    Jolt Physics

    A multi core friendly rigid body physics and collision detection lib

    A multi core friendly rigid body physics and collision detection library suitable for games and VR applications, used by Horizon Forbidden West. So why create yet another physics engine? First of all, this has been a personal learning project and secondly I wanted to address some issues that I had with existing physics engines. In games we usually need to do many more things than to simulate the physics world and we need to do this across multiple threads. We therefore place a lot of...

    lsfg-vk

    lsfg-vk

    Lossless Scaling Frame Generation on Linux

    The lsfg-vk project is a Vulkan layer developed primarily by PancakeTAS that hooks into Vulkan-based applications to enhance rendering by generating additional frames using the Lossless Scaling frame generation algorithm originally associated with the Lossless Scaling project. Instead of relying on driver-specific or hardware-accelerated upscaling, this layer intercepts Vulkan API calls and injects frame interpolation on the fly, effectively producing smoother motion in supported games and...

    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    ...Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. Its modularity and open nature make it attractive for indie developers or hobbyists who want to avoid heavyweight engines with lots of built-in assumptions. Even if the engine may not yet rival more mature engines in features or polish, its openness and design philosophy can offer an appealing balance between simplicity and flexibility.

    Modified source engine (2017) developed by valve and leaked in 2020

    The Source Engine repository under that particular GitHub user appears to be a custom (or forked) version of a game engine — likely an engine derived from or inspired by the classic Source engine lineage (or at least the name evokes that lineage). However, publicly-available documentation, community support or clarity about the project’s scope and maturity seems limited: the repo does not clearly advertise a full engine release or wide adoption. As such, it feels more like an experimental or...
