In other words, when work begun on Vulkan for Godot, GLES3 support was not widespread or certain, but that is no longer the case.īecause of this, Godot 4.x will focus on both Vulkan and OpenGL ES 3.0.
On Web, GLES3 (WebGL2) suport is not present on Safari at this time (and support for it was uncertain for a long time), but it’s now finally in Technology Preview stage, which means it will be out and supported soon.On Mobile, the story is different but, as mobile phones keep coming out and old ones no longer work due to dead batteries/slowness/etc, GLES2-only devices are becoming very scarce (Only 10% at the time of this writing and less by the time Godot 4.0 launches).This hardware does not posses enough video memory to run a modern game engine, anyway. On Desktop, hardware that does not support GLES3 (or GLES3 via Angle, which is what Chrome uses to display WebGL) is extremely old.In the beginning, we wanted to support Vulkan alongside GLES2, which is why in the project manager you can see a disabled option for GLES2.Īs more work was poured into the Vulkan back-end, it became clearer and clearer that supporting GLES2 is not an option anymore. What version of OpenGL will Godot support? That said, given 4.0 has so much new code (the engine was rewritten significantly), it will also require a large amount of time dedicated to bug-fixing and stabilization even after stable. One of our main goals for the 4.x releases it to provide them in a timely manner, so you will not have to wait a whole year for it. OpenGL support will definitely be implemented by the time 4.1 is out, hopefully some months later. This took an enormous amount of work (more than two years, close to three at the time of release).
The renderer design and all resulting code had to be re-implemented entirely from scratch in order to support Vulkan and modern rendering techniques. OpenGL will most likely not be supported at the time Godot 4.0 is out. As the alpha of Godot 4.0 comes closer and closer, we wanted to spend some words to clarify the direction that Godot 4 has taken in regard of rendering back-ends.
