Quick Answer<\/span>Subnautica 2 \u2192<\/a><\/div>\n

To increase FPS in Subnautica 2, lower the Global Illumination and Shadow Quality settings, as these Unreal Engine 5 features are the most taxing on hardware. Disabling Global Illumination alone provides a 30% FPS boost. Additionally, enabling DLSS or FSR provides a significant performance bump. Subnautica 2 utilizes UE5’s Lumen for dynamic lighting, which requires at least an RTX 30-series or RX 6000-series GPU for stable 60 FPS at 1080p.<\/p>\n<\/div>\n
