SoftMac breaking speed limits on 64-bit Windows May 18 Inspired by the recent release of 64-bit Windows XP Pro which I've now installed on my Athlon64 system at home, I tried running various release of Gemulator and SoftMac on it. To my surprise, it didn't work. Grrrrr. I took the most recent beta build of SoftMac 9.0 (a.k.a. SoftMac Pro) out of mothballs and debugged the problem. Turns out to be a bug on my part, making some incorrect assumptions which break on the 64-bit platform. My bad. After fixing the problems and tweaking a few performance issues (remember, SoftMac was last tuned for the Pentium 4 processor, well before the release of any 64-bit AMD or Intel processors) I gave the newly fixed SoftMac build a whirl under 64-bit Windows. Surprise! It runs faster than ever. This little $700 Athlon 64 box SCREAMS now running Mac OS. Attached is a screen shot, showing the performance pretty much beating all but the most top end systems from last year. Now, this really was just an experiement and I have no intention of resuming work on SoftMac any time soon. So for the time being I apologize that the SoftMac on our web site is broken on 64-bit machines. If enough people email me to tell me they're running Windows XP 64-bit and need SoftMac support, I might tear myself away from the movies.
