3D Visualizer System Requirements

The DMXDesktop 3D Visualizer renders your rig live as you program. It scales from a backup laptop to a dedicated workstation through two simple controls: a Quality preset (Low / Medium / High) and a Shadows toggle.

Visualizer quality only affects the on-screen preview. Your DMX output to real fixtures is unaffected - you can pick any preset, or close the visualizer entirely, and the show keeps running.

Quality presets

Low - keeps the visualizer smooth on integrated graphics, older laptops, or modest hardware. Edges look slightly jaggy and beams a touch faceted. Use this if you see stutter or hear the fan working hard.

Medium (default) - sharp on Retina and 4K displays, with smooth edges and standard beam detail. Tuned for typical modern laptops with a discrete GPU. The right starting point for most users.

High - 60 fps target, smoother beams, tighter ground impacts, and shadows on by default. Pick this if you have a discrete GPU and you want the cleanest look during programming sessions.

Quality settings save per-layout, so a programming layout can run on High while a "lights-up at the venue" reference layout uses Low. Changes are instant - no restart required.

Shadows

Shadows are a separate on/off switch that works alongside any preset. With shadows on, beams visibly cut around trusses, stage objects, and walls. The look is dramatic and reads well in promo screenshots, but the cost is real - shadows can reduce frame rate by 30-50% on weaker GPUs.

Leave shadows off if you're already at the visualizer's frame limit. Turn them on when you have GPU headroom and want the polished look.

Suggested machines

Low preset - integrated graphics, 8 GB RAM, any modern CPU. Best suited to older laptops, backup machines, or venue laptops that need to last a long evening.

Medium preset - discrete GPU with 4 GB VRAM, 16 GB RAM, 6-core CPU. Best suited to most users programming a typical rig.

High preset with Shadows - discrete GPU with 6 GB+ VRAM (RTX 3060 / RX 6600 / Apple M2+), 16 GB RAM, 8-core CPU. Best suited to studio programming sessions and promotional screenshots.

Apple silicon punches above its weight thanks to unified memory and the Metal graphics stack. An M1 handles Medium comfortably, and M2 / M3 chips handle High with Shadows well even without a separate GPU.

Tips for under-spec'd machines

If you're at a venue on a lighter laptop and want to free up frame rate, drop the Quality preset to Low and turn Shadows off. That single change is enough to keep the visualizer responsive on integrated graphics.

If the visualizer is still struggling, you can close the visualizer window entirely. The DMX engine, programmer, and execute grid all keep running independently and your show output continues uninterrupted.

Visualizer quality never affects your show

This is worth saying twice. The visualizer is a preview. DMX output to your real fixtures is independent of the preview's frame rate, so picking a lower quality preset, disabling shadows, or even closing the visualizer never affects what arrives at the lights.
