I have a new pc and does the picture always blur?

I have a problem on my new pc I have installed minecraft but when I move into Minecraft everything blurs, e.g. With signs when I walk towards it, the font blurs. Does anyone know what I can do? Here graphic settings pictures:

You might be. (If not already done) Install Optifine or use another texture pack. You could also press F3+ a. That reloads all chunks. Or the shader on off. If all of that doesn't work, I can't help you.

Something like motion blur should be deactivated

Although with your number of hours of play you already know all this…

Change your shader from "Internal" to "Off"

Maybe it's because.
