The implementation of Vulkan in Blender has represented a significant advancement in the software's performance. Initially introduced in version 4.1 to improve visualization in the interface and the viewport, this rendering engine continues to evolve with improvements in speed, stability, and compatibility.
Faster Scene Loading
Thanks to Vulkan optimization, loading times in Blender have been considerably reduced:
- Up to five times faster on a cold start.
- Up to two times faster on a hot start.
This means users can work with complex scenes much more fluidly, reducing waiting times and optimizing the workflow.
Advances and Limitations in Cycles
Vulkan has also been integrated into the visualization of the Cycles engine, allowing the rendered image to be displayed directly in Blender's interface. However, the engine itself does not yet fully leverage this technology, as its full implementation is still in development.
Factors to Consider
- Vulkan improves real-time visualization, but the final render in Cycles still depends on other processes.
- According to Blender's official documentation, a date for its full implementation in the rendering engine has not yet been determined.
Compatibility with Older Hardware
One of the most notable aspects of Vulkan is its ability to run on older graphics cards. On Windows and Linux systems, this technology is compatible with GPUs such as:
- NVIDIA GeForce GTX 900 (released in 2014).
- AMD Radeon 400 (available since 2016).
This allows more users to access performance improvements without needing to upgrade their hardware.
A Technology in Development
Despite its advances, Vulkan remains an experimental feature in Blender. Currently, some key features are still not supported, including:
- OpenXR: technology used for virtual reality experiences.
- OpenSubdiv: system for advanced surface subdivision.
- Animation improvements: additional optimizations are required for full implementation.
"Vulkan is redefining speed and stability in Blender, but its development continues to reach its full potential."
Blender 4.4 and the Compositor Rewrite
In addition to Vulkan improvements, Blender 4.4 has introduced an optimization in the CPU Compositor. Among the most relevant changes are:
- Increase in efficiency of key nodes, accelerating image processing.
- Renewal of the Glare node, used for glow and flare effects in rendered images.
These advances contribute to Blender continuing to evolve as a more powerful and accessible tool for 3D artists.
