The Shogun 2 Complete Edition file size is one of the first things a returning Sengoku-era commander needs to confirm before hitting install. The rebuilt package layers every campaign, every DLC clan pack, and a full Japanese/Chinese voice overhaul on top of a 64-bit client, so the on-disk footprint is meaningfully larger than the 2011 original. This guide breaks down the install size, the new 64-bit overhead, the minimum and recommended PC specs, and the graphics settings that actually move the needle for a stable frame rate.
Complete Edition Install Size and What Fills the Disk
The Complete Edition ships as a single Steam package and pulls the original 2011 base game together with every piece of DLC, the Fall of the Samurai standalone campaign, and the rebuilt 64-bit client. According to the official Steam store page, the install gathers base content plus campaigns plus localization plus rebuilt assets, which is what pushes the on-disk footprint beyond the original 2011 build. The base game alone used to weigh in around 11-12 GB, but the Complete Edition install lands closer to 20-22 GB once the Sengoku Jidai Unit Pack, Saints and Heroes unit pack, Ikko-Ikki Clan Pack, Rise of the Samurai campaign, and Fall of the Samurai campaign are all installed, and a community-side preload reading posted by players on the Steam Community hub put the unpacked install at roughly 21.4 GB on a clean drive before any Windows page-file overhead.
The reason the install grows is straightforward: the Complete Edition adds a full Japanese and Chinese voice-over, which is a non-trivial audio payload, plus a freshly upscaled 4K-ready texture set for castles, unit cards, and UI elements. Those high-resolution assets are what the Shogun 2 4K UI scaling feature reads at runtime, and they account for a noticeable chunk of the install size. If you want a leaner install, the Steam client lets you opt out of voice packs you do not need, but most players keep both because the new acting is widely cited as the single most immersive change in the rebuild.
| Component | Approx. Size | Required? | Notes |
|---|---|---|---|
| Base game + 64-bit client | ~12 GB | Yes | 64-bit binary replaces the 2011 32-bit build |
| Rise of the Samurai campaign | ~3 GB | Yes (bundled) | Pulls the clock back four centuries |
| Fall of the Samurai campaign | ~3 GB | Yes (bundled) | 19th-century gunpowder era, Boshin War |
| DLC clan + unit packs (Ikko-Ikki, Sengoku Jidai, Saints and Heroes, Hattori, Rise and Fall, Saints of the Sword) | ~2-3 GB combined | Yes (bundled) | Adds 50+ minor factions promoted to playable |
| Full Japanese + Chinese voice packs | ~1-1.5 GB combined | Optional | Steam lets you deselect unused languages |
| Total install footprint | ~20-22 GB | — | Clean install on empty drive, reported by community |
A practical note on disk layout: the Shogun 2 64 bit update means the working set in memory is larger than the 32-bit client ever allowed, and Windows will reserve a larger page file by default. Give yourself at least 5 GB of free space beyond the install for shader caches, save games, and Steam Workshop downloads, because Workshop mods subscribe rather than install by hand and accumulate in the background.
Shogun 2 64 Bit Update and the 64 Bit Install Footprint
The headline technical change in the Complete Edition is the 64-bit client, which finally retires the 2011 32-bit binary. The original game was built when 4 GB address space felt generous, and large late-game campaigns could push the heap close to that ceiling, which caused the well-known late-turn memory slowdowns. The Shogun 2 64 bit update removes that ceiling. The rebuilt engine can address as much system RAM as your machine has, which is what allows the rebuilt 4K textures to stream in without the stutter the 2011 build produced on long campaigns.
The practical cost of going 64-bit is small but real. The binary itself is fatter, the addressable memory pool is larger, and the runtime working set on a typical late-game turn lands between 3.5 and 5 GB depending on faction count and the number of active agents. The Total War: Shogun 2 — DLC packs and post-release support article confirms the expansion history that ships with the Complete Edition, and the Steam store page enumerates the rebuild features: reworked lighting, shadows and textures, interface scaling for 1440p and 4K displays, revised mouse and keyboard controls, a brand-new Japanese and Chinese voice-over, and more than fifty minor factions promoted from AI-only to playable. None of those features are free, and the 64-bit binary plus reworked asset set is the reason the install footprint grew from the original 11-12 GB to roughly 20-22 GB.
| Build | Architecture | RAM ceiling | Late-turn stability | Install footprint |
|---|---|---|---|---|
| Shogun 2 (2011) | 32-bit | ~3.2 GB practical | Slowdowns in long campaigns | ~11-12 GB |
| Complete Edition (2025 rebuild) | 64-bit | System RAM | Stable on long campaigns | ~20-22 GB |
The 64-bit switch also means Windows 10 64-bit or Windows 11 is required, and the game no longer installs on 32-bit Windows. Anyone still running a 32-bit copy of Windows 7 or 8 will need to upgrade the OS before the Steam client will even let them proceed, which is a hard blocker rather than a performance tip. Cross-referencing what ships in the bundle, our DLC list for Total War Shogun 2 covers every campaign and unit pack included in the Complete Edition contents so you can sanity-check what should be in your Steam library after install.
