Terrible performance in Forza games -UWP

[MinusMyX]

Ryzen 2600x
32Gb RAM
Radeon RX580 8Gb
Windows 10 x64
All drivers up to date.

My Action! recordings in Forza Horizon 3 and 4, and Forza Motorsport 7 are barely watchable as they come out at around 20 fps or less.
My settings are AMD-AMF, 60 fps, MP4, clearly with hardware acceleration enabled.
Are you working on a fix for this?
Thank you.
