  • Excessive Warzone lag after Windows updates can make the game almost unplayable for some players.

Call of Duty: Warzone is a great game, but many reported Warzone lag after an update. This can be an issue and interfere with your multiplayer sessions.

Some players have reported significantly laggy gameplay arising in Warzone after Windows 11/10 build or patch updates.

That’s not anything new, as such reports date back to 2020 (the game’s release year). Those players noticed significant frame rate drops in Warzone after updating Windows.

In the worst cases, Warzone can be quite unplayable with persistent lagging. The game’s gameplay becomes very choppy and unresponsive because of regular FPS (Frames Per Second) drops.

You might be able to fix Warzone lagging after updates with the potential resolutions outlined below.

Why is Warzone so laggy after an update?

There are multiple reasons for this, and one likely one is that the developers changed something that’s causing the issue. To fix it, it’s advised to disable all background applications that can interfere with the game.

Adjusting your settings is another way that can fix the issue. Of course, don’t forget to keep your drivers up to date in order to prevent further issues.

Are there different types of lag?

Warzone game lag can occur either because of low FPS or high network latency. In the case of the high latency (otherwise lag spikes), Warzone lags primarily because of internet connection issues. Such issues can result in data packet loss when playing multiplayer games.

FPS game lag, however, is a slightly different matter. That lag arises because of low (or dropped) frame rates.

When the FPS rate is generally low or suddenly drops, Warzone’s gameplay becomes a stuttering affair. The resolutions below are generally for fixing FPS lag in Call of Duty: Warzone.
