Using UE5's defaults? TSR, Lumen, and VSMs might be costing you more than you think.

These features aren't just "free upgrades" they're performance tradeoffs that assume high-end hardware.

Breakdown on what's actually happening under the hood:

TSR costing 3.3ms in a basic UE5 scene made me rethink AA entirely.

But for stylized / non-Nanite projects?
They can hurt clarity & performance.

RDG finally clicked for me when I broke it.

Built a custom RDG compute pass in Unreal Engine, hit SceneColor pitfalls, and learned why explicit read/write intent really matters. Here is how it went 👇

Building Lightweight Profiling & Visualization Tools in Unreal Using ImGui Unreal gives you a lot of profiling data, but staring at numbers rarely tells you where things actually go wrong. Most of the stats are…

Visualizing performance stats builds intuition faster than staring at numbers.

I experimented with building lightweight profiling & visualization tools in Unreal using ImGui.

Shader permutations in Unreal stay invisible
until compile times explode.
Static switches look clean
but silently multiply shaders.
