it depends on which flavour linux, i can get it to run on debian. i haven't a clue what an emulator overhead is ? wine runs apophysis with practically no difference in peformance, x-windows has sometimes a bit of a problem catching up, some redraw flicker, i have other problems, ie have corrupted the my flmes flame file, mind you it was a bit big, ca one gig i think my husband said. i have no idea what kind of problems you my run into using uf because i don't use uf, and, my windows platform is win 98, i don't reackon much to any windows distro after win98 (i think they're all rubbish)
