Your Battlefield 4 Beta experience has helped change and shape the full game when it launches. That’s according to DICE. BF4 Changelog
Low frame rate/stuttering
PC players may have experienced trouble in the Beta getting the game running at a good frame rate. Rest assured that we’re using the information we received to optimize the performance for the launch of the game
Stuck on loading screen
We have identified some of the reasons why players, mainly on PC, were getting stuck on the loading screen
High CPU usage during the Beta
CPU usage could sometimes skyrocket for dual, quad and six-core processors. This was a true Beta, and as such all the crash reports that were generated during this period will actually help us make a better game.
Controller layouts (X360/PS3)
We’ve increased the available controller options in Battlefield 4, including the new controller layout and multiple alternatives. If you’re more comfortable with the controls from Battlefield 3, we’ve got you covered. Just by bringing up the options menu, you can choose the “Legacy” layout, which is similar to that in Battlefield 3.
Empty server listings (X360/PS3)
While in the Server Browser you may have seen lists of empty servers. By changing the filter options, you’ll be able to find populated servers that you can join. You can also use the “Quick Match” function to quickly get into the action.
The elevator catapult (All platforms)
Elevators were never designed to act as a catapult or teleporter. The bug where the elevator button would catapult you up into the air is fixed for the final game.
-Fixed how the player only receives a single local damage sound effect if he or she was the victim of a quick, clean kill.
-Reduced the fire rate of the AK12 in burst from 1000rpm to 750rpm
-Tweaked the compensator and muzzle brake so they’re properly less accurate in sustained automatic fire.
-Reduced and rebalanced full auto accuracy based on rate of fire for all automatic weapons to balance low ROF weapons.
-Increased the default throw distance of the portable ammo and med packs
-Portable ammo packs now reload 2 magazines of bullets instantly and up a total of 4 magazines per pack over time. The player must stay on top of the ammo pack in order to benefit from all of the ammo reloading. Grenades, RPG’s, and other explosive launchers do not benefit from the instant reload function of the Ammo Pack.
-Increased the muzzle flash of the 25mm and 40mm launchers
-Fixed an issue where the knife stab didn’t align with the kill event.
-The revive time has been increased from 7s to 10s.
-Fixed some descriptions of weapons for vehicles that incorrectly described the function of the weapon.
-Increased the damage of the Stinger and IGLA to 3 hits to kill attack choppers (was 25%, now 35%).
-Increased the speed of all TOW guided missiles to 75m/s from 50m/s so they can catch-up to fast vehicles like the Quad bike.
-Increased the sustained fire accuracy of the Coaxial LMG on armored vehicles
-Reduced the damage the 40mm and 25mm infantry weapons do to armored vehicles to highlight their anti-infantry role.
-Reduced the damage main gun on the IFVs against other armor to highlight their primarily anti-infantry role.
-Fixed an issue where the tank main gun did not correctly hit the center of the crosshair at all times.
-Multiple options are now available for controlling how your vehicles steer with a joystick on all platforms, as well as improved the responsiveness of steering while accelerating.
Locking Weapon Changes
-RPG7 and SMAW can no longer lock on to Laser Designated Targets
-Fixed some projectiles not warning vehicles when they were fired on a Laser Designated target. Reduced the lock on distance for RPGs, SMAW, and MBT LAW missiles to 350m from 500m
-All Laser Designated missiles now do a maximum of 90% damage to Attack and Scout helicopters (down from 100%)
-The kill string in the score log now appears sooner, making the UI more responsive to a kill event.
-The aim assist on X360/PS3 has been tweaked to be more consistent at all ranges
PC Specific Changes
-Fixed a string in On Foot PC key bindings that should have read “CROUCH (TOGGLE) / PRONE (HOLD)”.
-Removed an unused “Underslung” key binding on PC, the “Select Gadget 1″ key binding now controls both of these actions as expected.
