I added the Immerse audio pack trial and it has resolved the stuttering issue roughly 95% of the time - but I now have the "underwater" audio, which is bearable but not ideal.

This feels like a really shady business practice by SE. They've created a problem and are trying to sell the subpar solution, trying to shift the blame onto the players hardware.

Over 75 pages and 700+ posts, not to mention other websites where the issue is being voiced. I think people need to start reaching out to game news sites/streamers to get this issue highlighted.
