ive seen it as a big thing for mods and the game having more pbr and i under stand it is better graphics things but that is where my understanding of it ends
Physically Based Rendering, basically it is a way of rendering materials that more accurately emulates how materials are in real life, using properties such as Metallic (is it a metal or not) and Roughness (is it shiny or not shiny/matte) which as a result has the power to yield more accurate, or 'better' looking graphics for games lmao