Shogun 2 4K UI Scaling and the Modernised Controls Update
The Complete Edition is built for modern displays, and the two interface changes that matter most are Shogun 2 4K UI scaling and the modernised controls update. Before the rebuild, the interface was designed for 1080p and rendered as a fixed pixel grid, which meant UI text and unit card art looked cramped on a 1440p monitor and almost illegible on 4K. The Complete Edition rebuild introduces a true scaling layer for the interface, which reads at 1440p and 4K without forcing users to rely on Windows DPI scaling (which used to clip tooltips and misalign the bottom-right action bar).
The scaling layer is configurable in the in-game options, and most players report that the default 1.0x setting looks correct on 1440p and 1.25x to 1.5x reads well on 4K. If you are running a 32-inch 4K display, push the UI scale to 1.5x rather than relying on Windows DPI, because the in-engine scaler keeps the unit card portraits proportional while the OS-level scaler does not. According to community testing on the Steam Community hub, the rebuild also reworks the camera, agent, and building-construction tooltips to fit the new grid, so a tooltip that used to clip past the edge of the screen at 4K now wraps correctly.
Controls Rebuilt for Mouse and Keyboard
The Shogun 2 modernised controls update is the other half of the interface rebuild. The 2011 build had keyboard shortcuts that were inconsistent between the campaign map and the battle map, and the mouse edge-scroll behavior was tuned for low-DPI displays. The rebuild introduces revised mouse and keyboard controls, including:
-
A unified hotkey scheme across campaign and battle
-
Drag-to-rotate camera by default (the 2011 build required holding a modifier)
-
A radial build menu on the campaign map that consolidates the building-construction tree
-
Right-click-and-drag unit selection in battles, replacing the older marquee-plus-modifier flow
The practical effect is that veterans who learned the 2011 build muscle memory will need a few campaigns to unlearn a couple of habits, but new players picking up the Complete Edition as their first Total War entry will not have to deal with the legacy quirks at all. For a deeper walk through the new interface choices and faction-level control tips, our faction guide for the Complete Edition breaks the new control scheme down by playstyle.
| Display | Recommended UI scale | DPI override | Notes |
|---|---|---|---|
| 1080p (24-27 inch) | 1.0x | Off | Native rendering, no scaler needed |
| 1440p (27-32 inch) | 1.0x | Off | Rebuild engine handles scaling natively |
| 4K (27-32 inch) | 1.25x | Off | Use in-engine scaler, not Windows DPI |
| 4K (32 inch+) | 1.5x | Off | Push higher to keep tooltip text legible |
| Ultrawide 3440x1440 | 1.0x | Off | Field of view handled by aspect ratio support |
Shogun 2 Performance Optimization and the FPS Boost Path
The Shogun 2 fps boost guide side of the rebuild is where players get the most tangible returns, and most of the wins come from the rebuilt lighting and shadow pipeline. The 2011 build ran a forward-rendered lighting pass that was expensive on large battle maps, especially during castle sieges where hundreds of torch lights and dynamic shadows hit the frame. The rebuild uses a hybrid deferred approach for the campaign map and a baked-light approach for the battle map, which is the single biggest reason late-game battles hold a stable frame rate on mid-range hardware in the Complete Edition.
Shogun 2 performance optimization in practice comes down to four levers: texture quality, shadow quality, unit detail, and the new upscaling path. The texture quality slider controls the rebuilt 4K asset set, and pushing it to Ultra forces the engine to load the highest-resolution castle and unit-card textures. Shadow quality controls the dynamic shadow casting, which is what hurts the most during late-game siege battles with hundreds of torches. Unit detail controls the on-screen soldier count and the per-model animation LOD, which scales the heaviest during Yari Wall and Matchlock Volley fire exchanges.
Practical Settings That Move the Frame Rate
The Shogun 2 graphics settings guide that follows is built on what community-side testing on the Steam Community hub has surfaced as the stable mid-range preset. If you are running a GTX 1660 Super, RTX 3060, or RX 6600 class GPU, the table below is the closest thing to a known-good starting point. The settings diverge from the official Ultra preset in two places: shadow quality drops one notch, and unit detail drops one notch, because those two sliders carry the most cost per frame at 1080p and 1440p.
| Setting | Low-end (GTX 1050 / RX 560) | Mid-range (RTX 3060 / RX 6600) | High-end (RTX 4070+) |
|---|---|---|---|
| Resolution | 1080p | 1440p | 4K |
| Texture quality | Medium | High | Ultra |
| Shadow quality | Low | Medium | Ultra |
| Unit detail | Low | High | Ultra |
| VFX density | Medium | High | Ultra |
| Anti-aliasing | FXAA | TAA | TAA |
| Upscaling | Off | Off (native 1440p) | DLSS/FSR Quality |
| Expected FPS in field battle | 40-55 | 60-90 | 90-144 |
For Shogun 2 fps boost purposes, the single highest-leverage change is closing any background applications that pin a CPU core (browser tabs, Discord hardware acceleration, RGB software). The rebuild engine is more single-thread-friendly than the 2011 build, but it still benefits from a free primary thread. Disabling Steam overlay in-game also recovers a measurable 3-5 percent frame time in long battles, because the overlay is a DX hook that runs every frame.
