Textures and models go from smooth and anti-aliased in 1.40.67223 to jagged and blurry in any version after.
Here are screenshots of all the aliens you meet that have a 3D model in-game...
Some differences are minor, like the tetxures are blurred here and there, but other differences are massive, like the Tywom homeplanet representative being jagged and messy everywhere.
What I do is open a race's image for each version in a new instance of Chrome and hit Ctrl+TAB to flip through them quickly so I can see the differences.
Recently Schism Navigator has been saying it was a driver issue but I've ruled that out by using various older drivers going back to when Origins was released but with the same results.
