It's the first version both for AMD old and new Grakas, for my PC or VEGAS/ACES-Editing it's really good; the 22.5.1 can go history.
1.
As for my VP20b326, the "Enable Legacy HEVC Decoding" is disabled permanently because it causes more problem than help; Auto-UVD/VCN HW-decoding alone performs this task pretty well.
2.
The Adrenalin Driver will give me 200mHz CPU overclock which leads occasionally driver instability, I reset it to 0; the VRAM Overclock is not really wanted but I like GPU-fans keep running in low RPM.
As my personal perspective the AMD-SAM is disabled for max stability.
3.
If not significantly, I feel the improvement compared to 22.5.1, especially by dispensing with "Legacy HEVC-decoding".
