SDL3
Cross-platform C library for windowing, input, audio, and GPU-accelerated graphics.
Recommended as a cross-platform layer that handles windowing, input, rendering and hardware details,12 with reported latency gains over SDL2 and a GPU API that newcomers find easier than Vulkan.34 The main caveat raised is fiddly fullscreen mode handling during migration,5 and one commenter notes that adoption has been slow.6
Why people recommend it
Platform abstraction · 3
Commenters say it abstracts windowing, controllers, rendering and hardware across platforms without imposing a game engine.
