Per Unity Profiler docs (and Unreal Insights), CPU-GPU PARALLELISM means which?
AThe CPU records the next frame while GPU draws current
BBoth run identical code on shared cores in step
CThe GPU prefetches the CPU instructions in advance
DFrame N CPU work waits for frame N GPU work first
Answer & Solution
Correct answer: A. The CPU records the next frame while GPU draws current
Unity Profiler docs: typical engines pipeline CPU (frame N+1 commands) with GPU (frame N drawing). A CPU-bound frame stalls; GPU-bound shows GPU idle gaps.
