Modern Warfare 4 on PC: The Requirements Worth Checking First

A launch checklist, not a benchmark verdict

Call of Duty: Modern Warfare 4’s scheduled PC release date was October 23, 2026. Activision’s support page lists the launch requirements and says that TPM 2.0 and Secure Boot are required to play. It lists an SSD with 115 GB available space at launch, alongside desktop CPU, memory and graphics tiers. Activision also warns that specifications may be updated and that additional space can be needed for required updates.

Those details matter before installing or trying online modes: a PC can have a capable graphics card and still fail a platform-security check. PC Gamer reported the requirement ahead of launch and described firmware-version issues its staff encountered. That report provides useful context, but it is not a population-wide compatibility study. Check Activision’s current support page and your own system configuration rather than assuming one report applies to every machine.

What “recommended” and “target” mean

The official PC feature article describes an intended experience and advertises a target of 90 frames per second at recommended specifications. A vendor target is a stated goal, not an independently measured guarantee across every scene, driver, graphics setting or PC configuration. GamesRadar’s post-release PC review confirms the game was reviewed on PC, but a review experience does not substitute for a controlled hardware benchmark across a representative test suite.

The official requirements are best read as a compatibility and configuration checklist. They do not tell us how the game performs on every supported graphics card, whether a laptop’s mobile GPU is equivalent to a desktop part with a similar name, or whether a particular player will see the announced target. Activision itself notes that laptop configurations can differ from desktop specifications.

A practical order of checks

Before changing firmware, verify the game’s current support documentation, identify your exact motherboard and CPU, and check whether TPM 2.0 and Secure Boot are enabled in the system state the game expects. A BIOS update is not a universal first step: firmware changes are model-specific and can reset settings. Follow the motherboard maker’s instructions if an update is actually needed.

Then check available SSD space and the current version of the requirements page. The listed 115 GB is a launch figure, not a promise that the install will never grow. The source page explicitly allows for additional mandatory update space.

The useful news here is not a claim that one PC will run the game at a particular speed. It is that the launch specification includes security prerequisites that can block access independently of raw GPU performance. Requirements tell players what the publisher currently asks for; only transparent, controlled testing can establish performance under stated conditions.
