Call of Duty Modern Warfare 4 Beta size: What Is Confirmed
The current official beta information confirms that an SSD is required, but it does not publish a final download size in gigabytes. Treat any unofficial number as an estimate until the platform storefront displays the actual package size.
The beta is distributed as a separate installation rather than automatically arriving with the standard Call of Duty install. This makes it easier to launch directly, but it also means you must reserve storage for a new download instead of assuming an existing installation already includes the required files.
Official Modern Warfare 4 Beta specifications and preload details provide the current requirements. The listed storage guidance is SSD required, with no numeric capacity stated in the available specifications.
| Storage question | Confirmed guidance |
|---|---|
| Published beta size | No official GB figure currently listed |
| Required drive | SSD |
| Installation type | Separate beta installation |
| Automatic download | Not included with a normal Call of Duty update |
| Best practice | Keep additional free SSD space for updates and temporary files |
Official figure
The available specifications confirm SSD storage but do not give a final numeric download size.
Separate package
Find and install the beta independently through your platform storefront or launcher.
Update buffer
Leave spare space beyond the initial package for patches, shader data, and installation overhead.
Do not rely on a social post or storefront screenshot as the final Call of Duty Modern Warfare 4 Beta size. Package sizes can change before preload, during the beta, or between platforms.
PC Requirements and Storage Planning
The beta PC specifications establish the hardware baseline for running the test build. Both tiers require Windows, broadband internet, DirectX 12 compatibility, and an SSD. The recommended tier also raises memory and video-memory targets for a smoother experience.
| Component | Minimum | Recommended |
|---|---|---|
| Operating system | Windows 10 64-bit, updated | Windows 11 64-bit, updated |
| Processor | Ryzen 5 1600 or Core i5-8400 | Ryzen 5 3600 or Core i7-8700 |
| Memory | 12 GB RAM | 16 GB RAM |
| AMD graphics | Radeon RX 470 | Radeon RX 6700 XT |
| NVIDIA graphics | GTX 970 or GTX 1060 | RTX 3060 Ti |
| Intel graphics | Arc A580 | Arc B580 |
| Video memory | 3 GB | 8 GB |
| Storage | SSD required | SSD required |
| Network | Broadband connection | Broadband connection |
| DirectX | DirectX 12 compatible | DirectX 12 compatible |
For storage planning, check the free-space reading on the drive where the launcher will install the beta. A drive can show enough room for a download while lacking enough room for extraction, patching, or shader preparation.
Use the launcher’s displayed install requirement as the immediate target, then keep additional free space available before starting the download. This reduces installation failures caused by temporary files.
The published driver guidance lists NVIDIA 610.47, AMD 26.7.1, and Intel 32.0.101.8861. Updating before launch can also help shader preparation and reduce avoidable compatibility problems.
How to Download and Preload the Beta
The beta can be downloaded separately through the relevant digital storefront or PC launcher. Early Access is scheduled for eligible players from 11:00 AM PT on August 21, 2026, while the Open Beta begins at 10:00 AM PT on August 28, 2026.
| Beta window | Start | End | Eligibility |
|---|---|---|---|
| Early Access | 11:00 AM PT, August 21, 2026 | 10:00 AM PT, August 25, 2026 | Pre-order, pre-purchase, or valid beta code |
| Open Beta | 10:00 AM PT, August 28, 2026 | 10:00 AM PT, September 1, 2026 | All players on supported platforms |
Prepare your account and drive
Sign in with your Activision Account and confirm that the target SSD has enough available space for the package, updates, and temporary installation data.
Open the correct storefront
Search for the separate Call of Duty: Modern Warfare 4 Beta listing on Xbox, PlayStation 5, Steam, Battle.net, or Nintendo Switch 2 when that platform’s window becomes available.
Start the download
Select Install or Download, then allow the launcher to complete the package. Do not assume the main Call of Duty installation will begin the beta automatically.
Preload before the weekend
Eligible Early Access players can preload from August 20, 2026. Open Beta players can preload from August 26, 2026.
| Platform | Download route | Launch location |
|---|---|---|
| Xbox Series X|S | Microsoft Store | My Games & Apps |
| Xbox on PC | Xbox PC app | Xbox PC library |
| PlayStation 5 | PlayStation Store | Home screen or Game Library |
| Steam | Steam Store and Library | Steam Library |
| Battle.net | Call of Duty game-version selector | Battle.net Call of Duty page |
| Nintendo Switch 2 | Nintendo eShop | HOME Menu |
If the beta listing does not appear, verify the current access window, platform availability, region, and Early Access eligibility before troubleshooting the installation.
Performance Preparation Before Your First Match
Shader Preloading is included for PC players during the beta. It prepares graphics shaders before gameplay so the system has less shader processing to perform during a match. This can reduce some stutters and waiting, although results vary by hardware and driver configuration.
| PC platform | Shader preparation guidance |
|---|---|
| Battle.net | Shader Preloading begins after the beta is installed |
| Steam | A first-boot shader compilation is still required; later preloading supports updates |
| Both launchers | The process uses some system resources while running |
TPM 2.0 and Secure Boot must be enabled for PC players who want to play the beta online. These Windows security features support the anti-cheat environment, and disabling either requirement can prevent online access.
Before Launch:
- Confirm the beta is installed on an SSD
- Update Windows and your graphics driver
- Enable TPM 2.0 and Secure Boot
- Allow shader preloading to finish when possible
- Keep spare SSD space for patches and temporary files
Install the beta first, update the driver and operating system, restart the PC, then allow shader preparation to complete before entering a match.
If an update requires a restart, close the beta and relaunch it after the patch is applied. During the beta, restart behavior can vary by platform and by whether a data patch arrives while the game is running.
