Is 8 GB of video memory enough for Baldur's Gate 3?

Can I run Baldur's Gate 3 with a GeForce RTX 3070?

Ultra in Baldur's Gate 3 is drawn around a GeForce RTX 4070 and its 12 GB. The GeForce RTX 3070 has the core for it and not the memory, which is the one shortfall no setting recovers.

Of the 7 cards that reach this same point in Baldur's Gate 3, the GeForce RTX 3070 is the slowest - index 22 is the least this game will accept for that tier among the hardware we track.

The weakest link is video memory: this rig brings 8 against the 12 that Baldur's Gate 3 asks for at the ultra tier. Everything else in the rig is already past that line.

That readout is the best this card can do in Baldur's Gate 3: it assumes nothing else in the machine holds it back. Your own processor and memory can only lower it, never raise it.

The same card with three different processors

In Baldur's Gate 3 the processor beside a GeForce RTX 3070 changes the answer, which is why a card-only verdict is not worth much here. Each row assumes 16 GB of system memory.

Processor	Index	Verdict	Bottleneck
Ryzen 5 1600	30	Will not run	processor
Ryzen 9 5900X	70	Runs at high	system memory
Ryzen 7 9800X3D	95	Runs at high	system memory

Cheapest way up one tier

video memory: Radeon RX 9060 XT 16GB

The GeForce RTX 3070 carries 8 GB of video memory and the ultra tier needs 12 GB. Video memory is a hard limit: no amount of core speed substitutes for it.

That is the smallest part in our catalogue that clears the ultra tier - not the fastest one, and not a price claim: we hold no price data, so "cheapest" here means "least upgrade that does the job".

This part alone will not get you there. graphics card also falls short of that tier.
