Skybox - HDRI Pictures how to?

Hello there. Id have a question about HDRI skyboxes. Im always trying to insert a proper one but it either is too large, too small or unsharp ( im using 8k quality HDRIs from the recommended websites from Enscape) So what am I doing wrong with HDRI skyboxes what kind of pre-set up do I require to make work with it at all?

@Kristof95 , right away, if the 8k HDRI’s you are using are blurry, then that is usually because your GPU is running out of available VRAM while trying to display the skybox and project at the same time. It should help use a HDRI’s with 4k resolution instead, and/or via reducing the project/projects textures in complexity/resolution.

Alongside it simply depends on the scene itself regarding which HDRI background you want to use - Highly actually given that it’s not possible to simply resize an already captured HDRI afterward.

Feel free to also send me a screenshot of this behavior if trying to above does not make any difference.
