Blender 3.0 is a massive update that introduces numerous new features and dozens of enhancements to the 3D modeling software. One huge change in this release is the fact that Blender now uses the Vulkan next generation graphics and compute API by default for better graphics performance with lower power consumption.
Another big change in the 3.x series is the replacement of the BGL module with the GPU module. Also, Blender’s Cycles received a major revamp that leads to significantly improved GPU rendering performance and interactivity in Blender 3.0.
