Along with a Vulkan renderer there is also now support for OpenGL ES 2.0/3.0 as well as DirectX via libANGLE and then Apple Metal by way of MoltenVK to use the Vulkan renderer.īesides the Vulkan renderer for this two decade old RTS game, v4.0.0 also has new factions for the multiplayer / skirmish mode, higher resolution terrain textures, a new music manager, smarter AI bots, API enhancements, smoothness improvements, and hundreds of bug fixes. Most notable with Warzone 2100 v4.0 is the introduction of a Vulkan renderer to complement its existing OpenGL rendering support. Warzone 2100, the real-time strategy/tactics game that was originally released in 1999 as a proprietary commercial game only to then be made open-source several years later, is out this week with its version 4.0 milestone.
