Playback stutter / Skip frames on Apple TV infuse 7 but not 6

I have infuse 6 pro and now infuse 7 on the same apple TV and the exact same files play differently across versions.
On the latest 6 pro, the file plays perfectly, but on the latest infuse 7 the exact same file is slightly skipping or dropping frames - its only 1080p and speed test on both versions is running 150mbps.

Infuse 7 was a clean manual install, and all settings are exactly the same across versions.

Is infuse 7 using a different player?
