Background/reference image looks blurry (viewport) - settings?

[KenTea]

Hi. Thank you.

• Yes, i have already disabled everything in Edit > Preferences > Viewport settings. Strangely, the Quality and Texture settings do not affect the reference image at all. I saw some effects on objects and wireframes but not the image.

I found some clues but it looks like it is an issue with Blender.

• I took a closer look of the image in Blender and it looks like the issue is indeed some filter because the image looks anti-aliased and not as if it was missing image information.
• So i went back in Maya (remember that in Maya i had to change several different settings). After some testing i identified the setting that gives the same result as Blender. It is a texture filter setting with the options: Off / Mip Map / Box / Quadratic / Quartic / Gaussian. The setting to keep the image unaltered is of course Off.
• But i recognise these filters. I read about them yesterday in Blender discussions while researching the issue. Where can i find them now?

For example where i can find this option in the latest version?

- YouTube

or how can i do this for a reference image (second post)?

2.8 where is Mipmaps option for working with pixel art

I know in the current version of Blender 2.79 the option to disable Mipmaps is under user preferences/System/OpenGL. In 2.8 this option seams to be gone or moved, so my question is where to? Im working on lowpoly with pixel-art textures at the moment so it would be great to have crisp pixels.
