Unreal Engine running slow? Find the bottleneck. Fix the frame time.
Rendrify helps game developers and studios diagnose and resolve Unreal Engine performance issues, from stuttering and GPU bottlenecks to costly rendering passes. Every engagement focuses on measurable, documented improvements.
The hatched segment is the 1.6 ms that pushed every frame past the 60 fps budget. Rendrify works in frame time rather than frame rate, because averages hide the spikes players feel.

"We've collaborated on multiple high volume projects with demanding render requirements, and they've been a reliable force every time. Fast, efficient, and technically sharp. They consistently optimized our pipeline without sacrificing visual fidelity. Their speed and problem-solving made a huge impact."

02 / Specialization
The problems Rendrify is brought in for.
Performance only. No gameplay or feature programming, so the attention stays on where your frame time goes.
01
GPU and rendering bottlenecks
Expensive passes, overdraw, shadows, post processing and materials that eat the GPU budget.
02
Game Thread and CPU cost
Tick, Blueprint, animation, physics and draw-call submission holding the frame back.
03
Stutter and frame-time spikes
Hitches, traversal stutter and the spikes an average FPS counter hides.
04
Shader compilation and PSO stalls
First-use hitches in packaged builds and gaps in precaching.
05
Lumen and Nanite cost
Understanding what UE5 features actually cost on your target hardware, and scaling them.
06
VRAM and memory pressure
Texture budgets, streaming pool pressure and assets heavier than they need to be.
07
Streaming and loading
Level streaming, World Partition and load-time hitches.
08
Packaged build regressions
Builds that run worse than the editor, and regressions between versions.
03 / Services

A concise, prioritized findings report
Recommended next steps, explained
Not included
Implementation of fixes
Unlimited profiling
Any guaranteed FPS increase
Broader investigations, which are quoted separately
Existing clients, live products and teams that need recurring technical support. Up to 8 specialist hours per month at the entry scope. Response terms, task boundaries and availability agreed up front. Larger engagements individually quoted.
No. The first message is a conversation about your problem, target hardware and goals. I reply with the most suitable next step. Any actual profiling happens inside a written, paid scope, which is usually a Performance Audit.
Will you sign an NDA?
Yes. Rendrify is NDA-friendly, and most engagements run under one. Project details, numbers and builds stay confidential unless a client approves publication.
Which engine versions do you work with?
Unreal Engine 4 and Unreal Engine 5, including Lumen, Nanite, virtual shadow maps and the profiling tooling that ships with each version.
Can you guarantee a specific frame rate?
No, and you should be careful with anyone who does before profiling your project. What Rendrify commits to is measurement: identifying where frame time goes, prioritizing by measured cost and validating changes before and after wherever the result can be measured.
Do you do gameplay or feature programming?
No. That is a deliberate line. The work is performance: rendering, CPU and GPU cost, stutter, memory and streaming. If the problem turns out not to be a performance one, I will say so.
Who actually does the work?
I do. Rendrify is founder-led, so the person profiling your project is the same person you talk to. There is no account manager relaying messages.
How is pricing set?
The Performance Audit is a fixed price for a defined scope. Sprints, release work and ongoing support have starting prices, with final effort and deliverables set in a written scope. Prices are in USD, excluding applicable taxes.
