MW4 PC Requirements: 115GB SSD, TPM 2.0, Secure Boot

Call of Duty: Modern Warfare 4 asks for 115 GB of free space on an SSD on PC, and it will not run at all unless TPM 2.0 and Secure Boot are switched on. Those two security checks trip up more players than the GPU requirement does. Here is the full spec list from Activision's support page and how to get your PC ready.

Quick summary

• Storage: 115 GB on an SSD for every tier. Hard drives are not supported, and mandatory updates may need more.
• Minimum: Ryzen 5 1400 or Core i5-6600, 8 GB RAM, GTX 970/1060, RX 470 or Arc A580.
• Recommended (90 FPS, High, multiplayer): Ryzen 5 3600 or Core i7-8700K, 16 GB RAM, RTX 3060 Ti, RX 6600 XT or Arc B580.
• TPM 2.0 and Secure Boot are mandatory. Intel Arc cards also need Resizable BAR.

What are the Modern Warfare 4 PC system requirements?

The listing is for desktop PCs. Activision notes that some laptops use matching graphics cards but can be different models and may not be supported. Only Intel and AMD processors with the AVX instruction set work, and DirectX 12 plus a broadband connection are required.

Why do I need TPM 2.0 and Secure Boot?

Activision says both are a condition of playing, and that further security measures may be enforced. The company ties them to RICOCHET Anti-Cheat, arguing they give it a trusted base and make tampering harder, which matters most for Warzone. In the beta, PCs without them could not play online. Many modern PCs have both features but with one disabled in the BIOS or UEFI, so check before you buy or download.

How do I check TPM 2.0 and Secure Boot on Windows?

• Press Win+R, type tpm.msc and look for "Specification Version: 2.0".
• Press Win+R, type msinfo32 and check that "Secure Boot State" says On.
• If either is off, enter your motherboard firmware and enable fTPM/PTT (often called Security Device Support) and Secure Boot. Menu names vary by brand.

Disk partition style can also block Secure Boot on older installs, so back up before changing anything.

How big is Modern Warfare 4 on PC, and is it the same on consoles?

The 115 GB figure is the free space Activision asks for at launch. It is more than the beta's listed numbers, so redo the math if you were planning around that. Console sizes depend on which packs you install; reports put PS5 at roughly 117 GB without Warzone and about 159 GB with it, and the Switch 2 version at about 90 GB. Treat those console numbers as third-party figures rather than an Activision statement.

Will my older PC run it?

The minimum tier is generous: a GTX 1060 and a Core i5-6600 are both several years old. The catch is the SSD and the security checks, not raw power. For smooth 90 FPS multiplayer on High, aim for the recommended tier and 16 GB of RAM. The ray-tracing tier is aimed at upscaled 4K, so expect to need a recent RTX 50 or RX 9000 card for it. If you are weighing a GPU upgrade, note that prices have been rising; see our Radeon price increase report.
