SDL3 Starter Kit

Welcome to the SDL3 Starter Kit, a high-performance 2D rendering small engine designed to leverage the power of modern shaders and the new SDL3 GPU pipeline.

This kit provides a rock-solid foundation for any developer looking to build smooth, modern 2D games capable of handling thousands of entities with zero lag.

✨ Key Features

• High-Performance GPU Batching: Render over 10,000 animated sprites at 500+ FPS (depending on hardware).
• Universal Gamepad Support: Native handling for Xbox, PlayStation, and Switch controllers with auto-detection and analog stick support.
• Retina & 4K Ready: Built-in High DPI support for crystal-clear visuals on all modern displays.
• Professional Architecture: Clean separation between headers (/include) and source code (/src).
• Smart CMake: Automatic downloading and configuration of SDL3 and SDL3_image via FetchContent.
• Player Controller Included: A complete hybrid Keyboard + Gamepad controller example to get you started instantly.
