Ever since the Season 6 update, there have been many concerns over the state of the game due to FPS stuttering and new bugs. Luckily, this guide will show you how to fix the low FPS bug in Warzone.

Not only that but there are also many players noting that the game feels blurry despite running on high-end PCs and 4K resolution. We have a solution for all these issues and more. Without further ado, let’s get right into it.

Call of Duty: Warzone | Low FPS Bug Fix

There are a number of things that you can do to potentially solve this annoying FPS issue. First of all, make sure that you are running Warzone on the proper settings according to your PC specifications. Settings like Ray Tracing is extremely taxing and can worsen the performance quite a bit.

The adv_options can be found in Documents.

One of the biggest reasons for frame drops can be due to Call of Duty Warzone not detecting how many cores your system has. To fix this, follow these simple steps

  1. Locate and open Warzone in your PCs “Documents”
  2. Find the “Players” folder and open it
  3. Open the “adv_options.ini” via the notepad
  4. Adjust the “RenderWorkerCount” according to your cores
  5. Set the “VideoMemoryScale” to .75
  6. You will see a noticible improvement in performance

This should hopefully fix your game’s performance but in case it doesn’t, there is another simple solution.

Press the “Esc” Key Twice

If the previous solution did not work for you, then tap the “Esc” key twice and that should do the trick. While this sounds weird, it is mostly because the game thinks you are running it in a minimized window; causing FPS stuttering. Double tapping the key will force the game in fullscreen which will fix the issue.

Reddit user orderabi notes that the ESC method works.

NVIDIA DLSS gives a significant boost in performance.

If you have an NVIDIA graphics card, you can enable their DLSS setting which enhances the performance quite a bit. This technology was introduced to Warzone way back in Season 3 and has been going strong ever since. In layman’s terms, it lowers the game’s resolution and improves FPS. However, the resolution still appears to be crisp and players won’t feel a difference in terms of quality.

How to Enable NVIDIA DLSS for Warzone

  1. Launch Call of Duty Warzone and go to Options
  2. Select the Graphics option
  3. Scroll down until you reach Post-Processing Effects
  4. Set the NVIDIA DLSS according to your preference

You should see a noticeable boost in performance thanks to this technology and it will make your GPU perform better.

Hopefully, Activision resolves this issue as soon as possible in a future update but these are the best solutions you can try right now. Let us know in the comments below if your FPS stopped stuttering or did you see a boost in performance.
