Modern Warfare 4 PC Preload: File Size & Launch Times

Call of Duty: Modern Warfare 4 PC preload is live. Discover global launch times, modular install sizes, day-one drivers, and how to avoid shader stutter on PC.

Direct Answer: Preloading for Call of Duty: Modern Warfare 4 on PC is officially live across Battle.net, Steam, and PC Game Pass. The full global multiplayer launch unlocks on Friday, 23 October 2026, at 9:30 AM IST (04:00 UTC / 12:00 AM ET). Download sizes are modular: players who only want Multiplayer need ~80 GB (including the base Call of Duty HQ engine), while the full package with the single-player Campaign requires ~124 GB. To prevent day-one micro-stutters, update to the latest Game Ready drivers, set your GPU shader cache size to 10GB+, and allow in-menu shader compilation to reach 100% before queuing.

Global Launch Times & Preload Schedule

Preload servers are active right now, allowing players to decrypt files before Friday's server opening. Unlike console rolling midnight releases, the PC release features a synchronized global launch:

Modular Download Sizes: How Much Storage Do You Need?

Activision continues its modular installation structure through the unified Call of Duty HQ launcher. You do not need to download the entire game if you only intend to play multiplayer:

• Call of Duty HQ (Base Engine & Shared Assets): ~42 GB *(Mandatory)*
• Modern Warfare 4 Multiplayer Pack: ~38 GB *(Required for online 6v6, Ground War & Gunfight)*
• Single-Player Cinematic Campaign Pack: ~44 GB *(Can be uninstalled after completion)*
• High-Resolution Asset Streaming Cache: 16 GB to 32 GB *(Configurable dynamic texture cache)*
• Total Standard Install (MP + Base): ~80 GB
• Total Full Install (Campaign + MP + Base): ~124 GB

Preventing Day-One Launch Stutter: Three Critical Steps

Day-one PC launches for competitive shooters are frequently plagued by frame drops caused by real-time shader compilation and disk I/O bottlenecks. Follow these three steps during preload to ensure smooth, high-FPS gameplay:

1. Expand Your GPU Shader Cache to 10GB

By default, Windows and GPU drivers restrict shader cache storage to 4GB. When games like Modern Warfare 4 exhaust this buffer, older shaders are purged and recompiled mid-match, causing sudden frame-time spikes:

• NVIDIA Control Panel: Go to *Manage 3D Settings* > *Global Settings* > *Shader Cache Size* > select 10 GB or Unlimited.
• AMD Software: Adrenalin Edition: Go to *Gaming* > *Graphics* > *Advanced* > ensure *Shader Cache* is enabled and reset if upgrading from a previous driver.

2. Complete 100% In-Menu Shader Pre-Caching

When you first launch Modern Warfare 4 on Friday morning, do not immediately jump into matchmaking. Watch the top-left status indicator as the game compiles shaders across all multiplayer maps. Letting this reach 100% on the main menu guarantees stutter-free 1% low frame rates during gunfights.

3. Install on a Dedicated Gen4 or Gen5 NVMe SSD

Modern Warfare 4 heavily utilizes high-speed texture streaming to stream photorealistic 2K and 4K textures from your storage drive directly into VRAM. Installing the game on a slow SATA SSD or mechanical hard drive will cause texture pop-in and draw-call lag. A fast NVMe drive like the Crucial P510 1TB M.2 NVMe Gen5 SSD delivers instantaneous asset decompression.

Day-One Graphics Drivers: Download Before Launch

Both major GPU vendors have released dedicated launch drivers featuring game-specific optimizations and bug fixes:

• NVIDIA GeForce Game Ready Driver: Includes day-one profiles for DLSS 5 Neural Reconstruction, Reflex ultra-low latency, and fixes for dynamic shadow flickering.
• AMD Radeon Software Adrenalin: Features day-one HYPR-RX and Anti-Lag 2 support for Radeon RX 7000 and 8000 series GPUs.

Make sure to install your GPU driver update *before* launching the game so your shader pre-caching builds cleanly on the latest driver binaries.
