I think then, computing mipmaps for any texture file on the CPU in the loader thread should globally improove the situation. Also avoiding the compression already in the files should help every use case. Except that the on disk memory consumption is higher. Well and except that the database loader has more work to do on the CPU. Mathias ------------------------------------------------------------------------------ Ridiculously easy VDI.
