Hi Desperado,

With the limited information on this question and assuming this as a duplicate request for your earlier [post](https://forums.imgtec.com/t/memory-leak-using-gltexsubimage2d/3683/2), I guess you are asking about different ways to upload texture to GPU without having a driver side copy. This thread [here](https://forums.imgtec.com/t/understanding-pbo-texture-uploads/2358) from the past discusses and lays out some good information on this topic that could be of some help.

If you could provide us more information about the specific case & simple glTex\*Image2D code snippet then it would help to better serve your queries.

Best Regards,  
Nagnath
