Hackintosh performance (SMBios)

Hey guys, I'm trying to find a proper SMBios for my config on BigSur.

Hardware:

CPU: I9-9900K
RAM: 64GB
GPU: iGPU (no monitor), dGPU RX 6900 XT (XTXH) 16GB
Motherboard: Asus Strix Z390-E Gaming
Ethernet: AQC107
Disks:
- 1x Corsair Force Series MP600 2TB (BigSur system)
- 1x Adata XPG Gammix 1TB (windows 10)
- 1x SSD 512GB (ubuntu)

SMBios iMac Pro 1,1 - stable but few small issues: from time to time mouse freeze for less than 1s (annoying). GeekBench performance is not bad however comparing to SMBios iMac19,1, iMac19,2, iMac20,1 it's lower score. CPU fans are running louder.

SMBios to iMac19,1, iMac19,2, iMac20,1 - GeekBench performance is really good (satisfying, better than iMac19/20 SMBios). CPU fans are silent. However one massive issue - not able to record screen video, unable to play video via preview.

Question: How to fix screen recording and preview video playback on SMBios iMac19/20
