If you try to boot up the latest Call of Duty on your Xbox One and PlayStation 4, you’ll need to download a new update to continue.

Developer Sledgehammer Games rolled out the first patch for its futuristic military shooter, and it’s now available for the Xbox One and PlayStation 4. This update introduces a huge list of changes — although fans are most interested in seeing if this fixes the lag that some players are experiencing.

The developer pushed out the PC update earlier this week.

You can get more information about the update from the Call of Duty website, but here is a list of big changes and improvements you’ll get in the patch:

  • Adjustment to the in-game chat name-notifications placement.
  • Fixed Prestige reset issues, including emblems and challenges.
  • Fixed marksman and camo challenges to not reset when you Prestige.
  • Connectivity optimizations for game servers.
  • Fixed issues with Ping Bar not updating correctly.
  • Fixed stats not accumulating toward leaderboards after Prestiging.
  • Adjustment to challenges to unlock camos for weapons.
  • Fixed round-based game modes, affecting Win/Loss ratios.
  • Implemented ability to unlock e-sports rule options in Private Match.
  • Fixed weapon reloads counting as speed reloads in certain circumstances.
  • Added description to reload informing that you can double-tap to speed reload.
  • Fixed DoubleXP splash, so it doesn’t show up in Private Match, Combat Readiness Program, or Exo Survival mode.
  • Showing 4x or 2x based on whether a loot DoubleXP item exists.
  • Add DoubleXP icon to medal splashes when DoubleXP is active.
  • Fixed rare save game issue affecting playthrough progression.
  • KC score limit increased to 85 per match.

We’ll keep an eye on this update and see if it shows any big improvements or has any issues.
