64 bit windows build

Post by abma »

Current development version is build for win64, too. The first build can be downloaded from the buildbot dir:

http://springrts.com/dl/buildbot/defaul ... 713/win64/

api.springfiles.com / pr-downloader (should) support it already, hopefully springlobby and other lobbies will follow.

http://api.springfiles.com/?category=engine_windows64

A lot of thanks to hokomoko and TurBoss who spent a lot of time making it work!


As a result of this work, mingwlibs for 64 bit were created: https://github.com/spring/mingwlibs64

very likely they will only work with the same compiler (gcc 4.9.3)

Note that if your system is 64 bit, it doesn't necessarily mean the 64 bit version will run faster on it.

What is the main advantage here, more access to physical memory? That would be helpful if spring were to ever use over 1gb anyway :-D That said it's awesome that it's more "future proof" in this way.

tl;dr
Yay!

i guess thats the only real advantage here. it seems the 64 bit build is slower as the 32 bit build because of more memory usage / fewer cache hits.

Is this speed difference theoretical or tangible?

needs benchmark(s). i would expect a slowdown of ~5%, but thats just a wild guess.
