# Example: Improved particle system performance in 4.4
extends GPUParticles3D

func _ready():
    # 4.4 automatically optimizes particle culling
    amount = 10000  # Can handle more particles smoothly
    process_material.emission_rate_hz = 1000.0

Compilation Speed Boost

# New AudioStreamPlayer3D features in 4.4
extends AudioStreamPlayer3D

func setup_advanced_audio():
    # Enhanced doppler effect
    doppler_tracking = AudioStreamPlayer3D.DOPPLER_TRACKING_PHYSICS_STEP
    
    # New attenuation models
    attenuation_model = AudioStreamPlayer3D.ATTENUATION_LOGARITHMIC
    
    # Improved spatial blend
    area_mask = 0b1111  # Better layer control

Networking Improvements

MultiplayerAPI 2.0 Enhancements:

• Reduced network latency by up to 30%
• Better NAT traversal support
• Enhanced security features

Animation Timeline Overhaul

The animation system received significant attention:

# 4.4 Updated syntax:
get_viewport().get_visible_rect().size

# New helper methods in 4.4:
extends Node2D

func _ready():
    # Improved screen size detection
    var screen_size = DisplayServer.screen_get_size()
    print("Screen size: ", screen_size)

3. Asset Re-import Recommendations:

• Textures: Re-import for better compression
• 3D Models: Take advantage of improved mesh optimization
• Audio files: Benefit from new audio processing
