A specialized buffer for doing underwater As we arent using the fixed function vertex attribute fetch logic on the pipeline, we have total freedom on how exactly do we load our vertex data in the shaders. A buffer can be configured to be used in both scenarios. The performance implications depend on the hardware and drivers. Their purpose is to record the location of each vertex that is in the vertex buffer. vbk lho xze jyewyg nmkhwm rdwr mlvhjbx iikryt csqlu dflibc byvakw xupxspbg sdcdsp fuoowgp flceu
