TT Games has published the official PC requirements for LEGO Batman: Legacy of the Dark Knight, and the headline number is 16GB of RAM, required at every tier from minimum settings all the way up to 1440p.
Full PC specs confirmed
That figure lands at an awkward moment. RAM prices have climbed sharply over the past year, driven largely by demand from AI data centers eating up DRAM supply. Anyone still running an 8GB system who was hoping to jump into open-world Gotham City on launch day has a hardware decision to make first.
What the specs actually look like
The full requirements break down across three tiers:
All tiers require Windows 11 and a 50GB SSD. That OS requirement is worth noting separately, since Windows 10 users will need to factor in an upgrade alongside any hardware changes.
The minimum spec targets 1080p at just 30fps, and only with FSR, XeSS, or frame generation enabled. This is not a light load for older hardware.
The RAM number that caused a reaction
Here's the thing: 16GB at minimum is genuinely unusual for a game that still lists a GTX 960 as an acceptable GPU. Normally those two data points don't sit in the same row. A GTX 960 is a decade-old card, but the RAM floor matches what you'd expect from a much more demanding title.
The explanation is the open world. Legacy of the Dark Knight is built around a Gotham City that TT Games says is larger than the map in Batman: Arkham Knight, and streaming that much geometry continuously demands memory headroom that previous brick-based Lego games simply never needed. Past Lego titles were corridor-heavy and level-gated. This one isn't.
The 4K tier originally listed 32GB before community pushback prompted TT Games to revise it down to 24GB. That reduction happened before the final requirements were published, so the numbers you see now reflect the post-revision spec.
Gotham open world confirmed larger than Arkham Knight
GPU and CPU demands are actually reasonable
Outside of RAM, the requirements are more forgiving than you might expect from an open-world release. The recommended GPU tops out at 8GB of VRAM, which is a lower bar than most modern titles ask for at that tier. The CPU requirements also stay within two or three generations for most settings, meaning a mid-range build from a few years back should handle 1440p without issue.
All three tiers support DLSS, FSR, and XeSS upscaling alongside frame generation, which gives the minimum spec some breathing room. Hitting 30fps with a GTX 960 at native 1080p would be rough, but with FSR Balanced and frame generation doing the heavy lifting, it becomes more plausible.
What this means heading into May 22
LEGO Batman: Legacy of the Dark Knight launches May 22 on PC, PS5, and Xbox Series X|S, with a Nintendo Switch 2 version coming later without a confirmed date. This is TT Games' first release since Lego Star Wars: The Skywalker Saga in 2022, and the ambition here is obvious. An Arkham-style combat system, over 100 unlockable suits, and an open Gotham built from multiple Batman eras make for a very different proposition than anything the Lego series has attempted before.
The RAM requirement is the one genuine hardware barrier for budget PC players. The GPU and CPU asks are manageable. If you're on 8GB of system memory, that's the upgrade to prioritize before launch.
