NOTE Due to an issue found (thanks to player feedback!) we have disabled 64-bit support on Preview. Once we have resolved the issue, we will re-enable it on preview and notify the community.
We have re-enabled support for 64-bit on our Preview servers and are looking for feedback on its performance. Starting TODAY please log into the Preview server and let us know if you experienced any issues starting the game client or with data files.
Note: If your computer OS is 64-bit, you will be on x64 by default. Please do not check "Use 32-bit Client" on the Options Menu when testing out x64.
