  • Completely eliminates TBDR driver draw call discards on Adreno 650 by clamping all scissor bounds against the active framebuffer.
  • Restores full 3D HUD elements: speedometer dials, item balloons, position numbers, minimap player markers, and racer portraits.
• Locked 60 FPS Mobile Presentation:
  • Original 2x (480p internal resolution) baseline with 2x MSAA for sustained 60 FPS on Snapdragon 865 without thermal throttling.
  • Hardware Early-Z (LRZ) rejection enforced via strict LESS depth test comparisons.
  • Silenced blocking per-draw diagnostic stderr logging to protect internal flash storage.
• Handheld Ergonomics & Input Flow:
  • Native Android 13 sticky immersive edge-to-edge mode (LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES).
  • Automatic on-screen touch button suppression upon hardware controller detection (SDL_NumJoysticks() > 0).

DKR-R v1.0.14 — Android Handheld Optimization & HUD Restoration

DKR-R v1.0.14 — Android Handheld Optimization & HUD Restoration

This standalone release delivers critical rendering fixes and handheld optimizations for Qualcomm Snapdragon 865 and modern Android retro handhelds (including Retroid Pocket 5, Odin 2, and RP4 Pro).

---

What's New & Fixed in v1.0.14

1. Restoration of 3D HUD & In-Game UI Elements

• Resolved Vulkan Scissor Rect Underflow (VUID-00282): On Qualcomm Adreno 6xx/7xx TBDR GPUs, submitting negative scissor offsets (left < 0 or top < 0) caused the mobile hardware driver to discard draw calls entirely. Clamped all scissor dimensions against active framebuffer boundaries, ensuring draw calls are safely preserved.
• Restored HUD Graphics: Fixed orthographic UI scissor intersection in the framebuffer renderer, fully restoring:
  • Golden weapon/item balloons
  • Analog speedometer needles and dials
  • Player position and lap counter indicators
  • Minimap player markers and navigation arrows
  • Character select icons and portraits

2. Locked 60 FPS Mobile Performance Engine

• Tuned TBDR Mobile Defaults: Clamped baseline mobile presentation defaults to Original 2x (480p internal resolution) and 2x MSAA, perfectly balanced for Snapdragon 865 / Adreno 650 hardware to hold a steady 60 FPS without thermal throttling.
• Hardware Early-Z (LRZ) Enforcement: Maintained strict LESS depth test comparisons in RT64 so occluded fragments are rejected before shading.
• Eliminated Hot-Loop Stderr Logging: Silenced blocking per-draw diagnostic output on unsupported compute pipeline stages that previously overwhelmed runtime.log with synchronous flash writes.
• Mobile Water & Lighting Optimizations: Water reflections defaulted to Sky baseline and RTX lava lighting disabled on Android by default, avoiding costly screen-space ray marching passes.

3. Native Handheld Ergonomics

• Edge-to-Edge Borderless Display: Native Android 13 sticky immersive mode (WindowInsetsController.hide(WindowInsets.Type.systemBars())) and LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES eliminate navigation and status bar insets.
• Touch Screen Auto-Hide on Physical Handhelds: Detects hardware controllers on boot (SDL_NumJoysticks() > 0) to automatically suppress touch buttons and the [ MENU ] overlay.
• Fixed Landscape Orientation: Screen orientation locked to landscape (android:screenOrientation="landscape") to eliminate gyro sensor tilting or unexpected display flipping.

DKR-R v1.0.13 — Android Handheld Optimization & Modern Defaults

DKR-R v1.0.13 — Android Handheld Optimization & Modern Defaults

This standalone release delivers native Android handheld optimizations for Qualcomm Snapdragon 865 and modern Android retro handhelds (such as the Retroid Pocket 5, Odin 2, and RP4 Pro).

What's New & Fixed in v1.0.13

1. Fullscreen Edge-to-Edge Display

• Added Android 13 sticky immersive mode (WindowInsetsController.hide(WindowInsets.Type.systemBars())) and LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES.
• Window creation now properly passes SDL_WINDOW_FULLSCREEN, eliminating status bar and navigation bar insets for true edge-to-edge 16:9 widescreen presentation.

2. Touch Screen Menu Button & Overlay Hiding

• Added physical controller auto-detection on boot (SDL_NumJoysticks() > 0): on-screen touch controls and the [ MENU ] button automatically hide on launch when running on physical handhelds with built-in controls.
• Enabled "Visible" toggle in the touch layout editor, allowing users to hide the Menu button manually if desired.

3. High Performance 60 FPS Engine Refinement

• Eliminated Hot-Loop Stderr Logging: Silenced blocking per-draw fprintf(stderr) calls on unsupported compute shader stages, preventing thousands of synchronous flash writes to runtime.log per second that were starving the render loop.
• Tuned Mobile Water Reflection Defaults: Defaulted mobile water reflections to Sky baseline and disabled RTX lava lighting on Android by default, preventing heavy screen-space ray marching that overwhelms mobile TBDR architectures.
• Restored Hardware Early-Z (LRZ): Enforced strict LESS depth comparison in RT64, ensuring Qualcomm Adreno TBDR GPUs reject occluded fragments early for locked 60 FPS performance.

4. Fixed Display Rotation & Gyro Flipping

• Changed android:screenOrientation from sensorLandscape to fixed landscape in AndroidManifest.xml and enforced it via setRequestedOrientation().
• Prevents Android from activating the accelerometer sensor and flipping the screen upside down or engaging system auto-rotate when the console is tilted.

5. Out-of-the-Box Modern Handheld Defaults

• First-run profile defaults to Modern (60 FPS manual refresh rate, 16:9 Expand aspect ratio, 480p 2x resolution, Fullscreen window mode).
