UE5 and Unity performance

Hit your framerate. Ship on schedule.

Production engineering and technical art for complex Unreal Engine and Unity projects. We find engine-level bottlenecks, optimise the rendering pipeline and make data-driven fixes that hold performance without giving up visual quality.

~20%frame time improvement

4.6×draw call reduction

2.5msframe time saved

0/409VSM dynamic invalidations

UE5 ships hot. Unity scales fast. Projects regress quietly.

Performance debt compounds. One unoptimised material or a few hundred extra draw calls can become a late-stage shipping delay. Our job is to find your technical ceiling before players do.

GPU

Overdraw and shader cost

Complex translucent materials and dense assets drop frames in the most intense scenes.

Draw calls

Scene complexity creep

Un-instanced geometry and redundant content overload the CPU and render thread on lower-spec hardware.

Memory

Asset bloat at runtime

Inefficient streaming pools and VRAM use cause traversal hitches and platform-mandated crashes.

Profiling, optimization and technical art across the pipeline

Performance profiling

Deep analysis with RenderDoc, Unreal Insights and PIX to locate CPU and GPU bottlenecks.

GPU optimization

Draw call reduction, LOD strategy and geometry processing.

Scene and asset pipeline

Automated asset validation and level streaming to remove hitching and manage World Partition.

Materials and shaders

Custom HLSL that balances fidelity against instruction cost for each target spec.

Memory engineering

VRAM pool management and leak diagnosis for platform-constrained hardware.

Platform and QA

Target-specific tuning for PC, console and SoC-limited mobile, including certification support.

Case study one

From bottleneck to a 20% performance gain

UE5 open world. Profile-driven optimization of a high-fidelity environment.

12.43msframe time, 2.5ms saved

280draw calls, down from 1,313

3.6×fewer triangles

~20%overall performance gain

Geometry

Nanite and overdraw

Static mesh optimization and custom Nanite settings cut overdraw in dense foliage and kept hero asset complexity in check.

Lighting

Virtual shadow maps

Tuned VSM caching and resolution removed shadow stalls during time-of-day shifts and local point light use.

Rendering

Shader complexity

Refactored master materials to lower HLSL instruction counts and reduce translucent sort cost.

Core engine

Scene management

World Partition streaming distances and component culling were tuned to stabilise the render thread and stop hitching.

Case study two

Memory budget audit: 4.9 GB to 3.3 GB

UE5 Memreport, RHI non-transient memory. A 33% reduction overall.

Tutorial-sequence hero assets stayed resident after players moved into the open world, overflowing pools on 8 GB hardware. Aggressive streaming overrides, a texture group refactor and lower idle memory for non-visible assets freed room for VSM caching.

Peak memory was 18.4 GB in the open world against 2.85 GB on the tutorial map. A 6.5× delta like that belongs in World Partition streaming logic, not a global budget cap.
