I will optimize high performance unity3d systems
Renato W
About this gig
Are you facing frame drops, high memory usage, physics hiccups, or draw call bottlenecks in your Unity3D project? I provide expert-level performance engineering and code refactoring to get your application running smoothly across PC, Mobile, and XR/VR platforms.
What I Can Do For You:
- Deep Profiling & Diagnostics: Complete CPU, GPU, and Memory leak analysis using Unity Profiler and Frame Debugger.
- Architecture & Refactoring: Garbage Collection (GC) minimization, multithreading, and DOTS / ECS / Burst compiler integration.
- Rendering & Shaders: Custom HLSL shader optimization, draw call reduction, dynamic batching, and GPU instancing.
- XR & Physics Tuning: Frame-rate stabilization for VR/AR (Meta Quest, OpenXR) and physics engine tuning.
Why Work With Me?
- Decades of software engineering experience specializing in high-performance simulation and real-time interactive systems.
- Clean, production-ready C# code and documented optimizations.

FAQ
What do I need to provide to get started?
To get started, I will need access to your Unity project (via Git repository or a secure download link), your target platform/hardware specs (e.g., Meta Quest 3, low-end Android, PC), and a brief description of the issues you’re experiencing (e.g., frame drops during combat, long loading times)
How will I know what performance improvements were actually made?
Transparency is priority #1. You will receive a detailed Before & After Profiling Report featuring metrics from the Unity Profiler and Frame Debugger. This includes exact data on frame rate (FPS), frame time (ms), draw call counts, GC allocations, and memory savings.
Will refactoring my code break my existing game logic or mechanics?
No. Code refactoring is performed with extreme care to preserve your core gameplay logic and architecture. My focus is on eliminating bottlenecks, reducing Garbage Collection (GC) spikes, and optimizing data structures—not altering your design intent. All changes are cleanly written and documented
Do you support VR/XR and Mobile platforms?
Yes! Platforms like Meta Quest (OpenXR) and Mobile devices have strict thermal limits and frame-time budgets (e.g., maintaining 72/90 FPS in VR). I specialize in targeted optimizations for constrained hardware, including draw call reduction, GPU instancing, and physics engine tuning.
Is my code and intellectual property (IP) kept strictly confidential?
Absolutely. Your intellectual property is 100% secure. Your project files will only be used for profiling and optimization work, and will be permanently deleted from local environment upon order completion. I am also open to signing a Non-Disclosure Agreement (NDA) if required.
