drawing without pixels - PLEASE HELP!

I have been using TBS 4.5 and have since upgraded to Animate 7.6. in 4.5 I was able to eliminate pixles (basically, no matter how far you zoom in, it’s a line, not blocks). I can’t figure out how to do this in 7.6, and I don’t even know what to call it. can anybody help???

Please check the Animate 2 “User Guide.pdf” page 83 onwards to get familiar with
Real Time Antialiasing and Full Scene Antialiasing…
Then adjust your system appropriately…
