Total War: WARHAMMER 40,000 System Requirements

Players searching for Total War: WARHAMMER 40,000 system requirements in 2026 keep hitting the same wall: the Steam page for app 4199910 currently prints an operating-system line and almost nothing else. This guide repeats what Creative Assembly and SEGA have actually listed, explains why the gap exists, and tells you what that means for a PC you already own. It does not paste a fake Intel Core i5 and a made-up RTX card because a competitor site needed a table.

If you are choosing whether the game is even for you, start with how to play. If you are waiting on a key, use the wishlist and beta tool. If you need the calendar rather than the spec sheet, read the release date update. Console players should skip the missing GPU column entirely and read console controls instead.

What Steam lists today

As of the current store page:

• Minimum OS: Windows 10 64-bit
• Recommended OS: Windows 11 64-bit

That is the published PC requirement. Processor, memory, graphics, DirectX, storage, and additional notes are not filled in. Steam Deck compatibility is listed as Unknown. The release date field is still To Be Announced even though CA confirmed a 2027 year around Gamescom. None of those empty cells are an invitation to guess.

When a later patch or a beta client fills the table, this page will change. Until then, treat any site that already quotes a CPU model or a gigabyte count as repeating WARHAMMER III numbers, not 40k numbers.

Why the table is empty on purpose

Total War: WARHAMMER 40,000 is not a Warscape reskin with bolters glued on. CA built a new engine — publicly discussed as WarCore / Warcore in anniversary and Gamescom coverage — because the campaign is galactic and because battles simulate thousands of projectiles through ruins instead of resolving a melee blob. Game director Attila Mohacsi has called the galactic scale one of the reasons the old foundation was not enough. IGN’s Gamescom hands-on named WarCore in the takeaways. You do not copy-paste a 2022 recommended GPU onto that sentence and call it journalism.

The other reason the numbers will move is the content CA is actually rendering. This is the studio’s first 18-rated Total War. Eurogamer watched Orks run into a firing line and erupt. Blood is in the game without a paid gore pack. Alpha Strike showed per-entity line of fire, simulated tracers, Baneblade sweeping fire, and mixed-model infantry on maps full of destructible cover. PC Gamer’s own Bilibili recap joked that you should weep for your graphics card. That is colour, not a benchmark. It is also a warning that a machine which runs WARHAMMER III at 1080p is not automatically cleared for a 2027 40k battle.

Specs for a closed beta later in 2026, specs for a review build, and specs for the 2027 gold master will not be the same document. Steam’s OS line is a floor for the storefront, not a promise that Windows 10 will be the day-one minimum forever.

Platforms that are actually confirmed

CA and SEGA have announced:

• PC via Steam (app 4199910) and the Epic Games Store
• PlayStation 5
• Xbox Series

This is the first mainline Total War designed for DualSense and Xbox controllers as well as mouse and keyboard. That does not change the missing PC table, but it does change who should care. If you only own a last-generation Xbox or a PS4, you are not in the listed set. If you own a Series console or a PS5, your “can I run it” answer is the storefront listing when it appears, not a YouTuber’s 4080 benchmark.

Mac and Linux are not in the current announcement. Steam Deck remains Unknown. Do not plan a Deck launch party on a field Valve has not scored.

How to prep a PC without fake numbers

You can still do useful work:

1. Confirm the machine is 64-bit Windows 10 or 11. That is the only published bar.
2. Update GPU drivers from NVIDIA, AMD, or Intel. A new engine plus thousands of lights and particles is exactly the workload that punishes a two-year-old driver.
3. Keep a chunk of free SSD space. CA has not named a gigabyte figure; every recent Total War has been large, and a 40k install with high-res gore and war engines will not be a 20 GB surprise. We will print the number when Steam does.
4. Wishlist app 4199910 so the news hub tells you when the table fills, when a beta depot appears, and when a recommended spec is no longer empty.
5. If you are buying a PC in 2026 to play this in 2027, buy for a modern 1080p/1440p strategy title with huge unit counts, then wait for the official line. Do not buy a card because a wiki invented an RTX number.

During the closed beta, treat hitching, pop-in, and CPU spikes as bug-report fuel, not as proof your rig is “below minimum.” There is no published minimum CPU to be below.

What the rating implies for hardware and households

The 18 / mature rating is not a spec, but it is a content warning that belongs on the same page. Steam’s mature-content note describes graphic, realistic-looking depictions of physical conflict, weapons, injury, and death. Eurogamer called the gore carnival visible. Families filtering a shared PC should treat that as settled, not as a rumour. It also implies the engine is spending budget on dismemberment, blood, and projectile density that WARHAMMER III’s fantasy battles did not have to show at this pitch.

Console versions will have their own certification SKUs. We will not invent a PS5 Pro mode or a Series S 30 fps cap. When Sony, Microsoft, or CA publish those modes, they go here.

What this page will do when numbers land

The honest version of a requirements guide, before a gold master, is a list of absences. The useful version after a gold master is a table plus a “this will still change” footnote. We will add CPU, GPU, RAM, storage, and API rows the day Steam or the Epic storefront fills them. We will mark beta-client numbers as beta-client numbers. We will not back-fill this article with WARHAMMER III’s i5-4570 and GTX 760 as if the millennium never moved.

Check Steam, check the wishlist tool, and assume your rig needs headroom for a new engine full of guns. That is the current system-requirements story for Total War: WARHAMMER 40,000.
