Could anyone give me feedback on download times for textures on an Onyx2, iR system?
I have a 3D-texture (128x128x128) which
I update for every frame (128x128x90 in size) with glTexSubImage3DEXT(). Modulating rendering parameters gives an estimate of a download time of 50 ms. The texture is only
2 or 1 byte in cell-size, giving a total size of 2.8 or 1.4 MB. The data is loaded in a separate thread, so loading time from disk to memory is not the issue.
