Recommended settings
Upscaling — FSRBalanced+55% FPS
This Unreal Engine 5 RPG supports all three upscalers plus UE5’s own TSR. The biggest FPS gain available — turn it on before touching anything else.
Fog QualityLow+14% FPS
Volumetric fog across Avalon's moody zones — one of the heaviest settings on this Unity game (which uses rasterized lighting, not ray tracing). High→Medium is a big win with a modest atmosphere hit.
Shadow QualityLow+12% FPS
Shadow resolution and virtual shadow map detail. One of the best FPS-per-visual trades in UE5 games.
Effects QualityLow+8% FPS
Spell effects, fire and particles. Lowering helps most in busy combat.
Vegetation QualityLow+8% FPS
Grass and forest density across the open zones — one of the heavier, most impactful settings outdoors.
SSAOOff+5% FPS

View DistanceMedium+3% FPS
How far detailed objects render. Lowering causes pop-in, so we cut it only when needed.
Post ProcessingMedium+2% FPS
Bloom, motion blur and other screen effects. Cheap to lower and barely visible in motion.
Texture QualityEpic-1% FPS
Surface sharpness. Nearly free if it fits your VRAM — 8GB cards can keep this high.
