WaitOnAsyncGraphicsFence(GraphicsFence)

Instructs the GPU to pause processing of the queue until it passes through the GraphicsFence fence.
public void WaitOnAsyncGraphicsFence(GraphicsFence fence)

Parameters

fence

GraphicsFence
The GraphicsFence the GPU waits for. The 
fenceType
of the graphics fence must be GraphicsFenceType.AsyncQueueSynchronisation.

Remarks

This method returns immediately on the CPU. Only GPU processing is affected by the graphics fence.
You can use the 
stage
parameter to wait until the start of the next item's vertex or pixel processing. On some platforms, there's a gap between the end of vertex processing and the start of pixel processing in a draw call. If the last command was a compute shader dispatch, Unity ignores 
stage
.
This method only works on platforms that support fences. Use SystemInfo.supportsGraphicsFence to check if a platform supports fences.
It's possible to create circular dependencies with this function that deadlock the GPU. See GraphicsFence for more information.
Additional Resources: GraphicsFence, CommandBuffer.CreateGraphicsFence.
