Yeah... I just read some user feedback on
Versiontracker regarding Diablo II, and the performance of the Mac version is apparently pretty dismal. And it's coded for PowerPC, so it can only be worse on Intel Macs.
The GOOD news though is that I checked Codeweaver's database. The Windows version of Diablo II, though not expressly supported by Codeweavers, apparently works VERY WELL through Crossover, or at least it does through the Linux version. There's some current discussion about it still in their
Diablo II forum that sounds promising. I've started serving as an advocate for a few of my favorite older games... I may see what I can do with this one in the next few days.
If you don't know what Crossover is, it's a commercial version of WINE, which is a project that works on getting Windows apps to work under Linux (and now OS X for Intel) without an emulator running Windows. It has very little ipact on the system, and for what works well through it, it works VERY well and without the performance hit that solutions like Parallels and VMWare bring.
