Xenia Git Release (August 18, 2026)

Xenia Git (2026/08/18) is an experimental Xbox 360 emulator that currently does not run games. The latest changelog includes various updates: optimizations, fixes for D3D12 and Vulkan related to blending, texture handling, and sample layouts. Improvements were made in GPU handling, including tessellated triangle support and clamping out-of-bounds vertex fetches. Memory management and kernel updates were also addressed, alongside adding support for dash 1746 and transitioning some code to C++20. Overall, the update focuses on enhancing performance and compatibility across various graphical features and functions.
