Unreal Engine 5.3.2 Still image renderings quite blurry using path tracer

Hello, I recently started to use Unreal Engine, created scenery and everything to my likings, sorted all materials and textures, but when I got to rendering point, everything went downhill. I used rendering settings my friend gave me who is creating high quality architecture visualizations. With those settings, he is getting good, sharp images. I used the same, it feels like whole pictures has soft blur and is out of focus when you zoom in a little. I tried many different ways, did not work. If I use default Unreal high resolution rendering settings, image is way better and sharper. Feels like there is issue with path tracer, but I’m unable to locate that issue!

You would need to share before and after images, as well as your settings if you need more help. You need different settings in different environments to compensate and get great images.

Here are my rendering settings and output with settings I used.
