Re: Warzone stuttering with 6900 XT

Evening all.. I am the proud new owner of a 6900xt. From a 3080.. why oh why..

I'm facing the same issues and I have tried almost everything.

Tell me this.. are you running windows 10 or 11?
I'm considering trying a windows 10 build to see if that fixes the issue..

Re: Warzone stuttering with 6900 XT

Doesn't matter when you're running the game, if you are facing this issue, it will never disappear until Activision decides to investigate and this is not going to happen. You'll need to wait for the new engine.

Re: Warzone stuttering with 6900 XT

Hi Folks.

I've been trying to reproduce this issue for sometime with Caldera but have so far been unsuccessful. The game seems to run really well for me at very high FPS on two different Ryzen processors, however I do see your posts regarding the Caldera map. Something about that map does seem to cause issues for some users. 

Although I suspect some of you will have already tried these, here are some suggestions I can offer you to try and I will share more information about the configuration I use and play with:


RenderWorkerCount should be set to half your CPU cores. However, for 5800X/5600X I would keep it set to 8/6 respectively. When I was using a 5950X I had it at 8. I found better performance with the 5800X3D when using 8 vs 4.

I recommend keeping the video memory scale at 0.7, especially if you use competitive/low settings often like I do. The game can sometimes use a lot of video memory and so if you use a higher value you will see the game use more which can cause stuttering. Some users have reported lower values like 0.5 help so may want to try that also. 

If you are using two displays, please try disconnecting one of them and just use one display to see if that helps.

Shut down any browsers/Discord etc before running the game to see if that helps.

If you are running any overclocks, I suggest removing those to ensure the system is stable. 

Make sure the OS/Chipset/Display drivers are all up to date and current.

Run a SFC /Scannow command use admin priv in a command prompt Window. 

Try to shut down all background apps. I would suggest trying a selective start-up to run a barebones config to see if that helps :

To reboot in a selective start-up:

  • Press WINDOWS-R on the keyboard to bring up the Run window, enter MSCONFIG and click OK.
  • Under the General tab, click "Normal start up" if it is not selected already.
  • Under the Services tab, put a check on "Hide All Microsoft Services" and then click "Disable All."
  • Under the Start up tab, these will still be disabled in Windows 10 in the Task Manager.
  • Click OK on the MSCONFIG window, and then click Restart when prompted.

I would also suggest disabling hardware acceleration in the app, and have it auto minimize when the game launches. You can set this up via the settings, right click the desktop app > settings. 

Smart Access Memory should always be on when using a Ryzen 5000 series and a RDNA2 GPU, it provides a nice performance improvement. 

The game should always be run in full screen mode from the video menu as  it runs better than when in windowed/borderless mode.

Now run the game and see if things improve.

Here is a video clip of it running on my 5800X3D system: 5800X3D | Call of Duty Warzone Caldera | 6900 XTXH Toxic EE | 1440P Low Settings - YouTube

Here is a video clip of it running on my 5950X system: 5950X | Call of Duty Warzone Caldera | 6900 XTXH Toxic EE | 1440P Low Settings - YouTube


If after trying the above folks continue to experience the issue, please can you provide the following information from your normal day to day configuration for playing Warzone: (example below using my specs)

  • CPU: 5800X3D
  • Motherboard/Bios: Asus Dark Hero 4006 BIOS
  • Memory: 2x16GB 3800Mhz CL14
  • Graphics: 6900 XT Toxic Extreme Edition
  • PSU: 1000W Corsair HX Platinum PSU using two independent power cables to the graphics card
  • Display: 1 Display, LG CX 48£ OLED, connected via HDMI 2.1 cable 
  • OS Build: Windows 10 19044
  • AMD Driver: 22.4.1
  • Chipset Driver:
  • Warzone Settings: Full screen mode, 2560x1440 @ 120HZ. All low settings, except particle High and bullet impacts on
  • Warzone Map/Mode with issue: Caldera only

I would really appreciate it if some folks with this issue could try and capture the issue using ReLive so we can watch it back in video format.

If you can have an overlay running showing a frame time graph at the same time, even better but is not essential as long as the stutters can be seen on screen. If you can provide time stamps in the video of when they happen that would be useful too. 

Lastly, please then submit a bug report using the AMD Bug Report Tool. With all this data gathered I can then file a ticket and ask our engineers to have a look at it to see if we can find a solution. 

Appreciate it.

Re: Warzone stuttering with 6900 XT

Hey Matt, thanks for the response!

Doing what you recommended actually decreased my stuttering to the point that I wasn't noticing it as much as before.
I did all the steps, including changing the settings in the adv_options document (Even though I've tried that several times)
Before my setting were VideoMemoryScale = 0.7 and RendererWorkerCount = 6. I tried with 8 instead of 6 and it seemed better.

But.... The stuttering did increase when I plugged my second monitor back in. I have nothing running in the background. I did the selective start-up as you wrote, so the only thing running was Warzone. How could this be a problem? I usually like having Discord/spotify open on my second monitor when I'm playing. Do you think there's some way to solve this?

