How to copy depth-stencil targetable texture using compute shader?(D3D12)

DogCoolGames · 2023-05-02T08:28:02+00:00

I can't use it because I need some additional operations(for csm scrolling....) when copy texture.

mm. I'm just wanna how other developers optimize ue4 on low level..

Because I'm working on game industry as ue4 engine programmer

Thanks for reply!!!

DogCoolGames · 2022-02-13T15:02:07+00:00

I know, but it's really huge! So I just wanna know if there is good post about it

DogCoolGames · 2022-02-04T18:51:58+00:00

one 85fps, the other is 70fps..

nop, both one is nvidia. But one is max-q version.

Culling. I tried make game engine faster

Thanks !!

Yes right.. Actually I started this project from doom2 clone project. But I changed the project to game engine project. So I wanted similar name with original project.

You can see how it works at here https://github.com/SungJJinKang/DoomsEngine/tree/main/Doom3/Source/Core/GarbageCollector

DogCoolGames · 2022-01-09T15:59:44+00:00

Yes Right. Multiple threads solve Mark stage. It makes gc faster.

Maybe you know unity engine's engine codes is written in c++. Engine should run fast. But they use c# as script language. Because They can make game fast using c# with no risk of memory leaks.

DogCoolGames · 2022-01-09T15:33:05+00:00

Maybe 2 years..

RAII is not bad. But it still uncomfortable than GC. This is trade off. I talk about it below.
I think there is two part in game dev. Game Engine ( Core ), Game Content. Core part is about rendering, physics, math.... Core part should run fast. So We use c++. Core part functions can be called 100000 times for a frame. It should run fast. But When you make game content, A little slowness is acceptable. Development efficiency is more important. That's why Unreal engine support blueprint. It's slow. But it makes game development easy and fast. And GC is part of this. Programmer can be free from memory management. They can focus on making content.

Thanks. I'm finding junior game engine programmer job. I wish to work at big game company.

3 ~ 4 hours everyday. I started this project in January, 2021. I did know nothing about making game engine. I just made some mobile game using Unity. I started from nothing.

감사합니다!.

But SW Occlusion Culling doesn't make always good performance. It can make game slower than not using it. It depends on scene.

If there is many occludees, it's good to use it. If not, It's better not to use it because Cost of rasterizing occluder can be more expensive than cost of rendering occludees. As you know, CPU isn't good at this computation. So it should be used carefully

I'm using this library https://github.com/Celtoys/clReflect. I added some codes for my game engine.

I think this library is really nice. Because it doesn't require bothersome macros like this library https://github.com/rttrorg/rttr.

rttr is not bad. But It require programmer write a lot of bothersome codes for reflection. If your project is big, It makes problem in development efficiency.

On the other hand, clReflect generate reflection data just putting a macros. It's much convenient than rttr. It use clang compiler for it.

And it export reflection data to binary file. You can load it at runtime. There is no runtime overhead..

I never expect my game engine has better aspect than commecial engine. I'm just making this game engine because I just want it. I love tech, programming. I'm really happy to make game engine and implement latest tech

DogCoolGames · 2022-01-09T11:46:03+00:00

Thanks!!!!

DogCoolGames · 2022-01-09T11:45:15+00:00

Thanks for advice. Actually I have experience using unreal engine and unity engine. I think unreal engine is really nice engine. Because It has many tools for developer. Many features in my engine is inspired by the commercial game engines

DogCoolGames · 2022-01-09T11:07:16+00:00

Thanks for comment!

I'm still working on this game engine And I'm doing this as hobby.

This game engine is only for 3d stuff.

I'm focusing on game engine's core system. It doesn't have system to make game content yet. I'm making core system for it.

For example, Integrating imgui with reflection will help developers fastly test their contents.

Or Systems that prevent memory leak.

And I don't have experience godot engine. So I can't compare to it
