There's very little to go on here yet. As of August 2026, Game of Thrones: War for Westeros's Steam listing gives only two things: a 64-bit processor and operating system, and a broadband internet connection. Every other field — CPU, GPU, memory, storage, DirectX — reads "coming soon" in both the absolute minimum and recommended blocks.

That's not surprising given the RTS game isn't due until 2027, and it's a wider launch window than most of the unannounced games on GameWatcher's wiki have. Expect the real figures to arrive well before launch though.
