Render ‣ Performance

These settings are mainly useful to developers and can be accessed by enabling the Cycles Debug.

OptiX Flags
Native OptiX Curve Primitive

Use OptiX curves API for hair instead of custom implementation.

Viewport BVH Type
Dynamic BVH

Objects can be transformed, added and deleted interactively, at the cost of slower renders.

Static BVH

Object modifications require a complete BVH rebuild which reduces interactivity but renders faster.
