  • Set 'Material Quality' and 'Texture Quality' to 'Low' High impact

    These settings consume VRAM and GPU resources. On a GTX 1660 (6GB VRAM), keeping them low is crucial for consistent frame delivery, particularly during intense moments.

  • Set 'Detail Quality' and 'UI Quality' to 'Low' Medium impact

    Reducing these settings further lessens the load on your GPU, helping to prevent VRAM overutilization and subsequent stuttering.

  • Disable 'V-Sync' and 'Anti-Aliasing' High impact

    V-Sync can introduce input lag and stuttering if frames drop below your refresh rate. Anti-Aliasing (MSAA) is resource-intensive; disable it for performance.

  • Set 'Bloom', 'Distortion', and 'First Person Shadows' to 'Off' Medium impact

    These visual effects add GPU load. Disabling them frees up resources, contributing to smoother frame times.
