@rasher123 for me that does not work was trying a lot of things but its still worst browser for me after recent updates for example i cant see any videos they are lagging/freezing or loading after minute i guess they dont care about amd or ryzen users so theres no other option then change a browser because at other i dont have any problems ( if we not include 4320p60 8k in 60hz ... but still it uses less memory and do not freeze like random video in hd(720p) at opera when there is just forum open nothing else then that... maybe il find a way to move all stuff from opera to chrome if not it will be sad...

My Spec:
B450 TOMAHAWK MAX
AMD Ryzen 5 3600x (4.4Ghz)
32GB Ram ( DDR4 3200 - best compatible RAM with this procesor) 16x2 in two correct sockets ( 1 slot and 3 slot)
AMD Radeon RX 6800 16GB

if got same problem now but for me its even if i have jus one video opened no matter where ( twitch/youtube/facebook) everything is lagging like hell had to switch browser for chrome and there i dont have any problems even with 8k videos
