Baldurs Gate 3 System Requirements: Why the Numbers Move

Baldurs Gate 3 system requirements have shifted more than once since the 2023 launch, and Larian has revised the published specs alongside patches and new platform ports. Treat any number you read here, or anywhere else, as a snapshot rather than a permanent figure, and check the listing on your storefront of choice before buying.

Why the spec sheet keeps moving

Patches change engine overhead, texture streaming and shader compilation, so requirements published at launch do not necessarily describe the game as it runs today. Storefront listings on Steam, GOG and the Epic Games Store get updated for current builds; unofficial round-ups you find elsewhere often do not.

What the platform ports tell you

• The game shipped natively for macOS, and from September 2025 natively for Linux, with the Linux build specifically tuned for Steam Deck. A studio does not commit to a native Deck build without the game running acceptably on modest, fixed hardware.
• Console versions run on PS5 and Xbox Series X/S at specs Larian controls entirely, with no card swap or overclock possible. That is the closest thing to a guaranteed baseline you will find.

Where load actually spikes

• Areas with dense NPC counts and heavy dialogue systems, more common later in the campaign, stress CPU and RAM harder than the opening zones. If your machine sits right on the minimum line, expect the back half of the game to be where it shows first.
• Storage is the figure most likely to catch you out: voiced dialogue across several languages plus cutscene assets make the install large regardless of how low you set the graphics.

The one number worth trusting

Whatever your storefront lists today, for the build you are about to download. Round-ups, including this one, describe a target that keeps moving with every major patch to Baldur's Gate 3.
