Open 3D Engine O3DE 25.10 Brings Build Improvements, Vulkan & Linux Fixes
It's been four years now since the Open 3D Engine was born out of Amazon's Lumberyard project and hosted by the Linux Foundation. Today marks the release of the Open 3D Engine "O3DE" 25.10 release with the newest features and fixes for this cross-platform game/graphics engine.
The Open 3D Engine 25.10 release has re-engineered the installation process to provide more efficient building of this engine, an improved debug experience with lower memory use and faster build times, support for the C++20 programming language standard, and other build improvements.
With the build improvements, the installer packages for O3DE 25.10 are around 26% smaller on Microsoft Windows and around 40% smaller on Linux.
O3DE 25.10 also has a number of Linux-specific fixes, several Vulkan fixes, and some feature work like masked occlusion culling now working on Linux and re-enabling the OpenXR gem.
O3DE 25.10 can be downloaded from GitHub. Release notes and more details on the O3DE 25.10 engine release via o3de.org.
