Short answer: the original DMZ Beta PC listing requires a 64-bit Windows 10 system, 8 GB of RAM, a GTX 960 or RX 470-class graphics card, DirectX 12, broadband internet and 125 GB of storage. For a more current target in the shared Call of Duty PC environment, Activision’s March 11, 2026 guidance points to an RTX 3060 or RX 6600 XT-class GPU, 12 GB of RAM and an SSD with 116 GB available for 60 frames per second in most situations with High options. Competitive high-refresh and Ultra 4K play requires a much faster platform.
Use the DMZ listing to judge basic compatibility, then use Activision’s current Warzone tiers to plan performance, upgrades and troubleshooting. Settings should be tuned by measuring frame rate and frame-time consistency rather than expecting a fixed gain from one switch.

Which PC requirements apply to DMZ?
DMZ was published as a Beta mode in the Call of Duty PC ecosystem, so two requirement sets are useful. The Steam technical listing gives the identifiable DMZ floor and recommended hardware. Activision’s current Warzone requirements, updated March 11, 2026, are the better performance reference for the maintained PC environment that shares the same technology and launcher components.
What’s actually slowing this PC down?

The Steam page lists Windows 10 64-bit, an Intel Core i3-6100 or Core i5-2500K (or AMD Ryzen 3 1200), 8 GB of RAM, an NVIDIA GTX 960 or AMD RX 470, DirectX 12, broadband internet and 125 GB of storage as the DMZ Beta minimum. Its recommended tier raises the processor to an Intel Core i5-6600K or Core i7-4770 (or AMD Ryzen 5 1400) and the graphics card to a GTX 1060, RX 580 or Intel Arc A770, while keeping 8 GB of RAM, DirectX 12, broadband and 125 GB of storage. The listing identifies Windows 10/11 for that recommended tier.

Activision cautions that its specifications are valid for product launch and may change. Its current page also makes TPM 2.0 and Secure Boot mandatory for Warzone, requires an SSD, and supports only Intel or AMD processors with AVX at the time of publication. Those platform checks can prevent launch even when the CPU and GPU appear fast enough.

Can your PC run DMZ?
Check the following in order. A “yes” on the graphics card alone does not guarantee a successful launch.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- 64-bit Windows: the minimum DMZ listing names Windows 10 64-bit. The current recommended Warzone tier names Windows 11.
- AVX-capable CPU: Activision says only Intel and AMD processors with AVX are supported at the time of publication. Very old processors can fail this requirement despite meeting a nominal model comparison.
- DirectX 12: both the DMZ listing and current Activision guidance require DirectX 12.
- TPM 2.0 and Secure Boot: Activision states, “TPM 2.0 and Secure Boot are required to play Call of Duty: Warzone.” Enable both in UEFI firmware when your system supports them.
- Graphics memory and performance: the current minimum specifies 3 GB of video memory; the 60-FPS High tier specifies 8 GB. Laptop GPUs with the same name as desktop cards can have different capabilities and may not be supported.
- Intel Arc configuration: Intel Arc cards require Resizable BAR. Confirm that the motherboard firmware, CPU platform and operating-system settings expose it before choosing an Arc card for this game.
- Broadband connection: an internet connection is required. Connection quality affects online latency separately from rendering performance.
- Free SSD space: the current requirement is an SSD with 116 GB available, while the Steam DMZ listing asks for 125 GB. Keep additional headroom because mandatory updates can increase the space needed.
A practical compatibility check
- Open Windows System Information and confirm a 64-bit installation, your processor model and whether the machine is using UEFI firmware.
- In UEFI setup, verify TPM 2.0 (often shown as Intel Platform Trust Technology or AMD firmware TPM) and Secure Boot are enabled. If you change firmware mode, check that Windows still boots before launching the game.
- Check the GPU model and its dedicated video memory in Windows Task Manager or your graphics driver panel. For a laptop, verify the exact mobile GPU rather than relying on the desktop name printed in a specification sheet.
- Confirm that the game library is installed on an SSD and that at least the required free space remains after the installation. Leave room for updates instead of filling the drive to its limit.
Why an SSD matters
SSD storage is an explicit requirement in Activision’s current Warzone guidance, not merely an optional loading-time upgrade. The current figure is 116 GB available on an SSD; the separate Steam DMZ Beta listing gives 125 GB of storage. These numbers are not contradictory promises about permanent installed size: they come from different listings and can change as the shared client receives mandatory updates.
Use an internal SSD with enough free capacity for the client and future patches. The published requirements do not establish a specific SATA or NVMe speed, so do not treat a particular interface as a guaranteed frame-rate improvement. The relevant requirement is solid-state storage and sufficient free space. If the game is on a hard disk, moving it to an SSD is the first storage change to make before chasing graphics settings.

