This has come up again with the new "...Ethan Carter" game. It has been suggested that some might be helped if they disable "Anti Aliasing." I have always wondered what that is and what it does.

It gets rid of "the jaggies."
If your monitor has high enough resolution (and you're playing at high enough resolution), it doesn't make much difference. Here's a picture without and with antialiasing:

Another picture, where the difference is more obvious:

Thanks The Haze for that question and Jenny100 for that answer. I've wondered also.

Good explanation!

Thank You, Jenny100
