Blender Optimization Leads To Twice As Fast Performance With CPU Bottlenecked Scenes

Written by Michael Larabel in Free Software on 24 March 2026 at 09:25 AM EDT. 8 Comments
Proposed code for Blender's EEVEE engine can lead to both the OpenGL and Vulkan performance doubling in instancing-heavy scenes that are CPU bottlenecked.

A pull request was opened last month for Blendr's EEVEE to implement HandleRange support as part of the instancing optimizations support for this real-time rasterization engine.

This is part of a broader effort since 2024 to reduce the overhead of the drawing logic.

The main takeaway of the pending pull request is the ability to see twice as fast performance.

The code is currently under review and follows the recent Blender 5.1 release.
