As of 10 November 2026, there are no official PC system requirements for Warhammer 40,000: Dawn of War IV. Steam only states that the game requires a 64-bit processor and operating system, and lists both the minimum and recommended specs as “Coming soon”. The game launches on 3 December 2026, with the Commander Edition playable from 30 November. Below you will find what is officially known, where Steam Deck, Mac and consoles stand, and why we are not giving you any numbers yet.
What Steam lists
The Steam store page is the only place where publisher Deep Silver lists any requirements. Here is the state as of 10 November 2026:
| Item | Minimum | Recommended |
|---|---|---|
| Operating system | Coming soon | Coming soon |
| Processor and OS | 64-bit | 64-bit |
| CPU, memory, graphics | not listed | not listed |
| Storage | not listed | not listed |
The publisher has not announced the download size or a pre-load window either, so we do not know yet how much disk space to set aside. You can check the current state on the Steam store page.
Why we are not listing any numbers
You will find tables online with specific CPUs, graphics cards and memory amounts. None of them come from developer KING Art Games or the publisher; they are estimates from sites that calculate requirements on their own. That is why we do not repeat them here, not even as “reportedly”. We also do not derive anything from the older games in the series, because Dawn of War IV is made by a different studio from the previous games, so the comparison would tell you nothing.
As soon as the publisher publishes the requirements, we will rewrite this article and add both the minimum and recommended specs. If you pre-order, keep in mind that you are buying before the requirements are known. The 10% discount runs until launch, and prices and edition contents are in our editions and price guide.
Steam Deck
As of 10 November 2026, Dawn of War IV has no Steam Deck compatibility rating. Valve’s report is empty, which means the game has not been tested: it is not Verified, Playable or Unsupported. The publisher has not mentioned Steam Deck support anywhere. Whether and how the game will run on the Deck is not officially known.
Controller support is a related question. Steam does not list controller support for the game, and the publisher has not said whether you will be able to play with a gamepad.
Mac, Linux and consoles
The game launches only on Windows PC via Steam. Steam lists no Mac or Linux version, and the official FAQ only mentions Windows. No console version has been announced; the publisher lists PC only. Since the game launches on a single platform, crossplay does not apply.
| Platform | Status as of 10 November 2026 |
|---|---|
| Windows PC (Steam) | yes, launches 3 December 2026 |
| Mac | no |
| Linux | no |
| Steam Deck | no rating |
| Consoles | not announced |
Steam Cloud and Family Sharing
According to its Steam categories, the game supports Steam Cloud, so your saves sync between PCs. It also supports Family Sharing, which means you can share the game within your Steam family.
