Create OpenGL object that always stays in GPU memory -


is there method create opengl object stays in gpu memory (texture or buffer)? opengl can unload objects ram memory. purpose fill gpu memory. example: have 1 gb gpu memory , app needs fill 512 mb of gpu memory.

is there method create opengl object, stay in gpu memory always

no.

also modern gpus have mmus , can fetch subsets of data in larger object.
