When playing D4 in its current stat i cant play youtube on a 2nd monitor as its stuttering and glitchinging, its the same with tring to play netflix/ amazon prime but Spotify is fine. its not the 2nd monitor thats the issue, its that D4 uses all the bandwith and nothing else works in terms of streaming/ watching vids while playing off the same pc. Games like d3 and d2r works fine.
im pc spec is good too, i7 12700k, 32gig ddr5 ram, 3080ti asus, 7000mb read/right ssd
