LAUNCH OPTIONS (COPY & PASTE) CHANGE MaxMem command
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Add these via Steam - Library - Right-click Rust - Properties - General:
-nolog -high -force-d3d11 -maxMem=YOUR RAM IN MB -graphics.shadowmode 0 -gc.buffer 4096
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
ONLY LAUNCH OPTIONS THAT ACTUALLY WORK RN
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
-nolog → Minimizes certain logging.
-high → Sets Rust to high CPU priority.
-force-d3d11 → Ensures DirectX11 mode.
-maxMem=16384 → Caps usable memory to ~16GB.
-gc.buffer 4096 → Allocates 4GB for garbage collection (16GB+ RAM recommended).
-graphics.shadowmode 0 → Disables shadows on startup.

MOUSE4 BIND FOR FPS BOOST

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HELPS A LOT FOR LOWER-END PCs
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• graphics.shadowmode 0 → Removes shadows.
• reflection.planarcount 0 / reflection.planarreflections false / reflection.planarresolution 0 → Disables reflections.
• effects.clearallgibs / decal.clear → Removes debris and decals that pile up.
• playercull.enabled true + playercull.maxplayerdist 400 → Culls distant players.
• gc.buffer 4096 → 4GB garbage collector buffer (16GB+ RAM recommended).
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
EXTRA / SITUATIONAL COMMANDS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• gc.collect / gc.alloc / gc.incremental_milliseconds 1 → Clears or manages memory, can stutter briefly.
• pool.clear_* → Frees memory pools when usage spikes.
• pool.enabled → Toggles memory pooling (leave enabled for best reuse).
• sss.enabled false → Disables sub-surface scattering (small effect).
• playercull.visquality 4 → Tweaks culling aggressiveness.
• graphics.maxqueuedframes 3 → Caps queued frames (possible smoother input).
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HOW TO USE THESE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• For low-end PCs, disable shadows/reflections and use culling to boost FPS.
• Clearing assets and forcing GC helps if memory usage grows, but expect a small stutter.
• “gc.buffer 4096” suits 16GB+ RAM systems; use 2048 or skip if you have less.
• Test each tweak—results vary by PC.
