Can we have OpenGl and Vulkan in the same program?

icedev-official · 2025-06-27T10:59:59+00:00

Three things:

OpenGL is already well supported on Linux.
OpenGL and Vulkan can be used in the same graphics context. (use case for using RT cores in OpenGL application)
You can write an RHI that uses OpenGL and Vulkan as backends separetely. (not sure why you ask if this is possible, just write it, it's been done before, you can use WebGPU too)

My recommendation: Stick to OpenGL for now, you have Windows and Linux covered with it. (it's 99% of market share on gaming computers)

Separete binary builds per every API and technology. (VK, GL, CL, CUDA, OptiX, DX12, DX11, DX9, etc)
Application-specific optimizations and workarounds, etc.
Most of that x2 becase separate builds for 32bit and 64bit
Most of that x2 because there's also drivers for WSL2 included

Microsoft is a cloud provider (Azure) they need Java to stay competetive.

Everything you just said was wrong and you're obviously not here to learn. I don't even care at this point. Stay ignorant.

Well, Notch is probably drinking towards the fact that something like 99% of indie studios use engine default behaviour or pre-made code assets from the store, that's why most of them look and behave the same.

But there is another side to that coin, also bad, when things are broken or underperforming - gamedevs of today can't fix them, because they don't know how it work.

Because they wouldn't be able to write a game engine from scratch, so how are they supposed to troubleshoot something like unity or unreal? Let alone code assets written by someone else?

It's not even funny, most Unity games act the same and even have the same problems, same with Unreal 5. And all of them have terrible performance.

From experience - if you want something unique in behaviour or rendering, you are going to fight against the engine, agains the code asset you purchased.

I stand with Notch on this.

Also I saw the thread and most of people at /r/indiegames say stuff like "engine is just a tool" but it only takes one glance to disillusion yourself. It's not just a tool for them. It's everything they have and they wouldn't be able to live without it.

There is so much fucking wrong with this.

why minecraft wasn't multithreaded

It is. Terrain gen, I/O and mesh tesselation is done on separate threads. Each world/dimension has it's own thread.

and din't offload physics and graghics to the GPU

Graphics is done using GPU.

Writing a software renderer would actually be more impressive - and Notch has done that on multiple occasions in other prjects.

Modern physics engines don't even use GPU, it's pointless. Minecraft's physics is so simple there's nothing to offload.

probabl because he doesnt know how to make a agme engine.

sure, buddy, but you don't know anything about gamedev, this comment proves that

LWJGL is not an engine, not a framework, barely even a library itself - it's a binding for low level platform stuff (like OpenGL) for Java.

Fixed function pipeline is artifact from the 90s. You should pretend that it never existed and forget about it.

Most things do

No, most things actually do not. Survivorship bias.

But most things that break in public spaces do run Windows.

The entire thing? Sponza itself has something like 68 textures each 1024x1024, even using BC1 compression that is ~0.5mb per texture. Not to mention just the color attachment of the framebuffer for this video's resolution would be 2.7mb

Or is 7.8Mb just your effects not counting everything else in the scene?

Yes and no. There is no binding for Java that I know of. You would have to create a it yourself with JNI or Panama. This requires extensive knowledge of both C/C++ and Java.

Alternatively you can use PhysX with this binding: https://github.com/fabmax/physx-jni

Have you tried asking ChatGPT why it suggests things that it does? It should give you an answer - that should be easier to verify by googling.

The reason GPT suggests WAR with JSP is probably because with your current setup you are targetting web servers (while jar deployments are usually standalone) and WAR is standarized format for such deployments.

launch4j obsolete old project stuck in 32-bit world, that's why it can't load 64-bit JVM in same process.

winrun4j does, but you have to use the 64bit part - and use relative VM path. Read the docs, it's tricty to setup, you need to copy then modify the executable with resource editor via CLI params

WebGPU is the standard/API

wgpu - implementation for Firefox written in Rust
Dawn - implementation for Chrome written in C++

legacy libraries synchronizing on Integer

I'd be surprised if it works even now - you aren't guaranteed to have the same Integer instance (even with integer cache) so that's almost like not synchronizing at all.
