Unreal Optimization Guide and Practice (1080p / 60 FPS on GTX 970–1060)

This guide is designed for developers targeting 1080p / 60 FPS performance on GTX 970/1060-class GPUs using Unreal Engine 4.27–5.x.
It compiles performance budgets, best practices, and proven optimization techniques for maintaining visual quality while keeping frame times stable.

Use DirectX 11 instead of 12 on Windows plalform

Performance Budgets

Metric	Target
Frame Time	≤ 16.6 ms (60 FPS)
Draw Calls	< 3 000
Triangles	≤ 12 Million
Texture Resolution	Mostly ≤ 2K (4K for hero assets only)

---

Geometry & World

• Disable Nanite for GTX-class GPUs.
• Use Hierarchical Instanced Static Meshes (HISMA) or Instanced Static Meshes (ISM) for repeated assets.
• Always Generate LODs (even with Nanite enabled).
• Employ custom lightweight HLODs — Epic’s system can be memory-heavy.
• Replace decals with mesh cards where possible.
• Set max draw distances for small meshes and lights.
• Use simple collisions only — disable collision and Affect Nav Mesh on decorative objects.
• Use World Partition with small cells for efficient streaming.
• Aggressively manage LOD transitions and use instancing to minimize draw calls.

---

Lighting

• Prefer 1 dynamic key light + baked fill lighting.
• Use a static skylight with baked cubemaps (no real-time reflection captures).
• Avoid Lumen if possible — use baked lighting for static scenes.
• Minimize SDF and volumetric effects.
• Disable shadows on small objects; use proxy shadow casters for complex ones.
• Use capsule shadows on skeletal meshes.
• Replace volumetric fog/clouds with fake light rays (cards or shaders).
• Sphere Reflection Probes: bake and reuse cubemaps.
• A fully baked setup can ship with zero dynamic lights.

---

Materials & Shading

• Keep materials ≤ 6–8 texture samples.
• No tessellation.
• Limit parallax and bump offsets (texture-dependent).
• Prefer dithering over transparency; fake glass with cubemaps/shaders.
• Use Anisotropic Relaxed Cone instead of POM.
• Pack ORM maps to reduce texture count.
• Split alpha channels into separate textures when possible.
• Derive normal B channel from RG to save space.
• Assign all textures to proper groups for easy management.
• Set shading rate > 1×1 for VFX/skybox to reduce pixel cost.

---

Memory Management

• Pack multiple masks into one texture (slice maps).
• Avoid RGBA textures when unused channels exist.
• Albedo/Normal can be 2K, while Spec/Masks/ORM can be 1K.
• Disable “Generate Lightmap UVs” on meshes using dynamic lighting.
• Remove extra UV channels on all meshes.
• Manage the texture streaming pool — increase or optimize it to avoid VRAM thrashing.

---

Skeletal Meshes

• Reduce bone count aggressively.
• Blendshapes only for cinematics.
• Replace destruction animations with Vertex Animation Textures (VATs).
• Capsule shadows instead of complex shadow casting.
• Disable per-frame tick on non-critical Blueprints.

---

Dynamics & VFX

• Chaos Physics/Destruction is expensive — bake results where possible.
• Cloth: avoid Chaos Cloth; use dynamic bone chains or pre-baked simulations.
• Replace projectile traces with particles or ray approximations.
• Bake flipbooks for fire, smoke, or liquids instead of dynamic sims.
• Niagara: use LODs; disable particle lights at Medium and below.
• Use particle cutouts to minimize overdraw.

---

Post-Processing

• Bloom: Low
• Chromatic Aberration: Off
• Motion Blur: ≤ 0.3
• SSR/SSAO: Off or Low
• Fog: Use simple exponential fog only
• Prefer fake DOF or none

---

Scalability & Quality Settings

Default target: Medium

Setting	Recommendation
Screen Percentage	~85%
Upscaler	TAAU or FSR 2
Shadows	≤ 2 cascades, max 2048 res
SSR	Disabled
SSAO	Low/Off
Volumetric Effects	Off
Reflection Capture	Baked only

---

Shipping Low-Spec Toggle

For ultra-low hardware fallback:

r.ScreenPercentage 80
r.Fog 0
r.AmbientOcclusionLevels 0
r.Shadow.MaxResolution 1024

---

Profiling & Testing

• Use Stat Unit, Stat GPU, ProfileGPU, and Session Frontend early in development.
• Test builds on real GTX 970/1060 hardware — synthetic scaling isn’t reliable.
• Monitor VRAM usage and texture pool overflow warnings.

---

Engine Choice

💡 Alternative: Use Unreal Engine 4.27 for lighter rendering and no Lumen overhead — ideal for GTX and midrange GPUs.

---

Custom Scalability Tiers

Define your own scalability tiers in Scalability.ini rather than relying on Epic’s defaults.
Fine-tune toggles for post, shadows, and material complexity per-tier for consistent visual quality across low/mid hardware.

---

Summary

Goal: Stable 60 FPS @ 1080p on GTX 970/1060
Core Principles:

• Aggressive LODs & instancing
• Static lighting & baked reflections
• Optimized materials & texture packing
• Minimal dynamic systems (physics, lights, particles)
• Strong profiling discipline

Author Notes

Many of these practices trace back to the Unreal 2–4 era — and still work wonders in UE5.
Don’t underestimate the power of disciplined LODs, instancing, and clean material setups.
You can ship a gorgeous UE5 game on GTX-class GPUs — if you’re smart about every millisecond.
