### Remarks

Same as [ComputeBufferMode.Dynamic](/engine/6000.6/script-reference/unityengine/computebuffermode/dynamic.md) except Unity does not perform any CPU-GPU synchronization; if the user modifies an area of the buffer where the GPU is currently reading from, the results are undefined. For example, this mode together with [GraphicsFence](/engine/6000.6/script-reference/unityengine/rendering/graphicsfence.md) can be used to implement circular buffers.
