Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Which engine/program do you use?
Urho3D, an open source C++ game engine.
-
C++ Game Engine?
I believe Urho3d supports MacOS (see 'about' page on the legacy website).

I'd like to learn game engine development - where to even start?
If you're literally clueless your best bet is to first start learning with an existing clean-ish engine like Urho3D implementing whatever feature/screwing-around or start with a framework like nVidia's Donut that gets you your window and basic rendering in place.

Game Engine Renderer Architecture regarding UI
I would recommend tracking through the gist of Urho3D's batch/batchqueue stuff as it's a reasonable setup that is very intelligible (if you speak C++), it's not the greatest thing on the planet but you should be able to roughly grok it in an afternoon. Doing draw batch-pumps greatly streamlines the final drawing code.

Game engine for programmars
You could try Urho3D or its newer fork rbfx.

Preferred game engine
I use an engine called rbfx which is a fork of the Urho3D engine. A lot of it is just the fact that I've been using it for over a decade, so I am comfortable with it. I'm a programmer, not really comfortable with integrated editor engines such as Unity or Godot, and the easy C++ extensibility of the engine appeals to me. Plus it's decently powerful, and well supported on a lot of platforms (I build for Windows, WebGL, and very occasionally RPi for the most part) and is open source to satisfy that stubbornly libertarian side of my character.
-
What is the lightest C++ 3D game engine for Linux?
You might be interested in Urho3D.
-
I need a REALLY lightweight engine
If you don't mind something experimental, there is a C# version of Urho3D that is in fairly active development. There is also a C#-scriptable branch of the Urho3D fork, rbfx, located here. Both of these projects are still pretty in-the-works, but are still pretty usable.

Lag Is Never Where You Want It... Or Don't Want It
Reading ebiten docs and source code they very clearly state that writing RGBA bytes to an image is slow, and shouldn't really be done every frame, at least many times per frame. This is where I thought my performance was being lost, and it sent me looking for answers for ages. Turns out, I was wrong and right.

Making Games in Go for Absolute Beginners
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.

Is there a love2d for c++?
What about learning Go with Ebiten? Or Rust with Bevy?
-
What would be the closest thing to Unity/Unreal C#/C++ for Go to create games/animations/visual work?
Actually, there is a game engine in Go. Ebiten(gine) is actually really popular and has already been used for a few games in production

Mac + opengl
I noticed a similar issue when I got my MBP with the framebuffer not matching the window size and this has to do with the DPI settings. This GitHub link helped me understand the issue better and I hope it can be of assistance to you https://github.com/hajimehoshi/ebiten/pull/1811

crten - a small tool to view your pixel art with a CRT screen effect
This program also demonstrates how great Ebitengine is and how you can port GLSL shaders to it almost 1 to 1.
