Rust System Requirements
The official PC specs from Steam, copied exactly. Rust needs 45 GB of space and — realistically — an SSD and 16 GB of RAM to be worth playing.
Requires a 64-bit processor and operating system.

What Actually Matters
Reading a spec sheet for Rust is a bit misleading, because the bottleneck usually isn't your GPU. Rust is far more sensitive to RAM and storage speed than most shooters — it streams a huge procedural world, and a big populated server with a lot of built structures will eat memory that a benchmark never touches.
That's why 12 GB is the floor and 16 GB is the real target, and why the recommended spec lists an SSD as requiredrather than nice-to-have. If you're scraping the minimum, more RAM and an SSD will do more for you than a GPU upgrade will.
If you meet the specs and it still runs badly, that's usually settings rather than hardware — Rust ships with some genuinely expensive defaults.

Frequently Asked Questions
How many GB is Rust?expand_more
45 GB. That's the figure Steam lists for both minimum and recommended, and Facepunch specifically recommend it be on an SSD — the recommended spec lists an SSD as required, not optional.
Can my PC run Rust?expand_more
If you're on Windows 11 64-bit with at least 12 GB of RAM and roughly a GTX 1060 / RX 470 or better, you clear the minimum. But minimum in Rust means playable, not pleasant — Rust is CPU and memory hungry, and the recommended 16 GB plus an SSD is much closer to what you actually want.
Do I need an SSD for Rust?expand_more
The recommended spec says 'SSD Required' outright, and the minimum spec warns you'll get 'longer than average load times' without one. Rust streams a lot of world data, so a mechanical drive hurts more here than in most games. Treat an SSD as effectively mandatory.
Is 8GB RAM enough for Rust?expand_more
No — the official minimum is 12 GB, and recommended is 16 GB. 8 GB is below the floor Facepunch publish, so expect heavy stuttering or a game that simply won't hold up. RAM is the single most common reason Rust runs badly on otherwise decent machines.
Does Rust run on Steam Deck?expand_more
Steam lists Rust as Unsupported on Steam Deck. It isn't a compatibility rating we'd argue with — Rust's anti-cheat and performance profile make handheld Linux a rough fit.
