...-details/problems of other people. So my proposition merly is to use more than one "upload-window". When you know how things work "under the hood" it is often nicer to do it yourself. I share that opinion. Unfortunately I still know too little about directx. What do you mean by more than one upload window? You would ensure that there is not just one texture upload every frame, or?

"John Withe": The way I do it now is to have a lot of memory (64 bit system) and store the data in a huge 2d array. I only have a single texture to which I copy. That should not be a problem as far as I can see? That is a problem, and one of the most frequently discussed topics here. Gruss Jan Bruns
