Update on this: using the integrated Intel 530 GPU for display, my Timespy score dropped from 3290 to 3287 - within margin of error. With Black Mesa at highest settings, FPS uncapped, the iGPU appears to be saving a whopping 81 MB of VRAM, ~129 MB when alt-tabbed.

All things considered, this seems like a waste of time.
