Is EqEmu 32 or 64 bit?

[Uleat]

Actually..many software developers still use 32-bit builds to save memory.

There aren't a lot of things out there that require more than 4 GB of addressable ram.

You can take code (such as EQEmu) and compile both versions of it.

the 64-bit will always have a larger footprint if for no other reason than the size of pointers.

Pointers are 4-bytes in 32-bit builds and 8-bytes in 64-bit builds.

There may be some small gain in performance by using 64-bit pointers due to using 'native size' ..
but, the real difference between size and performance is likely negligible and it really boils down to choice.
