World Space UI low Quality

I am using a world space canvas for applying text on a card game I am making. however, the text is super low quality and hard to read.

now I've already dug around and tried a bunch of solutions and in the editor, the text is amazing quality but in-game it continues to look awful.

camera

Projection: Orthographic

size: 6-12 (player can zoom)

everything else: default

canvas

render mode: world space

dynamic pixels per unit: 100

width and height: 1000

scale X and Y: 0.001

Text

font: ariel

font-size: 300

things I have tried

distance from the camera (nothing)

change projection (nothing but when closer it became clearer)

anti- aliasing (worse)

dynamic pixels per unit (1, 10, 50, 100, 300, 1000, 10000. better in the editor but nothing in-game)

scale and width (1000x1000 width/height 0.001x0.001 scale. 1x1 scale 1x1 width. nothing )

also doing a build has no effect on quality.

I'm kind of out of things to try, and there doesn't seem to be many with the same problem (whos problem wasn't fixed with pixels per unit) any help would be appreciated, cheers.
