  • “It is not expected that Vulkan will become the default backend in Blender 5.0. The reason is that OpenGL drivers are able to offload GPU memory to CPU RAM. Vulkan being a low level API doesn’t. Reports have been coming in that more users face this limitation and that we need to solve it. There are multiple ways how to solve it and with their own draw-backs. We want to experiment upcoming week with sparse memory. According to the Vulkan specs it allows to replace the GPU memory behind a handle (image or buffer) using a queue command. When this happens we could split the render graph and perform the uploading/synchronization that are needed.”
