Latest Release
v1.3.1 -
  • Combined per-mesh and per-triangle polygon sort options into a new and improved per-strip option. This new option isn't as accurate as our per-pixel option, but it improves on both of the previous options for users without OpenGL 4.5 support.
  • Refactored thread synchronization code between emulation and graphics thread to reduce CPU usage and improve performance on dual core systems.
  • Added support for JIT compiling the AICA's ARM CPU code for a ~10% perf gain.
  • Optimized scheduler code for a ~5% perf gain.
  • Optimized basic block linking code.
  • Sort mode of passes not always being correctly honored (Tony Hawk menus).
  • Sorting of punch through polygons (Test Drive Le Mans car decals, SGGG Segagaga menus).
  • Alone in the Dark rebooting when selecting a character with the HLE BIOS.
  • Ignore window resize events on minimize to avoid renderer restarts.
  • License screen not showing when using the HLE BIOS.
