Flickering-picture included

Jeese, what do you guys do to avoid flickering - tried denoising, but it doesnt help.
I use NO textures, my scene consists of a town (see attached picture)
the fine lines around the windows + the roofs flicker… I ve checked for doubles, but can´t find any.
Im looking for a workaround - somehow - wondering whether I should remove the finely modelled windows and tile roofs and subsitute them with a simple texture that imitatates the windows… but the fine lines would till remain though…
any suggestions as to what to do?
I render in cycles, 300 samples

Hello. Could you provide a video or a blend of the flickering?

thank you for your answer! Its a very huge file, I´ll try to shrink it so I can upload either the video file or the blender file or both.
