I was very disappointed when one of my favourite fractal generators, Fractint, was not behaving nicely after I moved to Windows XP. No matter what I did, it refused to work. It sometimes barely worked in very low resolutions or something, but it used to lock up not too much after a few things were done.
After some Google searches (I’m not even sure if Google was so good in helping fixing things back then) I learned that it was because mostly of the lack of support for VESA graphic drivers starting with XP. What could I do? Nothing, or else try to use it with these low resolutions or these odd IBM presets (that somehow didn’t use the VESA I think, some of the presets at least) or the mysterious and unpredictable “render to disk” feature of Fractint.
