    hi there,

    if i enable the profiler and enable GPU profiling i get pretty strange results:
    although the camera is set to render in deferred and all objects (well – it is a terrain only) are fully opaque the profiler outputs:
    - RenderDeferred.ForwardObjectsToDepth: 1.645 ms
    - RenderDeferred.GBuffer: 0.028 ms

    - there is no single object using forward rendering in the scene so "RenderDeferred.ForwardObjectsToDepth" should be: 0.0
    - the terrain shader however is pretty heavy so "RenderDeferred.GBuffer: 0.028 ms" does not fit my expectations at all.

    it seems as if profiler and frame debugger are completely broken.
    (tested on win 10, nvidia gforce gtx 970m)

    I tried 5.4.0b23, 5.4.0b25 and 5.4.0f1, all has similar issue. Sometimes, the cost of distant transparent objects is included in the cost of near world space UI. Sometimes, the cost of opaque objects is included in the cost of skybox.
