Short answer: the original DMZ Beta listing requires a 64-bit Windows 10 PC, 8 GB of RAM, a GTX 960 or RX 470-class GPU, DirectX 12, broadband internet and 125 GB of storage. For a more dependable 60-FPS experience in the current Call of Duty PC environment, Activision’s March 11, 2026 guidance points to a Ryzen 5 1600X or Core i7-6700K, 12 GB of RAM, an RX 6600 XT, RTX 3060 or Arc B580, and an SSD with 116 GB free. Competitive refresh rates and 4K require a much faster graphics card and 16 GB of RAM.
DMZ was distributed as a beta mode associated with Modern Warfare II, so its Steam requirements and the current Warzone requirements are useful together: the former establishes the historical DMZ compatibility floor, while the latter reflects the actively maintained PC platform, security checks, drivers and storage behavior.
Which requirements should you use?
Use the Steam DMZ Beta listing to answer whether an older PC is near the game’s original compatibility floor. Use Activision’s current Warzone specification page for buying or upgrading a system, because DMZ shares the Call of Duty PC technology stack and the current launcher environment. Activision notes that specifications can change after launch, so a computer that only meets an old beta listing may still need additional space, updated drivers or newer security features.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →The two documents quote different storage figures. The DMZ Beta listing says 125 GB, while the current Warzone page specifies an SSD with 116 GB available. Treat both as capacity planning numbers rather than a promise that the installation will never grow; mandatory updates can require additional free space.

The DMZ figures come from the Steam DMZ Beta support listing. The current tiers and their stated performance targets come from Activision’s PC System Requirements for Call of Duty: Warzone, updated March 11, 2026.
How to tell whether your PC can run DMZ
1. Check the processor and AVX support
Compare your CPU model with the table, but do not judge by clock speed alone. Activision currently supports Intel and AMD processors with AVX. Very old processors can appear fast enough on paper yet fail the game’s instruction-set requirement. Identify the exact model in Windows under Settings > System > About, then verify that model’s AVX capability in its manufacturer documentation.
2. Check RAM, not just total system memory
Eight gigabytes is the listed floor for both the DMZ Beta and current minimum tier. It leaves little headroom for Windows, voice chat, browsers and recording tools. The current 60-FPS recommendation is 12 GB, and the competitive/Ultra 4K tier is 16 GB. If memory usage reaches the limit, the game may pause while Windows moves data to disk, producing hitching even when the GPU is adequate.
3. Identify the exact GPU and VRAM
Desktop and laptop GPUs with similar names do not necessarily deliver the same performance, and Activision warns that laptop variants may differ or may not be supported. Check the full model in Task Manager’s Performance tab or your graphics driver panel. The current minimum calls for 3 GB of video memory; the recommended tier calls for 8 GB, while the high-refresh/4K tier calls for 12 GB.
4. Confirm an SSD and free capacity
An SSD is explicitly required in the current Warzone specification. Install the game on an internal SSD with at least the stated free space, and leave extra room for updates. A hard disk can cause long loads and inconsistent asset streaming even if the rest of the PC meets the old DMZ Beta numbers.
5. Verify platform security and graphics prerequisites
Current Warzone support requires TPM 2.0 and Secure Boot. In Windows, run tpm.msc to see whether TPM is ready, and use System Information to check the Secure Boot State. If either is disabled, enable the firmware TPM and Secure Boot in UEFI settings, following your motherboard or laptop maker’s instructions. DirectX 12 and broadband internet are also required.
Intel Arc graphics require Resizable BAR. Enable Above 4G Decoding and Resizable BAR in UEFI when your motherboard, CPU and firmware support them, then confirm the feature in Intel’s graphics control software. An Arc card without the required platform configuration may perform poorly or fail the expected compatibility checks.

There is no authoritative per-setting FPS table in the available support material, so avoid promises such as “this toggle adds 20 FPS.” Change one group of settings at a time and measure both average FPS and frame-time consistency in the same location or practice scenario. A stable 60 FPS generally feels better than a higher average interrupted by repeated spikes.

Start with the performance preset
- Launch the game and open the graphics options.
- Apply the recommended or performance preset supplied by the game.
- Confirm that the intended discrete GPU, rather than an integrated graphics adapter, is selected.
- Restart the game if it requests a restart, then record a baseline FPS and frame-time reading.
This establishes a known starting point instead of carrying over settings from a different monitor or GPU.
Choose resolution according to your target
Use the monitor’s native resolution only when the system can sustain the desired frame rate. If FPS or frame pacing is unstable, reduce render resolution first or use the game’s resolution-scaling control. Lowering the number of pixels reduces GPU workload; it is usually more effective than disabling every visibility-related option.
Reduce expensive effects before sacrificing useful texture detail
When the baseline is not stable, lower the most demanding lighting, shadow, volumetric and reflection effects, then test again. Keep textures at a level that fits the GPU’s VRAM when possible: overly aggressive texture reductions can make distant surfaces harder to read without solving a CPU or streaming bottleneck. If VRAM is full, lower texture quality or texture resolution until the allocation warning disappears.

