I am making a car game which currently has three sprites: the background, moving road lines, and the car. If I draw just the road lines and the car, and not the background, everything runs smooth. But when I draw the background, everythings starts to lag. I did a check, and it only loops through the main game loop 10 times per second when the background is drawn, but around 100 when it's not. Just simply commenting out App.Draw(Background); fixes the problem, but this is of course not an option. The background is a 800x600 .png file. Anyone has an idea why this is happening? Thanks in advance.
