Armory with Voxel is too slow

I played the templates, what i figured out is Armory 3D is too slow when using voxel ao or gi on a 1080p resolution, for semi realistic looking game.

While the fps template , same settings Voxel AO, deactivating bloom and motion blurr, it runs smoothly. Or the toon shading template with grass runs fine in 1080p.

Will there be some improvments regarding graphics performance ?
Or it is some issues with the third person template ?
