If you've been having VRAM capping issues in Call of Duty Warzone after the latest update, you're not alone. Many players have been experiencing the same issue, which can lead to severe stuttering, FPS drops, and random lag spikes.
The underlying cause could be poor optimization by the developers as many players are experiencing this cap even though their hardware goes far beyond the minimum requirements.
In this guide, we show you a simple tweak that will fix your VRAM capping issues. The fix involves increasing the video memory scale for Warzone, and can be done by going to the Call of Duty Modern Warfare folder located in the Documents folder.

You will find an .ini file called "adv_options.ini" which you need to edit. The exact location of the file should be C:\Users\\Documents\Call of Duty Modern Warfare\players\adv_options.ini.
Open up this file, and you will see "VideoMemoryScale = 0.85". Note that this number can differ case by case, and is the root cause of the bug. 0.85 is a scaling factor for how much of your available VRAM is going to be used when running Warzone.
For instance, let's say you have 8GB VRAM, and if the scaling factor is set to 0.85, then 8GB * 0.85 = 6.8GB. This means that you're capping the VRAM usage at max 6.8GB, and the rest of the capacity is not being used. Increasing the value may fix the issue.
We tried this on our Nvidia GeForce RTX 2060 6GB card, and it seemed to work. The default video memory scaling value was 0.85 for us, and we changed it to 1.0. There does seem to be some nuance though, and we do not recommend going all the way to 1.0 if your starting value is very low. Doing that may in fact add to your stuttering or lag issues. This is typical of weaker hardware.
This tweak has reportedly worked for both AMD and NVIDIA users, and, there's no reason it shouldn't work for Intel as well. If you want more insight regarding your rig's performance during gameplay, download MSI Afterburner for monitoring and optimization. Afterburner and similar optimization utilities and squeeze a surprising amount of extra power from your hardware.
We hope this fixes your VRAM capping issues. If you have any questions or feedback, feel free to use the comments section below.
