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.
Great 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 isn’t “just a graph.”
I built a custom RDG compute pass in Unreal Engine, broke SceneColor, got black frames, and finally understood why RDG exists.

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.
Deep dive on how Unreal actually generates them 👇

Between vertex factories, static params, and Unreal’s compilation model,
shader permutations become invisible technical debt.
I did a deep dive into how Unreal actually generates shader permutations — and why the cost stays hidden.

A few questions worth asking:
• How many permutations does your “simple” master material generate?
• Are static switches necessary — or just convenient?
• How many permutations come from usage flags you enabled once and forgot?

Ran the FAB Warehouse Environment on a modest RTX 3050 laptop at first, 18 FPS. Brutal.
After profiling & cleanup: 44 FPS.
Here’s what worked: medium.com/@GroundZer0/af858…

Global Illumination isn’t just about light quality — it’s about how much GPU you can spend to keep it dynamic.

Nanite performance isn’t just about triangles , it’s about how clusters stream and how you manage budgets.
Push too many high-cost clusters, and streaming becomes the real bottleneck.

LOD chains are dead.
But your job as an asset author didn’t vanish — it shifted.
Here’s how to build Nanite-ready assets that actually scale 👇

Nanite loves triangles. It hates your materials.
Here’s why performance tanks (and how to fix it):

Nanite isn’t magic , but it’s one of the smartest geometry systems in game dev. 🎮
My first deep dive covers what it is, how it works, & why it matters.
