IMaybe the rare Godot
Adon't quite recall, amd did perform significantly worse in opengl in general, although it's hard to know how much of that is down to thunderbolt 4
TYeah unity and Godot mostly
LAMD OpenGL on windows is nerfed against linux because their windows GL drivers were built for workstation use, not gaming
Aoh huh
IThis makes me wonder with Unity 7 apparently going to CoreCLR how that will affect things
TSame
II also wonder if they're going to be deprecating a bunch of things as part of that fairly significant move
TI don't particularly care for Unity (anymore) (though I never much did) but I gotta say, finally their promises are sounding like they come from having listened to what the people actually want
Athat would explain why the disparity was massive on amd then, i couldn't even reach 60fps while rendering like 1000 cubes (i know a lot of that will also be due to my inefficient rendering system), while it reached like 100 on my laptop's significantly less powerful nvidia gpu
TI hope so
IOne of my big criticisms of Unity had to come down to it's tech debt and also the rampant use of reflection
TMhm
II found out Unity spends like 30% of a frame just verifying if methods exist?
Lyup
the AMD GL drivers on linux dont have this issue, and you'll see usually 30%-100% perf uplift

ISomething about finding if a particular MonoBehavior had Update/FixedUpdate etc
I(note they were never overrides)
THorrific
Ai see, it all makes sense now
i thought it was just being bottlenecked by thunderbolt lol

IIt was never cached either
Lwhen valve initially ported L4D2 to linux natively back in like 2016, the perf on top of the line AMD OpenGL on linux was beating top of the line NVIDIA D3D9 lol
Ayeah i remember reading that article, remember thinking that opengl was the superior api
haha, wrong
haha, wrong
IGotta love companies trying to smack down open source competitors I guess
L?
IOpenGL on Windows v Linux
ISounds like MS was intentionally trying to hurt it
Lthats not whats happening
AMD just has a low-performace-high-correctness GL driver on windows

Lit wasnt built for gaming
IFair enough
IHmm, maybe that's why when I was like, 12, Minecraft had such poor performance on the computer I had at the time
Lmicrosoft has a vested interest in keeping GL running well forever into the future, thats why win11 comes bundled with mesa to do GL->D3D12 translation
Aminecraft is also written in java and is coded pretty poorly. it's probably more likely to be that than opengl
L^
II mean yeah I've heard the horrors of memory management in Java
Astack allocation? what's that!
Lit's not even that
PI think it’s likely the code that’s contributing more to that
Lminecraft just sucks code wise
PI mean put it this way, Minecraft is the project notch used to learn OpenGL
IThe amount of performance I would lose if I didn't have stack allocation would be incredible
Lin c#? prob not actually
Lgc is smart
Pgen0 is basically free
II figured, as far as I know the UI was pretty strongly paired to the main renderer until recently
II guess I need to read up on the GC a bit more
Atbf, imo it's a balancing act. you can do that, have a horrible codebase, and make a game
Aor do what i do and modularize literally everything and never get anywhere
Pdo things that don’t scale!
Pif you’re at a point where you need to scale up that means you’re winning
