I'm aware that geometry shaders are required to load many graphics on many games. I am also aware that work is being done on documentation regarding the implementation of geometry shaders.
My main question is: Are graphical effects the only importance of geometry shaders. Or does having them allow performance boosts, in say games like monster hunter or other capcom games that make heavy use of geometry shaders? Thanks for any information that can be given. I've just been curious about this.
