Optimizing the Eevee rendering engine

[★Krako★]

Hi, could someone in the community explain how I can optimize the Evee rendering engine? I have no problems with Cycles, and it's the one I usually use, but some models look much better with Eevee.

I need to know the most optimal configuration to use without causing crashes or lag, much less affecting my CPU

if you’re seeing lag or CPU spikes in Eevee, first thing—double check that your shadows and screen space settings aren’t maxed out for no reason. here’s a quick checklist you should reference:

Turn off Bloom, Ambient Occlusion, and SSR unless you really need them—these can tank performance

Lower the Shadow Cube Size / Cascade Size in render settings, 4K shadows look nice but fry your PC

Clamp the samples / 16-32 is usually enough for viewport

Make sure volumetrics are minimal or off unless it’s a key part of your scene

Try switching "Soft Shadows" off if your shadows look fine without them

Under Performance, check "High Quality Normals" only if you need 'em

also Eevee is GPU-heavy, so if your CPU is getting hit hard, it might be from other background stuff, or you’re accidentally baking something you shouldn’t. keep task manager open and see what’s eating cycles.

let me know what you’re trying to render and I can probs help tune it better
