Why is it when I zoom at any value other than 25%, 50% or 100% my photoshop image looks pixelated?

Question

This is really bugging me and I can't get any work done...but I've had Photoshop for years so I know that if you zoom at any value other that 25%, 50%, 100%, 200% etc then the image loses some of it's quality, but up until today the image looked a little blurry when at a different zoom value, but now it looks really pixelated which makes the image looks really ugly and is making it hard to actually do anything. I have no idea what I did to change it to this, but now I can't change it back and I've tried everything I can think of.

I've been using Photoshop for a decade and a half and have never, ever seen what you describe.
