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.

- Project Alice (Victoria 2 open-source clone) December Update (nearing 1.0 release)
- July update and PUBLIC DEMO for Project Alice

Does anyone know any good open source project to optimize?
Currently I am part of a team working on an open source game (https://github.com/schombert/Project-Alice) that intends to lean heavily on vectorization for performance, since it is a strategy game that has to work with a decently large amount of data, by the standards of a game at least. We have things set up so that most of the data is stored in something like the struct of arrays pattern and we have some machinery in place for doing vectorized operations on it. But obviously we could benefit from a specialist. On the other hand, perhaps a game is not serious enough for your work, and there is a lot of things going on in a game that are probably irrelevant for your work.

C++ Show and Tell - June 2023
Well on our way to recreating the game Victoria 2 in C++ from scratch (i.e. we didn't use an existing game engine). https://github.com/schombert/Project-Alice

OpenVic2 Has a Map! (Full update on the project)
It looks like it will be done much sooner then. They have done a lot so far https://github.com/schombert/Project-Alice/blob/main/docs/Devlogs/may/may.md
- May 2023 update for Project Alice (the Victoria 2 "retro clone")
-
Next CK3 dlc just gave me the vibe
a small search resulted in this development blog from 3 days ago (after one a month ago)
- April 2023 update for Project Alice (the Victoria 2 "retro clone")

I have just gotten victoria 2, any tips for begginers?
Enjoy: https://github.com/schombert/Project-Alice/blob/main/docs/rules.md It isn't 100% complete, but it is most of the way there

OpenVic2 vs Project Alice
Project Alice is a continuation of a previous effort by u/schombert to create an open source Victoria 2. He is rebuilding the project in c++ with opengl and can be found here. I'm not sure on actual implementation details and any modding / multiplayer details

Blaze: A High Performance C++ Math library
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...
- Looking for specific pre-Microsoft Havok Physics SDK version (2013, 2014)
- Software for Mechanism Analysis

Does anyone know any good open source project to optimize?
I suspect most C++ physics libraries like Box2D (https://github.com/erincatto/box2d) or Bullet3 (https://github.com/bulletphysics/bullet3) could really benefit a lot from SIMD.
- After months of work, I'm excited to share the first release of Godot Jolt, an extension that integrates the Jolt physics engine into Godot, demonstrated using GDQuest's RoboBlast

X4's Upcoming Multiplayer Features Are a Huge Step Forward
No, they replaced Bullet with Jolt. That is considerably more than "some adjustment", regardless of what you think of the result.

Brick Breaker
Vulkan graphics via Intel GVK, and physics via Bullet

Ive been programming for four years and I told my dad to watch long videos and complete your own projects to learn most efficiently. He thinks he’s ready to tackle any project after a ten minute video…
The first two have a bunch of great examples, and I’m tying them together by refactoring some of the THREE examples to fit the ECS paradigm defined in AFrame. then upping the ante by adding physics using AMMO, which is more challenging since it’s only a partial implementation of Bullet, and already poorly documented (yet popular) physics engine.

Their music is just too good
Plus, SM uses a system called bullet physics, I imagine this would be rather complex to rework into a modern engine such as Unreal or Unity (after all, the majority of performance issues come from the physics engine rather than the graphics engine)

Is anyone working on more effecient HDT-SMP?
The physics in HDT-SMP are actually being calculated outside of Skyrim's engine with Bullet, an open-source physics engine. So this isn't some limitation of Skyrim's engine.
What are some alternatives?
retro-game - a 2d game made in SFML and c++
PhysX - NVIDIA PhysX SDK
DiscordCoreAPI - A bot library for Discord, written in C++, and featuring explicit multithreading through the usage of custom, asynchronous C++ CoRoutines.
Box2D - Box2D is a 2D physics engine for games
key-manager - A desktop app for password management and creation, developed using Qt.
CHRONO - High-performance C++ library for multiphysics and multibody dynamics simulations
OpenVic - Main Repo for the OpenVic Project