  • CPU: 5900x
  • Motherboard: MSI x570 Tomahawk  /  BIOS version 7C84v18
  • Memory: 2x16GB 3600Mhz CL14-14-14-34

  • PSU: 850W Corsair RMx PSU using two independent power cables to the graphics card
  • Display 1: AORUS FI27Q-X 1440p 240hz - Displayport 1.4
  • Display 2: LG 27GL850 1440p 144hz - Displayport 1.4
  • OS Build: Version 10.0.19044 Build 19044
  • AMD GPU Driver: 22.3.1
  • AMD Chipset Driver:
  • Warzone Settings: Full screen mode, 2560x1440 @ 240HZ. All low settings, except particle High and bullet impacts on
  • Warzone Map/Mode with issue: Caldera only

I copied all your in-game settings as well. The stuttering is at its worst when I'm in the warm up lobby and when the match begins. It's especially noticeable in areas like Fields, Mines, Capital and Resort. I'm usually getting above 200 fps in all other locations, but these I'm dipping all the way down to 160.

Would you recommend capping my FPS with software like RTSS or should I just leave it to run at max?

Another question, why is it that my GPU temps goes way up when the match starts and I'm in the plane? My temps on the ground are normally between 60-75, but in the plane (animation) it goes up to 85.
It's also happening in the Vanguard multiplayer when the match ends and we get the character highlights. It goes way up compared to when I'm actually playing.

Again thanks for the input/help.

Re: Warzone stuttering with 6900 XT

Thanks again for your interest in this issue. I tried to do everything you wrote (Some time ago I already tried all the solutions, not in this sequence but I think it is irrelevant for this problem) and this type of issue does not disappear. As I wrote before, the classic stuttering or microstuttering does not occur, it is more of a framelag, as if the game slows down. I have tried all the values ​​in the adv option regarding the VRAM and the processor, but this problem does not go away, as per my expectation. I strongly believe it is an engine issue that has to do with some video cards / systems from AMD, not all.
The problem in question is exactly the same to this one, present in your video:
In my case, this problem is identical from 1:57 minutes of your video to 1:59, it is just as if the view is shaking and, looking at the frametime graph, it's cleary not linear. Still in my situation, the problem  almost always occurs, at intervals of seconds and makes the game horrible to play in any form. I specify that this problem occurs at any type of graphic setting, from the lowest to the highest, so this is why I think that is an engine problem.
Some time ago I also tried to report this problem through Radeon software, however I don't know how much it may have affected, probably nothing.
I am also attaching the video that I sent to Activision 2 months ago (In this video, from the start until 0:30 seconds, you can see my settings used for this video and after, even before the actual start of the game, at 1:30, you can immideatly look at the frametime graph and see what is going to happen just a couple seconds later. It is not easy to see at this quality, because, as I wrote, it is more a framelag. Despite this, you can see the microstutterings at 1:48 until the end of the video. I also tried to look around as fast as possible with the visual with my sensitivity to accentuate this) when I contacted their specialist support. I asked them over and over during our discussion if there was a problem with the 6800 XT. Those who answered me never wrote anything about it, despite my requests, so I wrote that there may be a lack of communication between Activision and AMD with Warzone.

Re: Warzone stuttering with 6900 XT

Just an extra note:

I didn't get to test running the game only using a single monitor and having my audio interface software, Discord and Spotify running in the background. I'll do that tomorrow.

I only tested running my main monitor and then both monitors.

Re: Warzone stuttering with 6900 XT

Discord and Spotify both use hardware acceleration on the GPU. I'd recommend disabling hardware acceleration for both applications to see if that helps.

Try RendeWorkerCount of 12 or 6 instead of 8. 8 is for 5950X/5800X.

I'd let the FPS run at maximum.

The GPU temps go up at the start as the game is very GPU bound at that point and the GPU utilisation goes up to reflect that.
As you get into the main game with all the other players, you will see your GPU utilisation drop a little as it is no longer the limiter of FPS in the system.

Warzone is quite heavy on the CPU with all those players, so that's why GPU utilisation can fluctuate a bit depending on where you are on the map and how many players are nearby.

If your FPS are only dropping to 160 from say 200, that sounds quite good to be honest and what I would expect.

I just want to keep your expectations in check here, the game can be quite demanding on the system with all those players and you can expect some rather wild fluctuations in FPS at various points. My videos show this if you note the minimum and maximum FPS.

Re: Warzone stuttering with 6900 XT

@Tricczyy I'm just noticing that we are both using the same PSU. Corsair RM850.

@Matt_AMD is there any chance that there could be spikes in power draw from the GPU which the PSU cannot handle? I would have thought an 850w psu was well within spec for a 5900x and 6900xt combo.

The attached picture is me running backwards and forwards in the capital at the very bottom of the map near the beach. Every time i turn around and run forward, I get these rather large spikes in frame-times.

@Matt_AMD I cant post my reply with all the videos/informations because the system mark it as spam. I tried multiple times removing youtube/direct video link but seems to not work.
