I agree with you. right now i am using 2.9d. after this version all of them crashes. i am sure developer will figure out soon.
Same problem on both my rigs with 9 AMD cards each.
I've upped my virtual space to 80 GB, turned down MI to 8 starting from 12, tried altinit, gser 1-6 and nothing works.
Sometimes it would sporadically go through, but after I restart ( cause i like to do it weekly), it keeps crashing and I have to just keep trying again and again before it works again.
Except this time, after 4 restarts, and multiple (10+), i gave up and went back to claymore on 1 of my rigs cause I'm remote and don't have 2.9 installed.
