Very pixelated preview in Photoshop

Hello!

I wanted to ask this question a while so here we go.

At my workplace my photoshop was working totally fine until i think around half a year ago (perhaps after an update?) my photoshop show a very pixelated version of the art i am working on. Only on 1-2 certain zoom percentage it looks okay, otherwise sometimes it very terrible. Working this way is very hard because i never able to see the artwork properly as i am working on details and always on a different zoomed-out or zoomed-in percentage.

At my home computer my photoshop works totally fine: at home every zoom percentage looks smooth and not pixelated. But at my workplace computer its sometimes unusable because of the pixelity...

Can anyone help me in solving this? I just can't work normally this way...

I tried changing things in the settings/performance already and it had no effect.

Thank you in advance!
