Blurriness when rendering in parallel projection

I have been trying to render my model in parallel projection but it appears blurry half way through. I have disabled D5 SR and updated my NVIDIA graphics driver but so far I have not been able to resolve the issue. When I render in perspective view the model appears at the right resolution. I have saved the two renders in parallel projection and in perspective view both rendered at 4K quality here: Unique Download Link | WeTransfer

In parrallel projection details appear like this:

Whereas in perspective view details appear sharp:

Is there any way I can achieve the same level of detail in parallel projection view?

Hi @am3424

I tested the same setup using the Residence Lawn demo scene (Parallel Projection at 4K), and it renders normally without any blurriness.

To help narrow it down, could you clarify:

  1. Does the blur appear in the viewport preview or only in the final render?
  2. Is it happening in all Parallel Projection views or only certain angles?
  3. Does it still occur in a new empty scene with a simple model?
