Modern Warfare 4 Beta PC Requirements and Patch Notes

Modern Warfare 4 Beta PC requirements have been officially confirmed by Infinity Ward, alongside the full patch notes for Weekend 1. The publisher has detailed the minimum and recommended specs PC players need, along with a mandatory security requirement tied to RICOCHET Anti-Cheat.

The patch notes also confirm the maps, modes, weapons, and progression system available at launch. Early Access for Call of Duty: Modern Warfare 4 begins on August 21, 2026, with the Open Beta following on August 28. Here is everything confirmed so far.

Modern Warfare 4 Beta PC Requirements: Minimum and Recommended Specs

Infinity Ward has kept the Modern Warfare 4 Beta PC requirements manageable compared to other recent AAA shooters. The minimum specs run on hardware as old as an AMD Ryzen 5 1600 or Intel Core i5-8400, while the recommended tier targets a smoother 1080p to 1440p experience.

Activision also recommends specific driver versions for the beta: NVIDIA 610.47, AMD 26.7.1, and Intel 32.0.101.8861. The game needs 50 GB of free SSD space and a broadband internet connection. It is available for download through Battle.net and Steam.

TPM 2.0 and Secure Boot Requirement

PC players must enable TPM 2.0 and Secure Boot to access online modes in the Modern Warfare 4 Beta. These are Windows security features that form the foundation for RICOCHET Anti-Cheat, and Activision has confirmed that players who do not meet this requirement will be restricted from online play. Activision recommends running the Call of Duty Secure Attestation Wizard before launch to verify the PC meets the required security standards.

Mobility Course 

MW4’s grounded movement prioritizes fluidity and freedom. We made a Mobility Course for players to learn, experiment, and master the system. Spend a few minutes learning the basics, or a few hours challenging yourself for the best time possible. Either way, you’ll feel the difference the next time you load into Multiplayer.

Weapons

Weekend One gives you access to 14 weapons that showcase MW4’s variety, personality, and balance. The team has worked hard on handling, presentation, and gameplay with the goal of delivering the best first-person gunplay we’ve ever made. Gunsmith lets you push the boundaries of each weapon’s capabilities, and Apex Attachments let you take those builds even further.

With weapon progression, we cut down redundant attachment grinding. Attachments you’ve already earned can be used on other guns as well, giving you more customization options faster as your arsenal expands.

We’ve spent countless hours playtesting these weapons, honing their designs, and dialing in the tuning, and we’re excited to finally get them into the hands of our players.

Here are some Apex Attachments the team suggests you try out in Beta:

• The Han 86 transforms into the Han X20 Skybreaker. This advanced weapons system mounts to the top of the receiver and allows the platform to deploy 20mm airburst rounds which detonate at a specified distance.
• The X-58 Nyx becomes the X-58 Void. Complete with a brass catcher and an extended, wrapped suppressor, the X-58 Void is the ultimate stealth platform – hiding enemy death markers and obfuscating the directional hit indicators of its targets.

Killstreaks 

In MW4’s Killstreak system, a kill still counts as a point no matter what mode you’re in. However, we want to make sure we reward objective players as well. With our new Smart Streak layer, taking a Domination Flag, holding a Hardpoint, or planting the Data Spike all contribute to your Killstreak Meter. 

Progression & Rewards 

Every Multiplayer match earns XP toward your Player Level, unlocking additional gameplay content as you progress through Beta.

During Weekend One, the level cap is Level 20. When the Open Beta begins in Weekend Two, the cap increases to Level 30, with additional Weapons, Equipment, Perks, Killstreaks, and rewards.

Here’s what you can earn throughout both weekends:

PC Experience 

As a reminder, PC players must have TPM 2.0 and Secure Boot enabled to play the Modern Warfare 4 Beta online.

These Windows security features provide a trusted foundation for RICOCHET Anti-Cheat and make system-level tampering more difficult, helping protect the integrity of the Beta from Day One.

If you already have TPM 2.0 and Secure Boot enabled, you’re ready to go. If either feature is disabled, you won’t be able to play the Beta online.

Players can also run the Call of Duty Secure Attestation Wizard before jumping in to verify their PC meets the required security standards.

Progression and Rewards

Every multiplayer match earns XP toward Player Level, unlocking additional content as players progress. The level cap for Weekend 1 is set at Level 20. When Weekend 2 of the Open Beta arrives, the cap rises to Level 30, along with additional weapons, equipment, perks, and killstreaks.

Known Issues in the Beta

Infinity Ward has also listed several live issues players may encounter during the beta, including incorrect display of 4x optics while aiming down sights, the loadout screen occasionally remaining visible after a match starts, and animation timing discrepancies when observing other players transition from slide to sprint. Frame rate drops with Quick Draw attachments and hitching linked to recording software such as NVIDIA ShadowPlay have also been reported.

Modern Warfare 4 Beta Release Dates

Early Access for Call of Duty: Modern Warfare 4 starts on August 21, 2026, for players who pre-purchased the game. The Open Beta then opens to all players on August 28, 2026.
