Hi Desperado,
With the limited information on this question and assuming this as a duplicate request for your earlier post, I guess you are asking about different ways to upload texture to GPU without having a driver side copy. This thread here 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
