A day or two ago, the big Winter Update for Battlefield 4 was released to everyone. Some of the major changes include more netcode improvements, the addition of the Squad Obliteration game mode, changes to Quickmatch and more.

The overview of the changes can be seen right now. The full list of changes can be read in this handy (and picture filled) PDF from Battlelog.
Netcode Improvements
Major improvements have been made to the Battlefield 4 network layer. Making the “Netcode” better allows for a more exact multiplayer experience for all participants, and this has been done in various ways. For instance, we’ve done long range network updates by adding a cone to the High Frequency Update (30hz), illustrated in the image below.


Other Netcode improvements we’ve done:
- Network prioritization and filtering has been improved. This now prioritizes health/damage, enemy players and vehicles above all.
- Vehicles now use a larger (front) hemi-sphere shape for collision improvements
- Aiming down sights, or zooming in sitting in a vehicle or on foot, utilizes an even longer range cone for better target acquisition at a distance
- Required bandwidth close to cut in half: Players with less stellar network connections should get a significant improvement, now able to use the High Frequency Update.

Squad Obliteration game mode
We’re adding a new competitive game mode called Squad Obliteration with the Winter Patch. In this mode the fast paced, objective based gameplay of the original Obliteration is scaled down to 5 vs 5 size – balanced and perfected for competitive play. Here are the major differences from the original Obliteration mode:

Squad Obliteration/Obliteration differences
- No vehicles, no parachute spawns
- Secondary base spawns are made available
- First team to destroy two out of three bases wins the round
- Bomb carrier position is only known to the enemy team if spotted

Quickmatch Changes
We want it to be a smooth and intelligent affair to jump straight into a Battlefield 4 match using Quickmatch. That’s why we’ve added new presets and servers to enable you to play it your way. Here’s what we’ve added to Quickmatch.

New player gating: New players can now matchmake into special servers until reaching rank 10, giving them a chance to learn playing Battlefield 4 against other new players.
Ranked Preset support: Players now have the added option to Quickmatch into Ranked servers as an addition to the Official preset available in the past.
Premium Playlists: Three new playlists are added catering to various play styles and including maps from all expansions and base game combined.

If you haven't already downloaded the update, it should be a bit over 1GB on the PC.
