Call of Duty Modern Warfare 4 on PC: requirements, TPM and Secure Boot

Call of Duty: Modern Warfare 4 lists its PC release date on Steam as October 22, 2026. Before you pay or start a 115 GB download, check two things: whether your hardware meets the tiers below, and whether your PC passes the TPM 2.0 and Secure Boot checks, which the game requires. This guide uses the numbers from Activision's own support page.

Official PC requirements

Activision lists three tiers. All of them need DirectX 12, a broadband connection and an SSD with 115 GB of available space at launch.

Minimum:

• OS: Windows 10 64-bit (latest update)
• CPU: AMD Ryzen 5 1400 or Intel Core i5-6600
• RAM: 8 GB
• Graphics: AMD Radeon RX 470, NVIDIA GeForce GTX 970 or GTX 1060, or Intel Arc A580
• Video memory (VRAM): 3 GB

Recommended (Activision describes this as aiming for 90 FPS in multiplayer on High settings):

• OS: Windows 11 64-bit (latest update)
• CPU: AMD Ryzen 5 3600 or Intel Core i7-8700
• RAM: 16 GB
• Graphics: AMD Radeon RX 6600 XT, NVIDIA GeForce RTX 3060 Ti, or Intel Arc B580
• VRAM: 8 GB

Ray tracing tier (Ultra settings with High quality ray tracing at 4K, upscaled):

• OS: Windows 11 64-bit (latest update)
• CPU: AMD Ryzen 7 3700X or Intel Core i7-10700K
• RAM: 32 GB
• Graphics: AMD Radeon RX 9070 XT or NVIDIA GeForce RTX 5070 Ti
• VRAM: 16 GB

Some outlets print slightly different CPU or GPU names for the recommended tier (for example an i7-8700K or an RTX 3060). When sources disagree, trust Activision's page. These are the publisher's targets, not a promise for every PC. We have no verified frame rates for the finished game, so wait for independent testing before you expect a specific number. Our guide to how much RAM you need for gaming and how much VRAM you need explain why the 16 GB and 8 GB lines matter. If you are curious what the top tier is paying for, read ray tracing: when it is worth the cost.

The 115 GB of storage

Activision and the Steam page both ask for 115 GB of available space, on an SSD, at launch. That is the free space the game asks for. Activision notes that mandatory updates may need more, so leave extra room. Use our game download time calculator to estimate how long 115 GB will take on your connection.

Other hard requirements

• AVX: Only Intel and AMD processors that support the AVX instruction set are supported. Very old CPUs may lack it, so check your processor's spec sheet on the maker's site.
• Resizable BAR for Intel Arc: Activision says Resizable BAR is required for Intel Arc graphics cards. If you have an Arc card, read what Resizable BAR is and how to enable it.
• Windows builds: Trial, beta or Insider builds of Windows may not be supported.
• TPM 2.0 and Secure Boot: Both are required, and other security measures may be enforced. Per Activision's support article, without them you are restricted from all online game modes in Modern Warfare 4.

How to check TPM 2.0 and Secure Boot

TPM (Trusted Platform Module) is a security chip, often built into the CPU as Intel PTT or AMD fTPM. Secure Boot is a firmware feature that only lets trusted software load at startup. These steps follow Activision's support article and Microsoft's TPM page.

Check TPM:

1. Press Windows key + R, type tpm.msc and press Enter.
2. If the Status says the TPM is ready for use, check that the specification version is 2.0 (Microsoft's page shows it under TPM Manufacturer Information).
3. If you see "Compatible TPM cannot be found," the TPM may be turned off in the BIOS or not supported.

You can also open Windows Security, then Device security. If there is no Security processor section, the TPM may be disabled.

Check Secure Boot:

1. Press Windows key + R, type msinfo32 and press Enter.
2. Look at BIOS Mode. It should read UEFI, not Legacy.
3. Look at Secure Boot State. It should read On. Off means your PC supports it but it is disabled. Unsupported means you should check your motherboard documentation.

If a check fails

Warning: changing BIOS or UEFI settings carries risk. A wrong change can stop your PC from booting, and Activision is not responsible for changes you make. Follow your motherboard maker's instructions and ask for help if you are unsure. Write down any setting before you change it.

1. In Windows 11, open Settings, System, Recovery, and choose Restart now next to Advanced startup.
2. Choose Troubleshoot, Advanced options, UEFI Firmware Settings.
3. For TPM, look in an Advanced, Security or Trusted Computing section. Enable Intel PTT or Security Device Support on Intel, or AMD CPU fTPM on AMD. Names vary by board.
4. For Secure Boot, look in the Boot section and set it to Enabled. If Secure Boot is greyed out, make sure the boot mode is UEFI and CSM or Legacy is turned off.
5. Save, exit and reboot, then run tpm.msc and msinfo32 again.

Activision also says Secure Boot needs a GPT disk, not MBR. Converting a disk is a bigger job with its own requirements (such as turning off encryption and having no dual boot), so read Activision's and Microsoft's instructions fully before you attempt it, and back up first. Some AMD boards may need a BIOS update. On first launch you may see a UAC prompt for CODBrokerInstaller.exe or enrollaik.exe, which Activision says you must approve.

Launch day checklist

• Run the TPM and Secure Boot checks today, not on launch night.
• Confirm 115 GB or more is free on an SSD, plus some room for updates.
• Update your graphics driver using our guide to updating graphics drivers safely. Activision's page names recommended driver versions for AMD, NVIDIA and Intel, so check it for the current ones.
• Review Windows settings for gaming and close heavy background apps.
• Expect shader work on first launch and read about shader compilation stutter if it feels rough.
