You were mislead. Options to enable/disable 3D acceleration are long gone, and were never available on Win10.
Are you using an old disk based version or a current download ? I would be surprised there would be any issues with
Win10 when using the current updated Terraria, but I guess the core of the game hasn't changed ?
You probably need to enable Direct Play in ...
Programs and Features > Turn Windows Features On or Off.
Enable Legacy Features and Direct Play.
( An great example of MS's short-sightedness, not having these options on by default. Particularly in view of
MS promoting Win10 as 'the best gaming Windows ever'.
Locked away in the rarefied atmosphere of the MS Ivory Tower, they don't seem to realise how many people still play old games. )
