CodenameSwi v 0.3 is out for some time already. It does provide the following features: dynamic sky dome illumination and indirect illumination(GI or Global Illumination), Ambient Occlusion, dynamic wind that effects all sorts of vegetation, including trees, and supports D3D12 and Vulkan 1.1.
Below is the screenshot from within the 0.3, with WYSIWYG(What You See Is What You Get) all the time of editing. For the visuals like below it requires at 1280 by 720 pixels and around 34 to 40 frames per second a GTX 1060 or RX 580, but no RTX! No precalculation.
