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.

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)...

Recommended Physics Engine?
I donβt know of any books but here is the official documentation which includes an API reference. You can also find a lot of sample code snippets and examples on their GitHub.

C# Game engine - suggestions
On the other hand, PhysX is available under the MIT License and is both heavily used in games and also well documented with tons of sample code.

AMD Finally Opens Up Its Radeon Raytracing Analyzer "RRA" Source Code
The CPU implementation of PhysX is too, no reason you couldn't port that to run on AMD GPUs: https://github.com/NVIDIA-Omniverse/PhysX

Nvidia PhysX 5.0 is now open source
The LICENSE.md file on the repo doesn't mention BSD-3-Clause at all, it's just a copywrite notice that reads more like CC-BY than a software license. That's why I said it was weird.
Very! I just picked a random file: https://github.com/NVIDIA-Omniverse/PhysX/blob/release/104.0/physx/source/physx/src/NpArticulationJointReducedCoordinate.cpp

Bevy XPBD: A physics engine for the Bevy game engine
There is now also https://github.com/jrouwe/JoltPhysics which is used in Horizon Forbidden West.

Has anyone used Jolt physics engine?
Apparenty, this is a game engine used by Horizon Forbidden West and I was curious what you all think about this project: https://github.com/jrouwe/JoltPhysics
- 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

Rust β Are We Game Yet?
As far as physics engines go: Jolt currently seems to kinda disrupt the decade-long equilibrium, at least as far as I'm aware:

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.

Godot for AA/AAA game development β What's missing?
Would you rather they use Jolt Physics? https://github.com/jrouwe/JoltPhysics S&box is thinking of using this engine instead of Source 2's Rubicon. As they say, maybe someone could / would hook up Jolt as a GDExtension.
