It all began back at the end of Season of the Worthy: I had started playing when Shadowkeep launched and had really good performance (almost smooth 60fps) for half a year. Then, all went to hell in Season of Arrivals, where basically the game still ran fine, but then decided to have these massive drops to the low tens out of nowhere. Even with lower settings, frames still dropped. Come Beyond Light, the game felt streamlined, yes, but occasionally frames still dropped and now I'm back to where it all began: as soon as I keep playing, frames drop massively for no reason. How can I run Doom Eternal at 60fps and Cyberpunk 2077 at above 30fps, while this game from 2017 decided to ruin its performance out of the blue?
