  • Game Version: 20260502.12303.W

  • Platform: steam windows

  • Mods: Hair, clothes, tattoos, and others.

  • Hardware Specifications & Operating System (OS version, CPU, GPU, RAM: Windows 11 Intel Core i5-12450H NVIDIA GeForce RTX 3050 (4GB VRAM) 500 GB NVMe SSD

  • Issue Date: May 7, 2026

  • Error Message: Visual bug: Character reflections not appearing in mirrors when using SSGI on mid-range hardware."

  • Details: I am reporting a successful configuration to enable Lumen Character Reflections on mid-range hardware (RTX 3050 4GB), which was previously problematic. Through extensive testing, I found a “sweet spot” that balances visual fidelity and thermal stability.

  • The Solution:

  • Reflections: Switched from SSGI to Lumen.

  • Optimization Settings: Enabled the newly added Weather Update, LOD, and Character Optimization features.

  • Frame Rate Management: Set the in-game limit to 100 FPS and applied a strict 58 FPS lock via NVIDIA Control Panel.

  • Performance Result: This setup provides a fluid 60 FPS-like experience with fully functional mirror reflections.

  • Technical Observations:

  • GPU Temperature: Remains stable at 86°C under heavy load without thermal throttling.

  • VRAM Management: The “Optimization” mode effectively manages the 4GB VRAM limit while running Lumen features.

  • I have attached a video demonstrating these settings and the resulting performance. I hope this data helps optimize the game further for mid-range laptop

I have specifically configured the game to run on the ‘High-performance NVIDIA processor’ via the NVIDIA Control Panel to ensure the RTX 3050 is fully utilized and stable.
