D9VK seems to perform the best, with Linux Native + GL Threaded coming in a close second at times, while straight up native Linux is slow asf, any thoughts as too why? The difference is almost half the fps on native vs D9VK

Actually. I've gone back and checked, D9VK renders correctly. The Linux native version is what is too bright and showing too much!

D9VK is pretty recent and might not be rendering 100% of everything that it should.

Just spit-balling here, but it's likely a poor DX -> GL threading implementation (seeing as how __GL_THREADED makes a big difference, and puts it close the DXVK version). I'm not an expert here, but Vulkan should be able to (in theory) fully implement the Direct3D 9 API and match the original game-code's threading logic in a gpu-driver agnostic way. OpenGL 3 API specs are apparently a bit ambiguous in some ways which has led to different GPU drivers implementing functionality (like when shaders compile, how state-changes get sent to the GPU, etc) in different ways.. which makes it harder to accurately emulate the D3D code. The remaining FPS difference is likely related to the game's native HLSL shaders being compiled to SPIR-V (Vulkan's shader byte-code), rather than a high-level translation to GLSL. Again, I'm not an expert on the state of Vulkan/DXVK's HLSL to SPIR-V implementation, nor Rocket League's native Linux port (or even if that's an actual port and not just a Wine warpper).. but in theory SPIR-V should more accurately encode the original HLSL's operations.

OpenGL on linux is single threaded. That's why. And it's also why the multi-threaded openGL closes the gap with Vulkan.

Can you test with the amd mesa-aco drivers? Or do you not own an AMD GPU?

As much as I would like to, I don't own or have funds to acquire an AMD GPU.

d9vk is not rendering a lot of details in the background. I guess that would explain it working faster than native+__GL_THREADED.

@@gordonsills actually it turns out the Linux version has the issues showing too much and too bright, D9VK rendering is correct against how it looks on Windows

@@gamingonlinux I saw your video first in my YT subscription feed and only then read the article. You made it really clear - great job overall :)

You should have put the FPS counters right next to each other, so it's easier to compare.

But then that makes it more difficult to compare with the actual video, there's upsides and downsides to all ways of presenting it. I can experiment with other ways for future videos though. Not something I do often so happy for feedback, thanks!

I don't buy games without Linux versions but I'm totally okay with devs just bundling proton and this video I think shows why. For me what matters is not if it's native but if it's officially supported.

Is this a replay/demo playback? Been scratching my head trying to figure out how you are able to get the exact same inputs and camera angles for each. I know it's got a replay save option but I haven't used it since early days because it never gave me the exact replay back (actually had the same issue with the replay in Super Smash Bros. on Wii U).

It is a replay

Correct, it's a replay. Never had issue with it :)

I am using openSuse Leap 15 and my game is lagging af sb who also had to deal with this issue?

Seems to be running awesome through Proton for the most part but every once in a while it crashes and says "Ran out of video memory. Exiting..." This is on Ubuntu 19.10 with a GTX 1070. Have you ever had that error in rocket league?
