Unreal Engine 5 Optimization Guide: Stop the Stutter

Struggling with stuttering in next-gen UE5 titles? Here are the best settings to tweak for maximum FPS.

Unreal Engine 5 titles look stunning, but they bring older hardware to its knees. UE5 heavily relies on software upscaling to achieve playable framerates.

Crucial Settings to Lower

  • Global Illumination (Lumen): Drop this to Medium. It saves 15% of GPU load with minimal visual loss.
  • Volumetric Clouds & Fog: High to Medium yields a massive 20% FPS boost.
  • Upscaling (DLSS/FSR): Absolutely mandatory. Set to "Quality" for 1080p, and "Balanced" for 1440p.
