Call of Duty expert WhosImmortal has provided what he believes is the best loadout for Resurgence on the new Vondel map in Warzone 2 Season 4. The loadout includes the M4 and the Lachmann sub, with the M4 built for low recoil and a great TTK, and the Lachmann Sub covering close-ranged engagements. The 60 Round Mag is now mandatory due to the health increase across Warzone 2. The Lachmann Sub loadout is super easy to use and worth a try.
A Reddit user has discovered a simple trick to boost FPS in Warzone 2 on PC by changing the Game Voice Channel to "Friends Only" in the audio settings. This removes proximity chat but significantly improves gameplay responsiveness. The trick only works on Steam and not Battle.net. The reason for the FPS boost is unclear, but it may be due to the amount of audio processing in the background.
Players have discovered that changing the Game Voice Channel setting from All to Friends Only in Warzone 2 and Modern Warfare 2 Season 3 can significantly boost FPS. Many fans have reported a decrease in FPS following the Season 3 update, but altering the Voice Chat setting could fix the issue immediately. The low FPS issue is more prevalent for those playing on Al Mazrah in Warzone 2, due to the number of people in the game who have Voice Chat enabled. However, changing Voice Chat from All Lobby to Friends or even Party Only will mean that you no longer get access to Proximity Chat in Warzone 2.
