The CRYENGINE 5.4 Preview has been released and it comes with something truly interesting: Vulkan support.From their announcement:They note that the Vulkan renderer is currently in Beta, so it's not entirely finished and stable. However, it's fantastic to see one of the other major game engines to support it. This might help Vulkan adoption some more, but CRYENGINE isn't as popular as it once was that's for sure.In the next full release, they're also planning full source code for the Sandbox Editor.See the full details here Thanks for the tip Raven.
