@altria Godot 3 is better from Godot 4, i think that is enof is no need to go on Vulkan, but engine is be written on GLSL for embedded device, al all the time speak the same, but if must engine be rewritten it can be on Open GL, yes ok Vulcan is better is modern lol, but no need that much money to spend on vulkan, and thanks God that is project success, Vulcan itself have problems and bugs, and its be easier to upgrade to gl, yes GLES is computable with some version with GL but no GL, and when time come done that...
