Call of Duty: Warzone is harder to play when it stutters a lot. For example, a player’s Reddit post said this: “Warzone keeps stuttering… I can’t get Warzone to run well enough to play.” Big FPS drops typically cause the most significant COD: Warzone stuttering. Many players frequently look for ways to eliminate stuttering that can make Warzone almost unplayable in the worst cases. These are some ways to fix Call of Duty: Warzone stuttering on Windows PCs.
Disable the GeForce Experience In-Game Overlay
Players confirm that turning off the GeForce Experience overlay can remedy Call of Duty: Warzone stuttering. Many players with NVIDIA GPUs will have the GeForce Experience software. This is how you can disable the GeForce Experience in-game overlay:
- Click the NVIDIA system tray icon with the right mouse button and select GeForce Experience.
- Press the Settings button in GeForce.
- Turn off the In-Game Overlay option by clicking that setting’s toggle switch.

Disable Hardware Accelerated GPU Scheduling
Players report that turning off Hardware-accelerated GPU scheduling reduces Warzone stuttering. Although some games can benefit from HAGS, it doesn’t seem that Warzone is one of them. You can turn off the Hardware-accelerated GPU scheduling like this:
- First, click the search box (or its magnifying glass icon) that’s on the Windows taskbar.
- Enter a graphics settings search phrase.
- Select the matching Graphics settings search result in the file finder tool.
- Turn off the Hardware-accelerated GPU scheduling option from there.

Set the Spot Cache to Ultra
Setting the Spot Cache setting to Ultra has fixed Warzone stuttering for some players. Increasing that cache setting enables the game to store a larger number of shadows. This is how you can set the Spot Cache to Ultra:
- Start your Call of Duty game.
- Click the Settings button in Call of Duty.
- Select the Quality tab.
- Then, select Ultra for the Spot Cache option.
- As an optional extra, you can also try selecting a lower general graphics preset for the game. Select Balanced or lower for the Graphic Preset option on the Quality tab.

Adjust the Video Memory Scale Setting
Another confirmed way to fix Warzone stuttering is to turn down the Video Memory Scale setting from 90 to a lower value. That option sets a percentage amount of VRAM for the game. Try adjusting that option as follows.
- Go through steps one to three of the previous resolution to open the Quality tab.
- Scroll down to the Video Memory Scale setting on that tab.
- If your PC has a top-tier graphics card, try setting that Video Memory Scale option to 50 by dragging its slider bar to the left. Or lower that setting’s value to 70 or 80 if your PC’s graphics card is a mid-range or poorer one.

Uninstall Norton 360 Antivirus
Some players have fixed Warzone stuttering by uninstalling the Norton 360 antivirus. Norton 360 has a so-called Game Optimizer feature that causes stuttering. Is that software installed on your PC? If it is, try uninstalling that antivirus package with its removal tool, as instructed on this Norton page.
Alternatively, you can try disabling the Game Optimizer feature in Norton 360, which is enabled by default. Players have also confirmed that disabling that feature fixed their Warzone game stuttering. This Norton help page provides details for how you can access and turn off that setting.
