I noticed that my Sony Vaio notebook is equipped with a NVIDEA GeForce 7400 card. As this type belongs to the 7 series ( see the specs) I have downloaded to corresponding SDK and made some checks. It seems that most of the demonstration software runs (those programs which are not running are relying on Direct3D I guess).
Thus,I have started to write some small piece of code which uploads some demo data to the texture buffer, tries to manipulate it somehow and writes it back to CPU memory. My first impression is that coding might be not such a big issue, but getting your piece of source code compiled might be somewhat tricky.
