The invention discloses a method for dynamically adjusting picture processing performance, and further discloses a display terminal. The method is applied to electronic equipment with a multi-core graphic processing unit (GPU), and comprises the steps that when an application is started, identification information corresponding to the application is acquired; the number of GPU cores corresponding to the identification information is acquired; whether the number of the GPU cores corresponding to the identification information is consistent with the number of GPU cores adopted before the application is started or not is judged; if the judgment result indicates that the number of the GPU cores corresponding to the identification information is consistent with the number of the GPU cores adopted before the application is started, the application continues operating, otherwise, a first drive file, corresponding to the identification information, of the GPU cores is loaded. The method and the display terminal can reduce power consumption, save resources and improve working stability.
