One of the most important factors for the successful realization of a construction project is the use of advanced software in the field of architecture. Nowadays there are many different programs for visualization. It is increasingly used to help decision-makers make economically optimal decisions. However, lack of information about interconnection of these programs and computer components leads to incorrect use of the program as well as increasing of time spent for visualization. This paper describes a method of reducing the time spent for rendering a final scene by changing the clock frequency of the computer. The data that have been obtained show changes in the rendering time after using Overclocking process for different visualization programs.
