My suspicion is data transfer from the system memory (dsplBuff) to gpu
is not a DMA.
Probably not.
So, what other efficient methods are there?
Do you know how can I improve this?
I would send it as unsigned char, not int. Your graphics
card is going to convert it anyway so you can cut out the
data conversion (converting it yourself as you receive it
is bound to be more efficien than making the driver do it).
