The short answer
As of November 10, 2026, the official PC requirements are not published. Steam’s requirements box contains only one hard fact:
Requires a 64-bit processor and operating system. OS: Coming soon.
The recommended section repeats the 64-bit line and nothing else.

What closed beta testers reported
Treat this as unverified community talk, not a specification:
- Players in the Steam discussions describe frame drops and stutter in large late-game battles, especially at 1440p and 4K.
- Several reports say the game is GPU-bound, with GPU usage above 90%, and that players leaned on DLSS to hold frame rates.
- One frequently repeated claim is that newer high-end cards (RTX 40/50 series) were affected as often as older high-end cards — which, if true, points at optimization rather than raw power.
None of this has been confirmed by KING Art or Deep Silver, and the closed beta ran on a pre-launch build. The retail build may differ.
What to do before December 3
- Wait for the official specs. They will almost certainly appear on the Steam page before launch; that is the version to trust.
- Do not upgrade on rumor. Beta-build performance tells you very little about the release build.
- Free up SSD space. The size is unknown, but modern RTS installs are rarely small; leaving 100 GB free is a safe buffer, not a requirement.
- Check back here. We update this page when the requirements go live.
Will it run on Steam Deck?
Unknown. Valve has no compatibility rating for the game, and KING Art has not mentioned Deck support. Dawn of War IV is a classic base-building RTS with a PC-first interface; even if it launches, expect to need a mouse and keyboard layout.
