That's what I meant. You could have believed me in the first place, you knowsatiropan wrote:so in the end I loaded pictures of space from hubblesite.org, 67mb, 40mb and 27mb.
You were right, the board uses only 128MB of video ram, I get maximum 87mb of used video ram, and the normal ram is filled a lot, I reached having only 9mb of free ram, then,if I load another picture, the system locks.
Video memory is pretty volatile. Once it is needed, existing bitmap data might be cast out. Now, copying FROM video memory is mostly much slower than copying TO video memory, so the data is always kept in main memory and copied to video memory only for displaying.Set aside this question, why the system prefers to fill normal ram instead of video ram when loading pictures?
