Weir captained the International Team in his native Canada last month and saw his side respond to losing the first session 5-0 by winning the second by the same scoreline, only to eventually suffer a seven-point defeat to the United States.
The 54-year-old has now turned his attention back to playing and is among the field for the inaugural Black Desert Championship, the first full-field PGA Tour event to be held in the Beehive State since the 1963 Utah Open Invitational.
"When you're the captain of a team like that, you put yourself aside and your game aside and you're focused on those 12 players," former Masters champion Weir said of his Presidents Cup experience.
"It's a big thing that weighs on your mind all the time. You want the experience to be great for everybody.
"It was a wonderful experience, except not winning. The main goal was trying to win.
"At the same time, now that that page is turned, now it's back to my game and I can focus on my game. I took a few days' rest and then when I got home, started working on my game.
"It was in a good place before I went to Montreal, I was off 10 or 12 days and it seems to have continued. My practice has been going well. Now I can just focus on trying to get in contention here."
World No.41 Chris Kirk is the top-ranked player in the field at Black Desert Golf Course, the last course designed by the late Tom Weiskopf.
Weiskopf, who won the Open Championship in 1973 and was runner-up in the Masters four times, died in August 2022.
