UHD630 Metal score 2x lower than OpenCl + hangs at FaceDetection

When using GeekBench5 I have noticed that Metal score is 2 times Lowe than OpenCl, + when it tests FaceDetection algorithm the whole system hangs for 5-7 sec., then releases for 1-2 sec., and hangs again, this hellish loop continues for couple of minutes until FaceDetection test is finished. This does not happen on OpenCl.
As suggested by u/fewtarius I have tried setting different AAPL,ig-platform-id. I've tried the recommended first, and then every other possible for UHD630, same story for every one of them.
Any help or hints would be really appreciated.

• CPU: 8750-H
