直接在屏幕上写文字 - 退出之后没有清除，sorry 演示了3D文字和任意形状的窗口，由于CPU占用率太高，后来就改成直接写在屏幕上，而不显示窗口的做法。这样一来CPU占用就不会超过10%-directly in the written text on the screen-not after the withdrawal of removal, sorry demonstration of the 3D characters and arbitrary shape of the window, as CPU utilization rate is too high, and later on changed to write directly on the screen, with no sign of the window. Such a CPU utilization will not exceed 10%
