcomposite is fine for window capturing. Not much perf loss with that, but the Screen Capture (XSHM) is awful when GPU is nearly fully utilized, whole desktop starts to lag. NvFBC was the best to record entire screen without any significant perf drop.
I'm still using the downgraded v27 because of that.
