ObsVCE logic error
Release D3D/DXGI interface[1]. MFT: wait for and send only 1 frame packet.[2]

[1] Atleast no more debug output about live objects.
[2] Apparently it doesn't work like I thought OBS does it, so should fix random blockiness/frame corruption.
MFT: Set key interval and use CBR from app config, duh.
