After watching one of the most dramatic finishes ever at the recently completed Ryder Cup, South African Charl Schwartzel says changes are needed if the Presidents Cup is to ever experience such passion.

The Ryder Cup, which is steeped in tradition and pits the best golfers from Europe against the might of the United States, has become a highlight on the golfing calendar for both players and fans.

In this year's edition, the US led 10-6 heading into the final day before an Ian Poulter-inspired Europe came storming home to retain the trophy 14.5-13.5.

The Presidents Cup, which is held biennially and matches an International team - minus Europe - against the US, struggles to raise the same level of hype and excitement as the Ryder Cup.

The International team has only won the Presidents Cup once since its inception in 1994, with the US securing seven triumphs in what Schwartzel said had become a predictable tournament.

"I think there's a few things that might have to be changed in the Presidents Cup to make it that special," said Schwartzel, who made his Presidents Cup debut in the Internationals' losing side of 2011 at Royal Melbourne Golf Club.

"The Internationals need to start ... winning a little bit more.

"At this stage, the Americans have just won so many that it's just assumed and it sort of makes it die out a little bit.

"There needs to be a format where the Internationals can be a little bit stronger.

"I think the American side, every time they play, their world ranking hardly ever goes past 20th, whereas the International No.12 player sometimes is 60th in the world.

"So they are definitely still stronger. There needs to be a way to make it more even. I think we need to have that sort of competition and it will make it very exciting."

Schwartzel, who won the 2011 US Masters, will be one of the favourites when he competes at this week's $2 million Perth International at Lake Karrinyup starting on Thursday.
