Cotter still not happy
Scotland controlled the match from the start in front of a record crowd for a World Cup warm-up at the home of Scottish rugby
Wings Sean Lamont and Tim Visser each scored two tries, the others coming from flank John Barclay, who was making his first international start for two years, and centre Mark Bennett.
However, Scotland coach Cotter was reluctant to shower praise on his side.
"Three tries came from interceptions, so we'll have to face the reality on that. We weren't particularly accurate at times," Cotter told AFP.
"I'm not entirely happy with everything. We're improving but there's certainly a lot more to be done. We need to step it up again," added the New Zealander, due to name his World Cup squad on Tuesday.
Scotland captain Greig Laidlaw – who kicked two conversions and four penalties – was more fulsome in his praise.
"We're delighted that we put them under pressure for such long periods of the game," said the Gloucester scrumhalf.
Laidlaw singled out his halfback partner, Finn Russell, who had an outstanding game orchestrating Scotland's attack with perception and precision.
"Finn's a wonderful talent," said Laidlaw. "I thought he had a wonderful performance today. Hopefully that can continue next week and into the World Cup."
Scotland play their final warm-up match against France in Paris next Saturday and open their World Cup campaign against Japan at Kingsholm in Gloucester on September 23.
