目前gles后端是好用的，但是vulkan后端无法正常运行

新建一个Forward+项目就可以复现了

能否提供一个可执行的文件 或 从 Godot 构建 rv64 可执行文件的步骤？

您好，项目在这里

sudo apt install curl p7zip-full
curl -fsSL https://gitee.com/openkylin/godot-riscv/raw/master/install.sh | bash && source ~/.bashrc
rvgdvm start 4.4.1

vulkan 后端目前在 weston 上可以用，但在 mutter 上还需要进一步适配。

5

有什么方法吗？需要修改什么

使用 vulkan 后端需解决 zink+vulkan 渲染 OpenGL 通路问题。目前建议使用 OpenGLES 后端，使用 zink+vulkan 会有一定的性能损失。
