So I use the “CPU” workaround and sound channel to 16.
I am a hardcore player. Haven’t freezed yet and played >10 hours.
Even did high push GRs (including a 3P GR130).
So it seems working for me [fingers crossed].
I only had 1 D3 crash in a T16 rift but this is not “freeze lag related”.
Note: if I do encounter freeze lags I will update this message.
