As mentioned above, Glimmer appears to be the most noticeable removal affecting Guardians tonight on PS4, Xbox One and PC.
A message from Bungie earlier this week confirmed that they had been looking at current issues affecting the game, although there was no mention of the Glimmer issue.
“Over the last few months, we’ve been gathering feedback associated with game performance,” a message from the Bungie team explains.
“This translates to moments when you may see framerate drops during activities or long load times when accessing a menu. The team has been deep in the code, looking for potential causes of these issues.
“While our goal is to address these at the beginning of the next season, these fixes may be delayed if further issues arise. We’ll be sure to keep you updated as we approach Season of [Redacted]. “
