PGA TOUR 2K23

I did this achievement in the "Casual" play mode ( to move on the home screen, between "Competitive" and "Topgolf"), then "Local Match". Be sure to change your golfer from the MyCareer/MyPlayer option. While hovering over your gamertag, you should see a "Change Golfer" option above your highlighted box. Tiger Woods should be the first one on the list, so press A on his name.

Then back out of the Golfer Select list, and on the right choose a course. You can select any of the "Recommended" courses, as they should all be 18 holes, or use the "More Filters" to find an "Easiest" course. Be careful with this route, as you may see some user-created courses that aren't actually "Easiest" that could be a huge pain to complete.

Make sure you have "Stroke Play" and "Full Course" selected, then click "Begin Round".

Simply play the entire course through to the end while scoring at Par or Below. This is very easy with all the control settings set to the simplest/easiest they can be. I ended the round with a score of -8, and somehow even got the "Peak Performance" achievement where I activated 5 different skills in a single 18 hole round. No clue how i did that, so i can't explain why that popped too. Just something to keep in mind if you haven't gotten that one yet.

The achievement will pop as soon as you get to the "Results" screen for the course.
