The American international is yet to score in the Premier League following his £6million summer switch from AZ Alkmaar.
But the former Hull City man is confident that he will soon find his form at the Stadium of Light.
"Any player is a product of the environment. If we're playing good attacking football, you're always going to have opportunities to score goals," Altidore, who is currently on international duty with USA, said.
"I don't change my mentality or the way I play.
"I feel like I'm playing well at Sunderland. We just have some bad luck right now, but I feel like I'm playing well and doing things right."
Altidore has acknowledged the importance of the club's short-term goal of avoiding relegation, but also insists there is a bigger picture that needs to be looked at.
He told The Journal: "I think it kind of stunts when you are trying to build something because of the pressure of staying in the league.
"Every year, there are different types of teams in the Premier League just trying to stay up.
"If we can just focus on building a good team and try to leave the rest of the stuff out, it will be good for us. Hopefully the new manager can help us do that."