Graphics settings that improve DMZ performance
Start with a stable baseline, then change one group of settings at a time. Activision does not publish an authoritative per-setting FPS table, so any claim that one toggle always adds a fixed number of frames would be misleading. Judge each change by average FPS and frame-time consistency during an actual match or repeatable route.
- Update Windows and the graphics driver. Activision’s current page lists vendor-specific driver versions: AMD 25.12.1, NVIDIA desktop 591.59, NVIDIA workstation 582.08, NVIDIA notebook 591.59 and Intel 32.0.101.8531. Use the package appropriate to your GPU and notebook or desktop category, then restart Windows.
- Select the correct GPU. On systems with integrated and discrete graphics, confirm the game is assigned to the high-performance adapter in Windows Graphics settings or the vendor control panel. A monitor cable connected to the motherboard can also cause confusion on a desktop.
- Apply the game’s recommended or performance preset. Use it as a controlled starting point rather than mixing settings from an old guide. Restart or allow shader preparation to complete if the client requests it.
- Choose resolution according to the frame-rate target. Keep the monitor’s native resolution when the system can sustain the target. If FPS or frame pacing is unstable, lower render resolution first or reduce the most expensive visual-effects controls exposed by your build.
- Protect visibility-critical textures. After reducing render resolution or costly effects, lower texture quality only as needed to fit available video memory. Blurring textures can make distant objects and loot harder to read without solving a CPU or network bottleneck.
- Measure after every change. Record the same scene or match segment, watching for sudden frame-time spikes as well as the headline FPS number. If a setting lowers the average but makes pacing steadier, it may produce a better experience than a higher, erratic average.
Choosing a sensible target
- Hardware near the DMZ minimum: prioritize a playable, consistent frame rate over native-resolution image quality. Begin with the performance preset and be prepared to lower render resolution and expensive effects.
- RTX 3060/RX 6600 XT-class hardware with 12 GB of RAM: use Activision’s recommended 60-FPS High tier as the planning target. Native resolution is appropriate only when frame pacing remains stable in real matches.
- High-refresh or Ultra 4K systems: treat the Ryzen 5 5600X/Core i7-10700K, 16 GB RAM and RX 9070 XT/RTX 4080/5070 tier as a substantially higher target. A minimum-spec PC cannot be tuned into this class by changing a few options.
Diagnosing stutter when your hardware meets the requirements
Low FPS or uneven frame times
Meeting a minimum requirement means the game can be compatible; it does not promise a fixed frame rate. An 8 GB system may have little memory left for Windows and background applications, while a processor near the minimum can limit frame delivery even when the GPU is underused. Close unnecessary applications, check memory use, and compare GPU utilization with CPU utilization during the same scene. If the GPU is not busy while frame times spike, reducing resolution will not address the limiting component.
Recommended Free Tools
Stalls during loading or asset streaming
Confirm the installation is on an SSD and that the drive has substantial free space beyond the stated requirement. A nearly full drive or an update that cannot expand cleanly can produce installation and loading problems. The published figures are 116 GB available for the current Warzone client and 125 GB in the Steam DMZ listing; plan for growth rather than treating either number as a permanent ceiling.
Launch blocks or security errors
Recheck TPM 2.0, Secure Boot, UEFI mode and AVX support. Intel Arc users must also verify Resizable BAR. These are platform requirements, so lowering graphics quality cannot bypass them.
Driver crashes or freezes
Install the driver version Activision lists for your vendor, keep Windows current, and reboot before retesting. If the problem persists, use Activision’s support hub, which provides separate paths for improving lag and in-game performance, installation and setup, crashes and freezes, and known issues: Call of Duty: Warzone Support.

Network lag mistaken for graphics stutter
Broadband internet is required, but a connection problem and a rendering problem have different symptoms. Network delay can make players teleport or actions arrive late while local FPS remains steady. Rendering stutter appears as uneven frame delivery even when the connection is normal. Check the game’s network indicators and frame-time behavior separately before buying hardware.

- Move the game to an SSD if it is currently on a hard disk, and retain free capacity for updates.
- Increase system memory when moving from the 8 GB floor toward the 12 GB recommended tier or 16 GB high-refresh tier. Match the modules and motherboard specification rather than mixing incompatible kits.
- Upgrade the GPU toward the RTX 3060 or RX 6600 XT class for the current 60-FPS High target. Check video memory, power supply capacity and case clearance, especially in compact systems.
- Address CPU limits when GPU utilization is low and frame times remain high after sensible settings changes. The recommended and high-refresh tiers use newer Ryzen 5/Core i7 generations than the DMZ minimum.
- Verify platform features before replacing a graphics card: TPM 2.0, Secure Boot, AVX support and, for Intel Arc, Resizable BAR can determine whether the system launches at all.
What the requirements do—and do not—promise
The DMZ Beta minimum is a compatibility floor, not a guarantee of smooth play at a particular resolution. Activision’s current recommended tier is explicitly framed as 60 FPS in most situations with all options set to High, which is a more useful target for a new build or major upgrade. The competitive/high-refresh and Ultra 4K tier is a separate class requiring 16 GB of RAM, 12 GB of video memory and much faster CPUs and GPUs.
Because Activision can update requirements and the shared client receives mandatory patches, recheck the current support page when a major update changes behavior. Keep the operating system, drivers, firmware security settings and storage capacity aligned with the current tier you are targeting.
Bottom line
For basic DMZ compatibility, plan around the Steam Beta floor of a GTX 960/RX 470-class GPU, 8 GB of RAM, DirectX 12 and 125 GB of storage. For a dependable modern target, use Activision’s current 60-FPS guidance: an RTX 3060/RX 6600 XT-class card, 12 GB of RAM, an SSD with 116 GB available, Windows 11 and the required TPM 2.0 and Secure Boot settings. Start with the recommended preset, lower render resolution or expensive effects when frame pacing is unstable, and verify drivers and platform requirements before assuming a graphics toggle is the problem.
