Godot Engine has evolved rapidly since the release of version 4.0. What used to be a simple comparison is now a clear shift in technology, architecture, and long-term direction.
This guide is based on official release information and documentation, focusing on real differences between Godot 3.x and Godot 4.x as of 2026.
Current Version Status (2026)
- Godot 4: 4.6.x (active development)
- Godot 3: 3.6.x (LTS maintenance)
Godot 3.6 is the final major branch of the 3.x series, designed for long-term stability.
Godot 4.x is the main development line and continues to receive major updates and improvements.
Rendering System: OpenGL vs Vulkan
Godot 3 (OpenGL / GLES3)
-
Uses OpenGL ES 3.0 renderer
-
Stable and widely compatible
-
Supports older and low-end hardware
Godot 4 (Vulkan Renderer)
Godot 4 introduces a completely rewritten renderer based on Vulkan.
Key improvements:
-
Modern rendering pipeline
-
Better GPU utilization
-
Support for advanced techniques such as:
-
SDF-based global illumination
-
GPU particles
-
Dynamic soft shadows
3D Engine: Major Upgrade
Godot 3
-
Basic physically based rendering (PBR)
-
Limited lighting system
Godot 4
- Real-time global illumination (SDFGI)
- Volumetric fog
- Improved shadows and materials
- Advanced rendering pipeline
Later updates introduced:
-
Rendering pipeline improvements (4.3)
-
FSR 2.2 support (4.2)
-
Animation and rendering optimizations
Physics Engine Changes
Godot 3
- Uses Bullet Physics engine
Godot 4
-
Uses GodotPhysics (native)
-
Optional Jolt Physics integration (4.4+)
Scripting Improvements (GDScript)
Godot 3
- Simple scripting language
- Limited typing
Godot 4
-
Static typing support
-
Better performance
-
Improved editor tooling
Animation System Improvements
Godot 3
- Basic animation tools
Godot 4
-
Improved animation trees
-
Better blending and control
-
More flexible workflows
Performance and Optimization
Godot 3
- Lightweight and stable
- Works well on low-end hardware
Godot 4
- Better GPU usage
- Improved multithreading (4.1+)
- Continuous optimization updates
Recent versions focus on performance tuning and editor responsiveness.
Web and Platform Support
Godot 3
- Basic web export
- Limited performance
Godot 4
-
Improved WebAssembly support
-
Better browser compatibility
Key Improvements Across Godot 4 Versions
-
4.0: Vulkan renderer, major rewrite
-
4.1: Multithreading improvements
-
4.2: Animation and rendering upgrades
-
4.3: Rendering pipeline improvements
-
4.4: Jolt physics integration
-
4.5–4.6: Performance and workflow optimization
Comparison Table
When to Use Godot 3
-
Maximum stability required
-
Existing projects
-
Low-end hardware targets
When to Use Godot 4
-
New projects
-
Modern rendering or 3D needs
-
Long-term support
Final Verdict
Godot 3 is a stable long-term support solution, but development has slowed significantly.
Godot 4 is now the primary platform, with modern rendering and continuous improvements.
For most new projects in 2026, Godot 4 is the recommended choice.
