  20 missions.
• Corrected full-bright lamp halos and scene-lit lamp fixtures.
• Removed duplicated/distance-dependent SPFX fallback rendering.
• Synchronized ordered HUD/letterbox transitions with the original retail
  viewport and radio state.

Validation

• MSVC Release suite: 18/18.

• SyphonFilterPC-0.1.0-public-test.14-win64.zip.sha256

Changes

Mission flow and localization

• Restored the authored mission-failure screen for scripted objective and
  parameter failures: original fade, type-on text and one reliable restart
  path replace the unlabelled black screen.
• Added complete Russian translations for mission-parameter and
  mission-objective failure messages, including partial type-on states.
• Polished mission startup with a calmer prompt reveal, a short transition into
  gameplay and correct composition of native and retail fades.

Presentation and performance

• Corrected compact pickup sizing and made world callouts reveal and fade at a
  consistent speed from 30 through 240 presentation FPS.
• Added a smoothed presentation FPS and frame-time counter which reports host
  presentation performance independently of the original 20 Hz game logic.
• Split the monolithic PsyCross scene viewer into focused runtime, render,
  world, model, texture, HUD, pause, effects, save and presentation modules.
• Reduced repeated allocations and unchanged scene calculations while keeping
  renderer, audio and texture-residency behavior covered by regression tests.

Validation

• Windows MSVC Release build and full test suite.
• Windows PsyCross Release build, full suite and supported USA v1.1 ROM probes.
• Release manifest, executable parity, internal/external SHA-256 and
  forbidden-file audit.

Changes

Campaign and gameplay

• Restored the complete mission-completion chain: save prompt, occupied-slot
  overwrite confirmation, FMV playback and transition to the next mission.
• Preserved the campaign frontier when replaying an earlier unlocked mission.
• Resolved manual-aim ownership conflicts with auto-targeting, retained Gabe's
  final aim heading and restored crouch/diagonal movement behavior.
• Corrected danger-meter release and stabilized enemy weapon drops across the
  original 20 Hz logic and high presentation frame rates.

Rendering

• Restored original MENU.HOG weapon artwork across the pause-menu arsenal.
• Restored both lower-subway bomb models and their resident SPFX textures.
• Fixed subway train and sign corruption by publishing one coherent SCRIM copy
  phase to every affected texture page and bank.

  through containers and original status messages.
• Added held weapons to character shadows, stabilized multi-light selection and
  floor/wall projection, and kept emissive lamps at authored brightness.

  animation. Letterbox bars now appear only during mission introductions.
• Cached unchanged lighting work at the 20 Hz guest tick for steadier 60–240 FPS.

Audio, UI and localization

• Reworked native audio timing and VAB one-shot decoding to reduce latency,
  underruns, skipped samples and restart artifacts.
• Restored the voice-volume preview sound.
• Kept original English optic captions in the Russian pack and prevented
  Russian objective text from leaking into the English interface.
• Added focused regression tests for the new campaign, renderer, bridge,
  localization and audio behavior.

Validation

• Windows MSVC Release build and full non-ROM test suite.
• Windows PsyCross Release build, full non-ROM suite and supported USA v1.1
