Iv been reading OPENGL distilled and trying the basics of a 2d OPENGL engine that i want to build. Iv been able to do it in the past with immediate mode, but that slow and eventually going away so im working with VA's and VBO's. I understand the concept of being put into either system/vram but how do i handle the memory management aspect? If i setup a system to create VBO's for all the 2d images i want to load, eventually i run out of vram right? How does one handle this situation. Or does OPENGL swap VBO's from vram to system ram on its own? Thanks for any guidance. I have very little knowledge of memory issues in game programming, just looking to learn how its handled.