Match the display to the hardware
A 144 Hz or faster monitor does not make a weak system render at that rate. For a 60-FPS target, cap or synchronize output at a rate the PC can hold consistently. For competitive play, use the high-refresh hardware tier as the starting point rather than expecting the recommended 60-FPS configuration to drive 144 Hz at high settings.
Drivers and Windows updates to install first
Activision’s current troubleshooting guidance makes Windows and graphics-driver updates part of the process. The driver versions listed on its requirements page are AMD 25.12.1, NVIDIA desktop 591.59, NVIDIA workstation 582.08, NVIDIA notebook 591.59, and Intel 32.0.101.8531. Driver availability and support can change, so use the vendor package corresponding to your exact GPU and operating system.
- Install pending Windows updates and restart.
- Download the listed driver branch for your GPU category from the GPU manufacturer.
- Choose a clean installation option when the installer offers one, then restart.
- Recheck the selected GPU, resolution and frame-rate cap in the game.
Do not assume that a driver update alone will cure every hitch. It removes a common compatibility variable; CPU limits, memory pressure, storage behavior and network conditions can remain.
Why DMZ can stutter on a PC that meets the requirements
Meeting the minimum is not the same as maintaining a target FPS
The minimum tier describes compatibility, not a guaranteed frame rate or quality level. A GTX 960/RX 470-class card and 8 GB of RAM may launch the game but require reduced resolution and effects. The 60-FPS recommendation is materially stronger and includes 12 GB of RAM and 8 GB of VRAM.
CPU or memory saturation
Stutters that occur during firefights, driving or large-area traversal can indicate a CPU or memory limit. Close browsers, launchers and overlays, check Task Manager while the hitch occurs, and lower CPU-heavy simulation or view-distance options if the game exposes them. If RAM is consistently nearly full, moving from 8 GB toward 12–16 GB is more useful than buying a faster GPU first.

Asset streaming and storage pressure
Install on the SSD, keep substantial free space beyond the required 116 or 125 GB, and allow updates to finish before testing. A nearly full drive or a background disk-heavy task can interrupt asset streaming and create pauses that look like graphics lag.
Thermal or power throttling
If performance starts smoothly and declines after several minutes, monitor CPU and GPU temperatures and clock speeds. Clean blocked vents, use the laptop’s performance power mode when appropriate, and make sure the desktop power connectors are secure. Do not overclock while diagnosing instability; return to default settings first.
Network lag mistaken for low FPS
Rubber-banding, delayed hit registration or players teleporting are network symptoms rather than rendering symptoms. Use a wired connection where practical, stop large downloads and check whether the in-game latency indicator changes when the problem occurs. A faster GPU will not fix a congested connection.
Recommended Free Tools
Crashes, freezes or security errors
Check TPM 2.0, Secure Boot, DirectX 12, AVX support and Resizable BAR for Arc cards before repeatedly reinstalling. Activision’s Warzone Support index links separate procedures for improving lag and in-game performance, installation and setup, crashes and freezes, known issues and PC requirements. Follow the branch that matches the symptom and the current game build.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Hardware targets by use case
Just launching DMZ on an older desktop
Target the DMZ Beta floor only if you accept low settings, possible frame-time variation and limited headroom for updates. The GTX 960/RX 470 class, 8 GB of RAM and a 125 GB installation meet the historical listing, not the experience expected from a modern high-refresh display.
General 1080p play near 60 FPS
Use the current recommended tier as the practical baseline: Ryzen 5 1600X or Core i7-6700K, 12 GB RAM, and an RX 6600 XT, RTX 3060 or Arc B580 with 8 GB of VRAM. Activision describes this tier as 60 FPS in most situations with all options set to high, not as an unvarying result in every scene or future update.
High-refresh competitive play
Plan for the competitive/high-refresh tier rather than the 60-FPS tier. Its Ryzen 5 5600X or Core i7-10700K, 16 GB RAM and RX 9070 XT, RTX 4080/5070-class graphics target substantially higher rendering throughput. Actual FPS still depends on resolution, settings, map activity and later patches.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Ultra 4K
4K multiplies the number of pixels the GPU must render. The same 12 GB-video-memory tier is the appropriate starting point, but you may still need to reduce shadows, reflections or render resolution to keep frame times stable. Treat “Ultra 4K” as a target category, not a guarantee for every update.
A practical upgrade order
- Move the installation to an internal SSD and reserve more free space than the published minimum.
- Update Windows, firmware where necessary and the GPU driver listed for your vendor.
- Increase system RAM from 8 GB toward 12 or 16 GB if usage is near full.
- Upgrade the GPU when video memory or render resolution is the limiting factor.
- Upgrade the CPU and platform when the GPU is underused while frame times remain high, especially at lower resolutions.
- For Intel Arc, confirm Resizable BAR and the required UEFI settings before judging the card’s performance.
This order prevents an expensive graphics upgrade from masking a full memory pool, slow storage or a disabled platform feature.
