Rust is one of the more demanding survival games on PC, particularly for a title of its visual style. The minimum spec asks for an i7-3770 and 10GB of RAM higher than many more visually complex games. This is because Rust simulates a full persistent world with hundreds of players, base building physics, resource nodes, animals, and NPC raids all running simultaneously. A budget build will run it, but the recommended spec is where the game becomes genuinely smooth.

Rust Performance Guide
Rust has a well-known performance reputation it can run poorly even on high-end hardware in certain conditions. Large bases with many entities (doors, furnaces, chests, turrets) in close proximity cause significant CPU load. This is a game design limitation, not something settings can fully address.
The most impactful settings to reduce are Shadow Quality and Grass Displacement. Draw Distance also matters significantly on large open maps. From my experience, reducing these three settings alone can improve performance by 30-40% on mid-range hardware without dramatically changing the gameplay visibility.
