## 3. Chapter 2 "23/24 Notes" Solution & Lake Cave Stereo Puzzle

### Why Players Get Stuck at 23/24 Notes in Chapter 2
Chapter 2 contains **24 written notes**. The most frequently missed note (`CH2-N13`, **Adrenaline Junkie Note #2 — Balance Beam Upper Hole**) is part of a 3-note environmental mini-series left by an urban explorer:
- **Note #1 (`CH2-N12`)**: On a crate right before the narrow concrete balance beam in the flooded tunnel.
- **Note #2 (`CH2-N13`, THE 23/24 CULPRIT)**: Immediately after crossing the balance beam and exiting the tunnel mouth, **stop and turn 180 degrees to look UP above the tunnel exit arch**. There is a concealed upper alcove/hole directly above the exit doorway; climb the side ledge into that upper opening to grab the middle note.
- **Note #3 (`CH2-N14`)**: On the scaffolding ledge overlooking the drainage drop.

### Lake Cave Dock Stereo & Country-Song Swing Puzzle (`CH2-N15` & Amber #6)
In the Chapter 2 subterranean Lake Cave:
1. Walk out onto the wooden boat dock and interact with the portable stereo/boombox so it begins playing the upbeat **country song** over the cave acoustics.
2. Activating the stereo triggers the overhead rope-swing anchor above the water.
3. Back up on the dock, sprint, jump, and grapple-swing across the lake chasm to land on the hidden upper rock cavern ledge containing Note `CH2-N15` and an Amber piece.

## 6. PC Optimization & Softlock Fixes (Patch v1.0.9)

- **RTX 3080 / 4070 Frame Drops**: Unreal Engine 5 Lumen Global Illumination + Virtual Shadow Maps cause heavy GPU bottlenecks in subterranean water caves. Lower *Global Illumination* and *Shadow Quality* from Epic to **Medium** (+35–45% FPS boost) and enable DLSS/FSR Balanced.
- **Cutscene-to-Gameplay Stutter**: Disable V-Sync in-game and cap framerate to 60 or 120 FPS via NVIDIA Control Panel / AMD Adrenalin.
- **Checkpoint Respawn Softlock**: Patch `v1.0.9` (Oct 30, 2026) fixed an issue where dying immediately after picking up a key item locked doors on reload. Update via Steam or select *Restart Chapter* from the pause menu.
