VXGI is out of the question for me for archviz and for portfolio images, not a single chance!
And I like to be able to record flicker-free 60 fps movies in high-res. You’ll never achieve that with VXGi. There is always a flicker or a shadow pop here and there.
The main problem in OP’s images is the ceiling. It’s unrealistically bright. There are no nuances in the lighting! That’s the main problem of vxgi, it’s not precise enough even when you crank everything up!
