I'm able to calculate Albrecht Niekamp's: "The_Miracle" (that uses Multifractal_10) with all the comments in it in the form he posted it on the [Fractint] list serve Oct 23, 2012 -- in VESA video mode 640 x 480 with DOS Fractint v 20.04.4 under WinXP SP3. The video chip built into the system board of my computer only supports VESA video mode: 640 x 480, and the DOS environment for Fractint is able to allow the calculation of his fractal using that video mode. However, when I try to use the 640 x 480 (or 4k x 3k) Disk Video modes, I get: "Insufficient memory to run fractal type 'formula'" Invoking Disk Video mode apparently allocates some additional memory that "breaks the camel's back" -- despite using the hard drive to write the image to. The version of Multifractal_10 *without* comments has this same problem. Here's Albrecht's "The Miracle" at 640 X 480: http://www.emarketingiseasy.com/TESTS/FOTD/T_MIRACL.GIF and a zoom into it: http://www.emarketingiseasy.com/TESTS/FOTD/T_MIRAC2.GIF Question: Any of the developers have any idea of how to get around the Disk Video modes not leaving enough memory for multifractalll-10 to run? Any debug modes lurking around that might help -- say, specifying the allocation of smaller Disk Video buffers? - Hal Lane ######################## # hallane@earthlink.net ########################
