yup the AMD GL drivers on linux dont have this issue, and you'll see usually 30%-100% perf uplift

yup
the AMD GL drivers on linux dont have this issue, and you'll see usually 30%-100% perf uplift

IiDrmzIt I found out Unity spends like 30% of a frame just verifying if methods exist?

Something about finding if a particular MonoBehavior had Update/FixedUpdate etc

iDrmzIt•10/7/24, 7:36 PM

(note they were never overrides)

TechnicJelle•10/7/24, 7:36 PM

Horrific

LLyris the Kitori yup the AMD GL drivers on linux dont have this issue, and you'll see usually 30%...

Aqua•10/7/24, 7:36 PM

i see, it all makes sense now
i thought it was just being bottlenecked by thunderbolt lol

TTechnicJelle Horrific

iDrmzIt•10/7/24, 7:36 PM

It was never cached either

Lyris the KitoriOP•10/7/24, 7:37 PM

when 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

Aqua•10/7/24, 7:38 PM

yeah i remember reading that article, remember thinking that opengl was the superior api
haha, wrong

iDrmzIt•10/7/24, 7:39 PM

Gotta love companies trying to smack down open source competitors I guess

OpenGL on Windows v Linux

iDrmzIt•10/7/24, 7:39 PM

Sounds like MS was intentionally trying to hurt it

Lyris the KitoriOP•10/7/24, 7:40 PM

thats not whats happening
AMD just has a low-performace-high-correctness GL driver on windows

Lyris the KitoriOP•10/7/24, 7:40 PM

it wasnt built for gaming

iDrmzIt•10/7/24, 7:40 PM

Fair enough

iDrmzIt•10/7/24, 7:41 PM

Hmm, maybe that's why when I was like, 12, Minecraft had such poor performance on the computer I had at the time

Lyris the KitoriOP•10/7/24, 7:41 PM

microsoft 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

Aqua•10/7/24, 7:42 PM

minecraft is also written in java and is coded pretty poorly. it's probably more likely to be that than opengl

Lyris the KitoriOP•10/7/24, 7:42 PM

iDrmzIt•10/7/24, 7:42 PM

I mean yeah I've heard the horrors of memory management in Java

Aqua•10/7/24, 7:42 PM

stack allocation? what's that!

IiDrmzIt I mean yeah I've heard the horrors of memory management in Java

Lyris the KitoriOP•10/7/24, 7:42 PM

it's not even that

Perksey•10/7/24, 7:42 PM

I think it’s likely the code that’s contributing more to that

Lyris the KitoriOP•10/7/24, 7:42 PM

minecraft just sucks code wise

Perksey•10/7/24, 7:42 PM

I mean put it this way, Minecraft is the project notch used to learn OpenGL

AAqua stack allocation? what's that!

iDrmzIt•10/7/24, 7:42 PM

The amount of performance I would lose if I didn't have stack allocation would be incredible

Lyris the KitoriOP•10/7/24, 7:43 PM

in c#? prob not actually

Lyris the KitoriOP•10/7/24, 7:43 PM

gc is smart

Perksey•10/7/24, 7:43 PM

gen0 is basically free

PPerksey I mean put it this way, Minecraft is the project notch used to _learn_ OpenGL

iDrmzIt•10/7/24, 7:43 PM

I figured, as far as I know the UI was pretty strongly paired to the main renderer until recently

iDrmzIt•10/7/24, 7:44 PM

I guess I need to read up on the GC a bit more

Aqua•10/7/24, 7:44 PM

tbf, imo it's a balancing act. you can do that, have a horrible codebase, and make a game

Aqua•10/7/24, 7:44 PM

or do what i do and modularize literally everything and never get anywhere

Perksey•10/7/24, 7:44 PM

do things that don’t scale!

Perksey•10/7/24, 7:44 PM

if you’re at a point where you need to scale up that means you’re winning

Aqua•10/7/24, 7:44 PM

lol fairs

AAqua or do what i do and modularize literally everything and never get anywhere

iDrmzIt•10/7/24, 7:45 PM

But what if I want to use more or less functional approaches for everything, that won't go bad ~~I may have made a mistake~~

Aqua•10/7/24, 7:45 PM

i've made my music player relatively modular as well and now it's coming to bite me in the arse when it comes to implementing a proper API for it, cause it's too modular

Aqua•10/7/24, 7:45 PM

so i'm gonna scrap all the modules and the cli player and just dump it all in one project

iDrmzIt•10/7/24, 7:50 PM

I remember some of my old code being so interfaced out I couldn't track what was going where

Aqua•10/7/24, 7:52 PM

interfaces have their place, the api i've designed for my music player is almost entirely interfaces

Aqua•10/7/24, 7:53 PM

simply because it means you can fully interact with the player but it won't break existing plugins on an update

iDrmzIt•10/7/24, 7:55 PM

I mean yeah but I definitely overused them

AAqua after using the shadercross api for all of about 5 minutes i now 100% get the pu...

Lyris the KitoriOP•10/7/24, 9:10 PM

merged

the reason its so jank is that the API was originally built for use in FNA/MojoShader exclusively, and it just so happens that people like me picked it up and started improving upon it for use elsewhere

Lyris the KitoriOP•10/7/24, 9:10 PM

it wasnt even in the main sdl org originally

Lyris the KitoriOP•10/7/24, 9:11 PM

just a personal repo of flibitjibibo

Lyris the KitoriOP•10/7/24, 9:11 PM

Perksey•10/7/24, 9:25 PM

yeah the GPU API was literally just the FNA internal abstraction in the end

Perksey•10/7/24, 9:26 PM

it was similar enough to what icculus was designing and sped the process along

Rahkiin•10/7/24, 9:53 PM

They built the thing in what… 3 months?

yup the AMD GL drivers on linux dont have this issue, and you'll see usually 30%-100% perf uplift
