The rendering speed element serves to find out the value of the rendering speed, i.e. the speed of the 3D graphics painting. The rendering speed is expressed as the number of frames per second. The resulting data is rounded to an integer. Withal the measurement runs at a higher accuracy using data filtration and stabilization during the time period of several frames. The data can be used to automatically correct the rendering quality, when the speed is too low, or, on the other side, too high. When using this data one must take into consideration that the data will get stabilized only after several frames have run off.
