Unity Overdraw: Improving the GPU Performance of Your Game
A single thing has killed the GPU performance of thousands of mobile games: the famous Unity Overdraw. Do you know what overdraw is doing to you?
Unity Launch Performance Risk Scorecard
If your Unity build feels “mostly fine,” you might still be one spike away from a milestone slip. Here’s the launch risk scorecard I use to translate
2026.02 - Agentic Optimization
Agentic Optimization: You already know the pattern: profiler finds pain, the team patches random code, and frame time still looks like a heart attack. In this lesson, you move from agentic profiling into agentic optimization so you stop guessing.
Unity 6.2 -> 6.3 Upgrade: 5 Reasons Your Frame Time (and Build Times) Might Finally Chill
Your frame-time graph looks fine… until Tilemaps instantiate, audio spins up, or URP "records" the frame. That “one hitch” is why retention drops and reviews go
Unity 6.2 vs 6.1: Worth the Upgrade?
Unity 6.2 (6000.2) has a bunch of performance work that’s not just “micro-optimizations.” The big themes: * Fewer main-thread stalls during async loading * Meaningful URP regression
2026.01 - Agentic Profiling
Agentic Profiling: You hit Ctrl+7, record a capture, open the Profiler Timeline, and… your frame time graph still looks like a heart attack. Better ways to do this? Yeah, plenty!
2025.12 - The Few Groups You'll Ever Need: Mipmap & Culling Groups
The Few Groups You'll Ever Need: Mipmap & Culling Groups: Texture shimmer and off-screen simulation waste are two classic performance leaks that quietly stack into stutter. If you ignore both, you pay twice: GPU memory pressure plus CPU work the player never sees.
2025.11 - APV in Your Game? (Adaptative Probe Volumes)
APV in Your Game? (Adaptative Probe Volumes): If your indirect lighting workflow still depends on fragile manual probe setups, you are carrying a hidden bottleneck in both performance and iteration speed. One layout change and the relight cycle becomes a production hitch.
GPU Reality Check - Radeon GPU Profiler for Unity Pipelines
Know if you’re CPU‑ or GPU‑bound, see pipeline state changes, and separate work from wait before you touch a single shader.
Player‑Side Smoothness in Unity: CapFrameX + PresentMon Percentiles & Overlays
Judge ‘feel’ with data. Percentiles reveal stutter risk; overlays connect numbers to on‑screen actions.
Superluminal for Unity, Fast Hot-Path Hunting with Filters & Histograms
Sampling is only half the story, Superluminal makes it navigable. Filter by your scripts, expand the hot path, and act fast.
Sampling vs Instrumentation in Unity, Field Ops with Very Sleepy
When the Editor profiler isn’t enough, sampling profilers expose engine and script hot paths from your actual build.
