Out of MemoryHigh

Rust Crash Out of Memory & Garbage Collection Lag Stutter Fix

Optimal Launch Parameters for Rust

-fullscreen -highSteam / Launcher

-fullscreen

Bypasses Desktop Window Manager (DWM) composition buffer for lower input lag.

-high

Sets CPU thread priority to High in Windows Task Scheduler.

Anti-Cheat Integrity: Easy Anti-Cheat (EAC) & Cerberus

Ensure your third-party antivirus (Windows Defender, Kaspersky, Bitdefender) whitelists the main game executable. Over 70% of launch crashes and untrusted file warnings are false-positive real-time scanning locks.
