After clean reinstall of "final" High Sierra
My Vega 64 works much better...
I mean...
Heaven Benchmark (at least) done (without freeze), all others benchmarks OK,
I can do a lot more without that system freeze, but it's steel not perfect because
when I use Chrome or Opera (after while for example on YouTube) I have same problems like before
BIG Freeze and Session restart or UltraBig Freeze and I have to restart PC....
On the same time, I have a little nice performance improvement with my CPU 7900X
Lilu kext - used 1.1.7
Whatevergreen 1.0.4
BTW: About Internet browser- in Safari everything works perfect,
but some people like me "need more than 2" browsers on the same time
so I hope it will be fixed soon
