Not rendering well using path tracer

So i've been using Twinmotion for a couple of days and almost everything besides a few things are going well. Like rendering with path tracer for example is doing some weird things, i've added a lot of pictures with different rendering settings:

(1. Low path tracer setting

2. Medium path tracer setting

3. High path tracer setting

4. High path tracer setting with denoiser off

5. Really high path tracer setting with denoiser turned off

6. Rendering with Lumen instead of path tracer)

I feel like I just have to turn a setting off or on but I can't find what. I would really like using path tracer for rendering because when I look at other renders it looks really good.
