Quick answer: Construct 3 particles not spawning on low-end Android devices? The engine throttles when minimum framerate drops - check Particle minimum_framerate and disable auto-throttle.

VFX-heavy boss fight: PC players see hundreds of particles; older Androids see zero.

Disable framerate throttle

Particles property > Minimum FPS = 0. Default is 30; below this, the engine skips spawn ticks. Better to drop quality than to stop spawning entirely.

Or reduce particle count

Halve spawn rate for low-end devices via runtime branch. Visible particles; consistent performance.

Profile per-device

Construct 3's debugger over USB on Android shows actual frame rate. The throttle decision is visible; tuning becomes precise.

“Particle systems auto-throttle. Auto-throttle to zero is a configurable choice.”

Maintain a 'device tier' setting in your game. Tier 1 = full VFX; Tier 3 = minimal. Tested per tier; players never see the worst case.
