As Hotham's renderer is primarily memory bandwidth bound on the Quest 2, dropping to 16 bit data types will not only improve bandwidth, but in general only use a single instruction, compared to two, when operating on them. This could be a very significant performance increase.
TODO
[ ] Modify Vertex struct
[ ] Modify asset importer to convert to the correct precision