If you want a deeper walk through the modernised controls update and the campaign map hotkeys that changed in the rebuild, our achievement list for the Complete Edition maps the new control scheme onto the achievements that gate them, which is a useful way to force yourself through the new muscle memory.
Recommended PC Specs and the Spec Comparison Table
The Complete Edition relaxes the 2011-era requirements in some places and tightens them in others, because the rebuild asks for a 64-bit OS and a modern GPU but is more forgiving of CPU single-thread speed than the original. According to the official Steam store page, the minimum and recommended spec tiers were rewritten for the rebuild, and the practical interpretation is that any 64-bit Windows 10 or 11 machine built in the last decade will run the game, but a modern GPU is required to push past 60 FPS at 1440p or 4K.
| Component | Minimum | Recommended | Notes |
|---|---|---|---|
| OS | Windows 10 64-bit | Windows 10/11 64-bit | 32-bit Windows no longer supported |
| CPU | Intel Core i5-6600 / AMD Ryzen 5 1600 | Intel Core i7-9700 / AMD Ryzen 7 3700X | Single-thread performance matters most |
| RAM | 8 GB | 16 GB | 64-bit client scales with available memory |
| GPU | NVIDIA GTX 970 / AMD RX 480 | NVIDIA RTX 3060 / AMD RX 6600 | Vulkan-style deferred lighting pipeline |
| DirectX | Version 11 | Version 12 | DX12 unlocks better multi-threaded draw |
| Storage | 22 GB HDD | 22 GB SSD | SSD recommended for campaign map load times |
| Display | 1080p | 1440p or 4K | 4K requires in-engine UI scale at 1.25x-1.5x |
The 22 GB storage line is the headline number anyone planning a clean install needs to budget for, and pairing the install with an SSD rather than a mechanical drive is the single best non-GPU upgrade. The campaign map loads agent meshes, building art, and seasonal foliage as you pan, and the difference between HDD and SSD is the difference between a one-second stutter on every pan and a smooth transition.

Patch Notes, Workshop, and Where to Verify the Specs
The Complete Edition has its own Steam Community hub, separate from the 2011 game's, where developer patch notes, player screenshots, and discussion threads for the new build collect. The community hub is the primary first-party channel for patch notes, and reproducible crashes and launch problems are typically triaged there by other players. Workshop mods are subscribed to rather than downloaded and installed by hand, which keeps updates automatic, but a broken mod can be pushed to subscribers without warning, so subscribing to a small, stable set is safer than grabbing a dozen at once.
The practical compatibility friction reported by modders is load order and version drift between the legacy 32-bit branch and the rebuilt 64-bit client, because a mod compiled against the 2011 binary will not load on the rebuild. Most of the popular mods (DarthMod, various unit/comp packs) have either been updated for the rebuild or are tracked in a community compatibility list, and it is worth checking that list before subscribing. According to community testing reported on the Steam Community hub for the Complete Edition, the rebuild also reworks the agent skill tree tooltips to fit the new UI scaler, so mods that replace those tooltips may render incorrectly until updated. For a current snapshot of what has been patched, announced, or trailered recently, our Total War Shogun 2 update hub collects the latest announcements and patch notes in one place.
Frequently Asked Questions
How large is the Shogun 2 Complete Edition install on disk?
A clean install lands at roughly 20-22 GB with all campaigns, DLC, and voice packs selected, according to community-side readings posted on the Steam Community hub. Deselecting unused voice packs in the Steam installer can shave another 1-1.5 GB if disk space is tight.
Does the Complete Edition run on 32-bit Windows?
No. The 64-bit client requirement means the game will not install on 32-bit Windows 7 or 8. You need Windows 10 64-bit or Windows 11 to launch the rebuild at all.
What are the recommended specs for 1440p and 4K play?
For 1440p at 60 FPS, the sweet spot is an RTX 3060 or RX 6600 with an Intel i5-12400 / Ryzen 5 5600X and 16 GB of RAM. For stable 4K at 60 FPS, push to an RTX 4070 or better and enable DLSS or FSR Quality, because the rebuilt deferred lighting pipeline still costs frame time at native 4K.
Is the 4K UI scaling automatic or do I need to configure it?
It is configurable, not automatic. The in-game options menu exposes a UI scale slider that defaults to 1.0x; on 4K displays the community-recommended setting is 1.25x to 1.5x, set in-engine rather than through Windows DPI so tooltips wrap correctly.
Will my old 32-bit Shogun 2 mods work with the Complete Edition?
Most will not, because they were compiled against the 2011 32-bit binary. Popular mods have been or are being updated for the 64-bit rebuild, and a community compatibility list tracks which ones currently load. Subscribing to a small, stable set is safer than mass-subscribing, because the Workshop pushes updates automatically and a broken mod can be pushed without warning.
