Warhammer 40,000: Dawn of War IV lists Windows 11 as its only supported operating system. Gagadget's report that Windows 11 is a hard gate is only half right. The game's own developer says Windows 10 can run it, but without official support.

KING Art and publisher Deep Silver published the PC requirements on November 12, ahead of the December 3 launch. The Steam page lists Windows 11, a 64-bit processor and OS, 16 GB of RAM, and 125 GB of available storage as the minimum.

Storage125 GB available space125 GB available space

Gagadget's write-up, like some other outlets, describes the recommended tier as needing an NVMe SSD. Steam's page lists only "125 GB available space" for both tiers and doesn't name a drive type. GameGPU's coverage says NVMe is advised for a comfortable experience. I can't confirm that from the Steam listing, so treat it as a likely suggestion rather than a published requirement.

Nobody has published frame-rate targets or the resolution and settings those tiers are meant to hit. "Minimum" tells you the game should launch. It doesn't tell you how smooth it will be.

Windows 10: not supported, but not blocked​

In a November 12 FAQ on Steam, KING Art said the game can run on Windows 10. It listed Windows 11 because Microsoft has ended official support for Windows 10. The studio gave three caveats:

  • Players who got into the closed beta should also be able to run the full game at launch.
  • Neither Windows 10 nor Linux is officially supported.
  • KING Art can't guarantee ongoing compatibility with future updates.

KING Art also said it has seen reports of beta players running the game on Linux. That is anecdotal, and the studio makes no promise about it.

This matters for anyone with a Windows 10 PC that can't take Windows 11 because of the TPM or CPU requirements. You may be able to play at launch. A later patch could still break things, and support staff are likely to point to the requirements list if you hit problems. Players who bought or tested on Windows 10 should check the Steam community page after each major update.

RAM and storage​

KING Art says 16 GB is a true minimum. It calls 32 GB recommended for a smoother experience but not required. Systems with 24 GB can run the game too, though available memory depends on what else is open.

The 125 GB storage figure includes headroom. The studio says the game currently needs about 100 GB, including roughly 25 GB of cutscenes. The extra 25 GB is meant to cover future updates and downloadable content.

Practical checks before you buy:

  1. Check installed and free RAM in Task Manager's Performance tab. With a browser, Discord and launchers open, 16 GB gets tight.
  2. Confirm you have more than 100 GB free, ideally the full 125 GB, on the drive where Steam will install the game.
  3. Check your GPU against the list. The Gagadget report says the minimum calls for 6 GB of video memory or more, though Steam's listing doesn't state that.
  4. Confirm whether your Windows 11 install is current and 64-bit.

Release, pricing and GeForce NOW​

The game releases December 3, 2026. Steam shows the standard edition at $59.99, discounted 10% to $53.99 in a pre-purchase promotion that ends December 3. The Commander Edition is $89.99, or $80.99 with the discount. It starts advance access on November 30. Prices may vary by region.

KING Art and Deep Silver also confirmed the game is coming to NVIDIA GeForce NOW. GameGPU notes a 64-bit OS is required either way. GeForce NOW streams supported games from your Steam library, so it could suit owners of weaker or Windows 10 PCs. Neither company has said which tiers or performance levels will apply.

Steam currently shows no user reviews, so there are no launch-day performance reports yet. If your PC sits near the minimum, waiting for early player feedback is a sensible move. The game is PC-only through Steam, and no console versions have been announced.

Bottom line​

The Windows 11 requirement is real on paper, but it reflects Microsoft's support lifecycle more than a technical block. If you're on Windows 10, the developer's position is that it should work for now, with no promises. If you're near the RAM or storage floor, budget for 32 GB and plenty of free SSD space.
