125 GB SSD, 32 GB RAM and Windows 11 Required: Warhammer 40,000: Dawn of War IV PC System Requirements Revealed
With less than three weeks remaining before the battle for Kronus begins anew, developer KING Art Games and publisher Deep Silver have officially unveiled the full PC hardware specifications for Warhammer 40,000: Dawn of War IV. Set to launch on December 3, 2026 (with a three-day early access window kicking off on November 30 for Commander Edition owners), the real-time strategy sequel draws a firm hardware line on its official Steam store page: mechanical hard drives and Windows 10 are officially left behind.
Windows 11 and a 125 GB SSD Required Across the Board
The first standout detail in the hardware sheet shared by the creators of Iron Harvest is the operating system baseline: 64-bit Windows 11 is listed as mandatory for both minimum and recommended tiers. Storage is equally demanding, requiring 125 GB of available space on an SSD just to get through the door, while the studio explicitly recommends an NVMe SSD to stream high-resolution unit assets and destructible battlefields without hitching.
That hefty footprint reflects the massive scope of the package arriving on day one. As we covered in our breakdown of how Dawn of War IV packs over 70 missions on Kronus, four dedicated campaigns, and classic base building, the game launches with four fully realized armies featuring distinct unit rosters and sync-kill animations: the Space Marines (Blood Ravens and Dark Angels), the Orks, the Necrons, and the series debut of the Adeptus Mechanicus.

Minimum and Recommended PC Specifications
While GPU demands remain approachable,starting at a 6 GB GeForce GTX 1660 or Radeon RX 5700 paired with 16 GB of RAM,the recommended tier doubles system memory to 32 GB of RAM. Keeping framerates locked when dozens of Kastelan Robots, Ork Boyz, and Redemptor Dreadnoughts clash in full-scale base assaults also calls for an Intel Core i7-12700 or AMD Ryzen 5 7600X alongside an 8 GB RTX 3060 Ti or Radeon RX 9060.
| Component | Minimum Specifications | Recommended Specifications |
|---|---|---|
| Operating System | Windows 11 (64-bit) | Windows 11 (64-bit) |
| Processor (CPU) | Intel Core i5-10600K or AMD Ryzen 5 2600X | Intel Core i7-12700 or AMD Ryzen 5 7600X |
| Graphics (GPU) | NVIDIA GeForce GTX 1660 or AMD Radeon RX 5700 (6 GB VRAM min.) | NVIDIA GeForce RTX 3060 Ti or AMD Radeon RX 9060 (8 GB VRAM min.) |
| Memory (RAM) | 16 GB RAM | 32 GB RAM |
| Storage | 125 GB available space (SSD) | 125 GB available space (NVMe SSD) |

NVIDIA GeForce NOW Support Confirmed at Launch
Alongside the PC specs, KING Art Games and Deep Silver confirmed that Warhammer 40,000: Dawn of War IV will be playable on NVIDIA GeForce NOW at launch. Players whose rigs fall short of the 32 GB RAM target or who cannot spare 125 GB on their primary drive will be able to stream their Steam library copy directly through NVIDIA's cloud servers across solo campaigns, skirmishes, and co-op Last Stand sessions.
Pre-orders on Valve's storefront currently carry a 10% launch discount, bringing the Standard Edition down to $53.99 (regularly $59.99) and the Commander Edition to $80.99 (regularly $89.99), which unlocks the game 72 hours early on November 30 in a thriving season for PC strategy fans that also saw solo-developed WW2 RTS Spearhead shake up Steam.
My Field Notes
massivestrong>32 GB of RAM and a mandatory 125 GB NVMe SSD drop during the night shift immediately reminded me of the hardware debates Heimdall and I keep having over modern strategy engines. Unlike a linear corridor shooter, bringing back full-scale Kronus attrition with classic base building, persistent battlefield wreckage, and hundreds of infantry units locked in synchronized melee executions puts tremendous pressure on CPU cache and system memory. The GPU floor is surprisingly forgiving with a GTX 1660 at minimum and an RTX 3060 Ti at recommended, but dropping Windows 10 support and demanding a 125 GB SSD block will force plenty of Dark Crusade veterans to clean out their drives before November 30.
Reviewing the spec sheet beside me, Maëlle "Kaelen" pointed out why the storage and memory numbers make sense: "When you factor in four full faction campaigns, more than 70 missions, and the Adeptus Mechanicus fielding screen-filling cybernetic legions against Ork hordes, you can see exactly where those 125 gigabytes go. Confirming day-one GeForce NOW support right alongside the requirements is a smart move for commanders who want to jump into Last Stand co-op without upgrading their RAM kit first." Now we just need to see how smoothly KING Art's engine holds up when Monoliths and Redemptor Dreadnoughts start trading fire on December 3.
