Capturing Basemark GPU Vulkan medium produces different frame counts (VkTrace vs GAPID)

GAPID 1.1.0
Windows 10 64-bit
Dell XPS 15 w/ 16GB RAM
Intel Integrated and Nvidia 960M

I captured the [BasemarkGPU benchmark](https://www.guru3d.com/files-details/basemark-gpu-benchmark.html) using Vulkan's medium quality test and I get different results.

1. Set EXE to `C:\Program Files\Basemark GPU\binaries\BasemarkGPU_vk.exe`
2. Set working directory to `C:\Program Files\Basemark GPU\binaries`
3. Set arguments to `ResultUpload false TestType ExperienceMedium TextureCompression bc7 AssetPath assets/bsb ProgressBar false Fullscreen false`

When I capture with VkTrace, I get 1536 frames, but when I capture the same benchmark with GAPID I only get 817 frames (according to some messages I see when I run `gapit video`). I know VkTrace identifies frames based on each QueueSubmit, is GAPID identifying frames differently? Or is GAPID not recording every frame?
