We're excited to announce a new update to the Stride game engine, featuring numerous fixes and improvements across multiple areas. This release includes 55 commits and 244 file changes from 17 contributors since the last version, highlighting the amazing dedication and efforts of our community and contributors.

A huge thank you to all contributors, including the new contributors: @C0dingSteve, @MEEMexe, @ferafiks, @Kreblc3428, @Acissathar and @rmtttt.

Highlights

  • Graphics: Vulkan compute shader support by @johang88
    • Enabled compute shaders in the Vulkan backend. Shader compiler now generates GLSL compute shaders with compute intrinsics (e.g., gl_GlobalInvocationID, memory barriers), RWTexture/RWBuffer load/store, and std430 for non-constant buffers.
    • Added descriptor types: StorageImage, StorageTexelBuffer, StorageBuffer, with counts capped to device limits; added additional pixel formats.
  • UI: Gap support in layout panels by @laske185
    • Added gap spacing similar to CSS gap:
      • Grid/UniformGrid: ColumnGap, RowGap, LayerGap.
      • StackPanel: gap property.
  • Graphics: New Mesh read API
    • Adds a high-level API to efficiently read vertex and index buffers from meshes, handling varied vertex layouts and data types automatically.
  • Improvements to Bepu Physics:
    • Constraint impulse/force getters
      • Adds the ability to query the impulse and force applied by a given constraint. Enables behaviors like detaching overstressed constraints, tuning strengths dynamically, or driving strain-based audio/FX.
    • Raycast against a specific collider
      • Which, as its name implies, adds a way to raycast directly against a chosen collidable, ignoring others that may be in the way.
    • Contact handling refactor, child index lookup, impact force evaluation
      • Easier contact iteration, exposes pre-collision linear/angular velocities, provides an impact force evaluation helper, and reports compound child indices.
      • But introduces a breaking change, by replacing IContactEventHandler with IContactHandler to simplify and future-proof the contact API.
  • Major performance improvements:
    • UI performance: Avoid GPU stalls in batching
      • Ensures temporary buffers used by UI batching are only released on the next draw instead of directly after use, avoiding stalls caused by writing to those buffers while in flight. Reduces MapSubresource duration by ~98% per call, leading to a reduction of 1.96ms per frame in a UI-heavy scene.
    • Engine performance: Revert slow memcpy path
      • Restores MemoryCopy based fast path instead of Unsafe.CopyBlockUnaligned where safe, keeping unaligned copies for platforms that require it. Reducing CPU frame prep time by ~40% in a draw-call heavy scenes.
