Performance

Reference

Panel

Properties region ‣ Performance

../_images/compositing_properties_performance.png

Performance settings.

This panel help you to tweak the performance of the compositor.

Render

Sets the quality when doing the final render.

Edit

Sets the quality when making edits.

Chunk Size

Max size of a title (smaller values give a better distribution of multiple threads, but more overhead).

OpenCL

This allows the use of an OpenCL platform to aid in rendering. Generally, this should be enabled unless your hardware does not have good OpenCL support.

Buffer Groups

Enables buffering of group nodes to increase the speed at the cost of more memory.

Two Pass

Use two pass execution during editing: the first pass calculates fast nodes, the second pass calculates all nodes.

Viewer Border

This allows to set an area of interest for the backdrop and preview. The border is started by Ctrl-B and finished by selection of a rectangular area. Ctrl-Alt-B discards the border back to a full preview. This is only a preview option, final compositing during a render ignores this border.

Highlight

Highlights the nodes that are being calculated by the compositor.
