You can test Twin motion which is specialised with architecture but is beautyfull for small rendering.
It use GPU for realtime render as good as fps games. So no photorealism but very impressive.
It's a Unreal engine based software.

If you want photorealism, you can use Owlet render.
Not easy to find now, because editor's page says "Deprecated software".
A free version existed. Perhaps it could be found somewhere else...
