Compute tunneling can considerably lower the latency of high-priority compute work. Enabling it is beneficial in cases where high-priority work is dispatched while the GPU is already busy with other work (e.g. rendering on GFX). This is the case in VR compositors that dispatch latency-sensitive compositing work to ACE while GFX is busy rendering the next frame.
