    • Mode
      • Auto-detect
      • Automatically chooses the amount of threads to match the number of logical processors on your computer.
      • Fixed
      • Manually choose the amount of threads to use for rendering. This can be useful for example,if you want to use your computer while rendering, you can set the propertyto a thread count lower the amount of logical processors on your computer.
    • Tile Order
    • Tile size X/Y
    • The size of the tiles for rendering.
    • Progressive Refine
    • Instead of rendering each tile until it has finished every sample, refine the whole image progressively.Note that progressive rendering is slightly slower than tiled rendering,but time can be saved by manually stopping the render when the noise level is low enough.
    • Save Buffers
    • Saves all render layers and passes to the temp directory on a drive,and reads them back after rendering has finished. This saves memory (RAM) usage during rendering,particularly when using many render layers and passes. This can be read back in the Compositorand Image editor by using .
    • Use Spatial Splits
    • Spatial splits improve the rendering performance in scenes with a mix of large and small polygons.The downsides are longer BVH build times and slightly increased memory usage.
    • Use Hair BVH
    • Use a special type of BVH for rendering hair.The bounding boxes are not axis aligned allowing a spatially closer fit to the hair geometry.Disabling this option will reduce memory, at the cost of increasing hair render time.
    • BVH Time Steps
    • Split BVH primitives by this number of time steps to speed up render time in cost of memory.
    • Keep image data in memory after rendering, for faster re-renders at the cost of extra memory usage whenperforming other tasks in Blender.
    • 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 rebuild which reduces interactivity but renders faster.
    • Start Resolution
    • Resolution to start rendering preview at, progressively increase it to the full viewport size.
    • Viewport Resolution
      • Pixel Size
