How to Increase FPS in X-Plane 11/12 - Complete Optimization Guide (2025)

🎯 1. Setting up X-Plane graphics

🔧 Main parameters:

Textures (Textures Quality):

• weak PC: Medium

• medium: High

• Powerful: Maximum (only if VRAM ≥ 8 GB)

Antialiasing (AA):

Impacts FPS the most after clouds.

• weak: FXAA / 2x

• medium: 2x–4x

• Powerful: 4x (8x not recommended)

Shadows: turn off completely → up to +20 FPS

Reflection Detail: Minimum - the difference is visually minimal.

Cloud Quality (XP12):

The heaviest engine parameter.

Low–Medium → best performance.

🎯 2. Optimization of scenes (Custom Scenery)

Large airports and old mesh packets can eat up performance.

What to do:

• remove old versions of ORBX regions

• disable HD Mesh v4 if Ortho is installed

• clean the Custom Scenery folder from duplicates

• check library conflicts

Correct order of scenery_packs.ini:

1. Airports

2. Libraries

3. Overlays

4. Mesh / Ortho

🎯 3. Lua scripts to increase FPS

FlyWithLua allows you to disable heavy elements of X-Plane.

Best scripts:

• 3jFPS Wizard - dynamic optimization

• Clouds & Shadows tweak

• Reduce lights/shadows.lua

Gives +10–20 FPS without obvious loss of quality.

---

🎯 4. Disabling heavy plugins

Overloaded Plugins folder = FPS loss.

Temporarily disable:

• old weather plugins

• AI traffic plugins

• SAM (if not used)

• unused Lua scripts

Turn on one at a time to calculate the “heavy” mod.

---

🎯 5. Traffic optimization

AI Aircraft: set 0–2

Traffic Global: Low density

LiveTraffic: reduce refresh rate

This is +5–10 FPS instantly.

---

🎯 6. Driver settings (GPU)

NVIDIA:

• Prefer Maximum Performance - ON

• V-Sync - OFF

• Low Latency Mode - ON

AMD:

• Anti-Lag - ON

• Texture Filtering → Performance

🎯 7. Aircraft optimization

Complex airliners also load the system.

Boeing / Airbus (FF, Toliss, Zibo):

• Display refresh rate: Medium

• Remove unnecessary monitors in the cockpit

Rotate / Felis / iniBuilds:

• reduce cabin lighting

• disable wet glass effect
