D7VK 1.4 was released today, February 25, 2026, bringing further enhancements for old Direct3D versions on Vulkan under Linux. D7VK is an open-source project that began by implementing Direct3D 7 APIs on Vulkan, later expanding its scope to include Direct3D 6 and Direct3D 5 support. The 1.4 release "continues to enhance the support for these older D3D versions on Vulkan under Linux," according to Phoronix. This update improves the ability to run classic Windows applications and games that rely on these legacy Direct3D APIs on modern Linux systems by leveraging the Vulkan graphics API.
