64-bit Client Beta FAQ on the Guild Wars 2 Forums has details on testing
that's now underway on a 64-bit client for ArenaNet's MMORPG sequel (thanks
PCGamesN). This covers a lot of basics, as well as details on how to check
this out without a full reinstall and how this can peacefully coexist with the
32-bit client. Here are some relevant details:
Does the 64-bit client
only benefit players with more than 4 GB of system memory?
No. It is true that the 32-bit client in theory can access up to 4 GB of memory.
In practice however this is almost never the case, due to gaps in the address
space that slowly build up over time (known as fragmentation). Most players
crashing today due to being “out of memory” are actually only using between 3
and 3.5 GB of their system memory.
In addition to this, modern operating systems use something known as “virtual
memory” to extend the available memory beyond what the system has physically.
The 64-bit client will allow you to benefit from the increased address space by
making gaps largely irrelevant, and will allow the client to use more memory
than it could otherwise rather than crashing.
Are there any performance differences between the 64-bit and 32-bit client?
There may be some very slight differences in favor of either client depending on
your computer’s configuration. In the vast majority of cases it should be
Why is the 64-bit client using more memory than the 32-bit client?
Due to the technical differences between the two platforms the memory usage will
never be directly comparable.
Is there a 64-bit Mac client?
Unfortunately, a 64-bit Mac client is not available at this time. We are hoping
to be able to provide one in the future, but have no timeline to provide
Does anyone feel like it's a crying shame games were still being designed for 32-bit this many years later? We've had 64-bit CPU's since 2003. I understand why you would make 32-bit clients for games for maybe 4 years after the fact (5 tops), but after 2008, if you were making a game exclusively for PC, and you made a 32-bit client, you're a damn moron. And they say it's consoles that's holding back game development when in fact it's all the luddites.
The 64bit client make the game run much smoother for me, though I kept crashing when I tried to enter Fractals. Also, the 64bit client isn't recognized by Shadowplay so I can't see the FPS while playing (don't want to keep the options menu open to see framerate). However, the 32bit client reports 60-70 FPS in typical situations and around 25-30 during world boss events with dozens and dozens of players... so I would say the 64bit has roughly a +5%/+10% improvement.
Anyhow, the 64bit has great promise, but needs a lot of work.
