Godot is an excellent open source cross-platform game engine,It currently supports RISC-V, but currently does not support VF2 GPU devices, and the editor can only run through OpenGL and vulkan
Hopefully, Vulkan will be officially supported
Here I have submitted an issue to the Godot community, if you are interested, you can follow up
Does not run on the RISC-V64, VisionFive2 SBC, · Issue #80676 · godotengine/godot (github.com)
