EXPRESS PERFORMANCE MOD - Realistic Rush-Hour Traffic + FPS Boost v1.0

🚛 EXPRESS PERFORMANCE MOD — Realistic Rush-Hour Traffic + FPS Boost

Stop lowering your graphics. The real FPS killers in ETS2 are AI traffic, rain and micro-vegetation — this mod re-engineers all three at the definition level, and makes the world feel MORE alive doing it.

• Most "performance mods" just delete traffic and leave you driving in a dead world. This one replaces the game's flat, always-heavy traffic density withreal 24-hour traffic curves— buttery FPS at night, believable congestion exactly when a real European motorway would have it.
• 
  

• ⏰ Rush-Hour Traffic Engine — 8-point hourly density curves

• Morning rush 6:30–9:00 and evening rush 16:30–19:00 — traffic builds up and dissolves like real life
  
• 3 AM feels like 3 AM — near-empty motorways, just you and long-haul truckers
  
• AI trucks keep realistic night presence (freight never sleeps)
  
• Big-city density rebalanced — the single worst FPS zone in the game, now smooth
  
• ETS2-exclusive tuning: border crossings, rapid-transit buses and depot traffic rebalanced too
• 
  
• ⚡ Under the hood — what actually changes
• Global AI vehicle cap: 50 → 35 (direct CPU relief, fewer background simulations)
  
• Spawn distance 600m → 500m, despawn 700m → 650m (AI stops eating frames beyond what you can see)
  
• Detail grass density scaled to 40% across 400+ vegetation definitions + draw distance 105m → 80m (GPU relief, visually near-identical at speed)
  
• Rain probability cut ~4x, thunderstorms rare — heavy weather is the #1 GPU spike in ETS2
  
• Night city traffic heavily trimmed (vanilla ETS2 spawns almost rush-hour density at midnight!)
  
• Trees, buildings, road detail, shadows: 100% untouched — zero visual downgrade where it matters
• 
  
• ✅ Clean & Safe
• Pure definition overrides — no physics, no economy, no save-game edits
  
• Compatible with truck, trailer, sound and map mods
  
• Convoy-friendly (flagged optional — friends don't need it to join you)
  
• ETS2 1.60.x / 1.61

📌 Load order

Low priority (near the bottom of the in-game list). Map mods with custom traffic keep their own rules.

🎯 Best places to feel it

Berlin, Paris or Duisburg at virtual 7–8 AM vs 2 AM. Same street, completely different world — and your frame counter will notice.

🎁 BONUS: CONFIG FPS BOOST — free extra frames in 2 minutes

The biggest hidden FPS leak in ETS2 is mirrors — each one re-renders the whole scene. These config tweaks cut that cost with almost no visual difference. Works perfectly alongside this mod:

1. Close the game completely
   
2. Open Documents\Euro Truck Simulator 2\config.cfg with Notepad
   
3. Find each line below (Ctrl+F) and change its value:

uset r_mirror_view_distance "120" (default 400 - mirrors stop rendering distant traffic) uset r_mirror_scale_x "1" (if yours says 2 - mirror resolution back to normal) uset r_mirror_scale_y "1" (if yours says 2) uset r_deferred_mirrors "1" (if yours says 2 - lighter mirror lighting) uset r_ssao "1" (if yours says 2 or 3 - ambient occlusion low, barely visible) uset g_reflection "2" (if yours says 3 - reflections one step down)

1. Save the file and launch the game
   
2. Important: don't change graphics presets in Options afterwards — the game will overwrite your tweaks

Expected combined result (mod + config): +25–45% FPS in big cities depending on hardware and time of day. Your values may differ slightly — just set them to the numbers shown above.

⭐ If this smoothed out your drive, a thumbs-up and favorite helps other truckers find it!
