Rendering

GPU-Accelerated Rendering

Blade uses wgpu to render across every GPU backend from a single codebase. The entire frame draws in just two instanced draw calls.

  • Vulkan, Metal, DX12, and WebGPU backends
  • Glyph atlas with row-based bin packing
  • Damage tracking - only re-render on changes
  • 60+ FPS under heavy output
