Activision requires TPM 2.0 and Secure Boot for Warzone PC play
Warzone’s PC gate now includes TPM 2.0 and Secure Boot, so older rigs and unprepared BIOS setups could be locked out before matchmaking starts.
Activision turned Warzone’s PC spec page into a security checkpoint. The March 11, 2026 requirements sheet says TPM 2.0 and Secure Boot are required to play, which means the issue is no longer just frame rates or GPU headroom. Players on older hardware, stale BIOS settings, or unprepared Windows installs now have to clear a system-level eligibility test before they can even queue.
The page also shows how far the bar has moved beyond a routine spec refresh. Warzone’s listed PC setup is built around DirectX 12, a broadband connection, and Intel or AMD processors with AVX support. It keeps an SSD requirement and lists 116 GB available at launch for the listed specs, while separating the experience into minimum, recommended, and competitive or ultra-4K tiers. Intel Arc GPUs also need Resizable Bar, reinforcing that the game is now tied to more than raw graphics power.
Activision had already signaled the shift months earlier. Its support article says TPM 2.0 and Secure Boot were added to Call of Duty with Season 05 in August 2025, and that they are required for Warzone and Black Ops 7 but not for other currently available Call of Duty titles. In Season 05 messaging, Activision said it was not enforcing either setting yet, but that both would be foundational for stronger protections later. By September 2025, TeamRICOCHET said the Black Ops 7 PC beta required both features, and by December 2025 Activision said Warzone did too.
The anti-cheat case is now built into the hardware layer. Activision said RICOCHET Anti-Cheat uses Remote Attestation with Microsoft to verify critical PC security settings as part of TPM 2.0 implementation, tying enforcement to trusted firmware and operating-system checks instead of relying only on in-game detection. The company has also said it shut down more than 50 cheat providers and disrupted nearly 300 reseller operations over the last year, framing the new PC baseline as part of a wider crackdown.
For players, the practical impact is immediate: a PC that runs Warzone well may still be blocked if TPM 2.0 or Secure Boot is off, missing, or misconfigured. The March 11 page makes that plain. In Warzone now, getting into the match starts with proving the machine itself belongs on the field.
