Reproduction steps:

1. Create a New Project
2. Import "Vegetation Studio Pro" from the Asset Store
3. Install "Entities" and "Post-processing" Packages
4. Open the "Demo" scene
5. Open the Profiler, Enable "Deep Profile", "Profile Editor" and "Record"
6. Enter Play mode
7. Search for "Gfx.WaitForPresent" in the Hierarchy tab of the Profiler
8. Notice that its "self ms" is high (400-500+)

Expected Result: "Instanced Indirect" has similar performance to "Instanced"
Actual Result: "Instanced Indirect" has drastically worse performance than "Instanced"

Reproduced with: 2019.1.4f1, 2018.4.1f1, 2018.3.14f1
