The invention provides an animation performance detection method. The method comprises the steps of obtaining a quantity of to-be-detected animations in an animation playing stage; obtaining a maximum same-screen quantity of the animations according to the quantity of the animations; and obtaining a local minimum passed same-screen quantity of the to-be-detected animations, comparing the maximum same-screen quantity of the animations with the local minimum passed same-screen quantity of the animations, and if the maximum same-screen quantity of the animations reaches the local minimum passed same-screen quantity of the animations, indicating that the detection of the to-be-detected animations is passed, otherwise, indicating that the detection is not passed. According to the method, the animation performance is represented by the maximum same-screen quantity of the animations; the maximum same-screen quantity of the to-be-detected animations is obtained according to the quantity of the to-be-detected animations; and when the maximum same-screen quantity of the to-be-detected animations reaches the local minimum passed same-screen quantity of the to-be-detected animations, the detection of the animation performance is passed, so that the animation performance can be quickly and accurately detected. In addition, the invention provides an animation performance detection system.
