# lodAverage A Boolean value that specifies whether the GPU can use an average level of detail (LOD) when sampling from a texture. ``` var lodAverage: Bool { get set } ``` ## Discussion If this value is , an average LOD may be used across four fragment shader threads. If this value is , no averaging is performed and each thread accesses its own LOD. The default value is . > Note: > This optional Boolean value is used as a performance optimization hint and it is ignored on some GPUs. Enabling LOD averaging may provide a performance benefit for shaders that sample from explicit per-fragment mipmap levels, or apply per-fragment LOD bias, at the potential cost of reduced texture sample quality. --- Copyright © 2026 Apple Inc.
