The lags and stuttering could possibly also be a hardware issue too, depending on what platform you’re playing on. When I first started playing Diablo 4 a little after it first came out, it was on Xbox One, and I had terrible lag around legion events and word bosses, like you do. But when I finally upgraded to the Series X, I noticed that the game greatly improved, and I rarely have any lag problems anymore, so I’m sure an upgrade in specs helped.
