ubo slot

EDIT: The memory you can bind to an UBO slot can be as low as 16kB actually. 64kB is a common limit, but not the one that the spec defines as minimum. I recall one Intel forum post that asked why in D3D11 you can have 64kB for a constant buffer but in OpenGL you only had 16kB, only then the Intel driver team incremented the limit to 32kB. fifa 99 slot
