very slow light scene calculation

i imported ifc model of my steel beam building (2000 m2), rather simple model, but calculation for separate rooms is so annoyingly long.

I even chose to calculate only active lighting scene but it takes like 40 -50 minutes for room 12 sq. meters. Looks like dialux is always calculating all scenes even if i chose only active lighting scene.

Is it possible to do something to get faster calculation of lighting scenes?
