Maximum OVO and OPO in OpenGL

Please tell us about some of the limitations of OpenGL 4.0:

1) What can be the maximum size of FBOs?

2) What is the maximum PBO size I can create?

Thanks!

The maximum value depends on the amount of RAM + video memory that you have (and the complexity of each object). The graphics driver will determine the most efficient place to store VBO / PBO, whether in your RAM or your video memory.

Basically, you can create as many VBO / PBO as you want if you have some memory left.

the OpenGL specification does not seem to indicate any specific value, so I believe that memory is the only limit.

You will find out when you click glGetError() == GL_OUT_OF_MEMORY .
