The tournament - held at the same time as the prestigious WGC Bridgestone Invitational - is the only one on the PGA Tour to use a Modified Stableford format, which allocates points based on the number of strokes taken at each hole.
Eight points are awarded for an albatross, five for an eagle, two for a birdie, zero for a par, minus one for a bogey and minus three for a double bogey or worse.
Last year JJ Henry won the event with 43 points and, unsurprisingly, is a fan of the format which the tournament switched to in 2012.
"I really love the Stableford format," Henry said. "Last year was exciting. It was a neat finish coming down the stretch. When I first heard the switch, I know I can speak for a lot of players, we were excited.
"It's the only one on tour. That and (the two or three opportunities to play) match play, guys like change. And the golf course is a perfect fit. There's a lot of risk-reward. It's a fun format on a unique golf course."
Prior to the 2012 Reno-Tahoe Open the Modified Stableford format was last used on the PGA Tour in 2006 at The International, but the Tour supported the decision to make the change.
"The PGA Tour believes there is merit to this format for Reno," PGA Tour vice-president and chief of operations Andy Pazder said. "The Modified Stableford system not only promotes aggressive play, which the tournament is already known for, but Montreux lends itself well to this exciting format with its series of challenging finishing holes."
Henry returns to defend his title in a field which also features three-time major winner Padraig Harrington and Scotland's Russell Knox, who shot a second round of 59 on the Web.com Tour last week.
Harrington faces an important two weeks as he tries to secure his FedEx Cup play-off place. He currently lies 123rd in the standings with the top 125 to qualify after next week's US PGA Championship.
