120%. My vision is technically good enough to not legally require glasses, but astigmatism makes it a little squinty to try to read the forum without a touch of magnification.

(120% firefox, 1920x1080, 15", 125% recommended win scaling)

OK, well if you ever get a high res monitor you may find it desirable. I scale everything to 150% and find the GOG forum to be OK.

Just upgraded from 60 hz to 240, don't plan to upgrade soon.

Dang, didn't mean to lord over with my clear vision. I myself had trouble seeing projections in school, so I can see the need for assisted tools for legibility's sake. I figured I'd only mention that stuff since I have no trouble with the default layout.

4k.
No zoom.
RAW.

I'm hip to your lingo.

My zoom is anything that's happening, man. Anything that ain't square.

1080p, 27 inch screen, 110% zoom

On what, a 500 in Jumbotron?

I'm so hip I have trouble seeing over my pelvis.

120% zoom, 1080p, 22".

27", 1440p, 100% scale, 100% zoom.
What about Windows scale and screen size?

130% at 1920 x 1080.

32".

I have 20/20 vision, maybe that's why it's fine for me. I dunno. I read everything just fine.

Inside Firefox I don't use zoom, but in the whole of Windows my 1920x1080 monitor is zoomed to 175%. The older I get (52 and counting, it only counts up, never down), the more my eyesight worsens, but I find it too cumbersome to use separate midrange glasses for screen or reading glasses for books. So zooming in Windows to watch the screen and putting my -8.00 glasses more to the front of my nose for reading instead of using separate glasses is my workaround.
