Team Fortress 2 - mat_phong Visuals

Comparison between settings 'mat_phong 0' and 'mat_phong 1' on each class with a close proximity light source. By default, TF2 will boot on mat_phong 1. This can be temporarily changed by entering "mat_phong 0" into the developer's console, or permanently, by accessing Local Disk / Program Files (x#) / Steam / Steamapps / common / Team Fortress 2 / cfg / autoexec.cfg.txt / Enter "mat_phong 0" / Save the document. Alternatively: Right-click Team Fortress 2 in your Steam Library / Properties / General / Set Launch Options / Enter "+mat_phong 0". This method may, however, require calibrating your video options per launch. Rocket Jump Waltz Extended - https://www.youtube.com/watch?v=AtfRhG18AQw
