Would zdoom benefit from a 64bit version?

[iVoid]

Would there be a significant performance improvement? I'm thinking of maps that are very taxing even on modern computers, stuff like planisfere 2 or even nuts.wad. What stands on the way of doing such a version?

ZDoom runs in 64-bit just fine. The performance is roughly the same. The renderer gets a slight speed up from being able to render 8 columns simultaneously, but the larger pointer size probably slows things down equally elsewhere. Because of this, it makes no sense for us to distribute a 64-bit version for Windows or OS X. On Ubuntu, multi arch support is an optional feature that needs to be installed afterwards so 64-bit binaries are provided there. (Linux distros have been able to run exclusively 64-bit software for a few years now.)
