Star Wars: The Old Republic Upgrades to 64-Bit in Major Update

BioWare's free-to-play MMORPG Star Wars: The Old Republic has just released a major update that upgrades the game to a 64-bit client, a leap that has serious implications for the game's future in terms of performance and content. As usual, the update also includes plenty of balance changes as well as a rather controversial change to Star Wars: The Old Republic'seconomy.

Like most MMORPGs that last more than a decade, Star Wars: The Old Republic has been showing its age in recent years despite many overhauls and improvements. Most recently, SWTOR's Legacy of the Sith expansion completely reworked the game's UI and switched to a «combat styles» system so that players could essentially switch to any class that shares their weapon type, be they Republic or Sith. The game has seen countless other changes such as multiple iterations of its talent trees, reworks to Galactic Seasons, and plenty of balance changes, but the aging technology beneath it all has persistently held the game back.

Star Wars: The Old Republic Finally Transitioning to 64-bit Code

The game's new 7.2.1 update aims to change that by introducing the incredibly ambitious 64-bit client that has been on the game's Public Test Server for several months. This is a significant step forward, as the 64-bit client allows the game to access practically unlimited memory in comparison to a 32-bit client's limit of a measly 4GB of RAM. SWTOR has had to design its environments and encounters around this limitation, so the 64-bit upgrade enables the game's developers to create far more complex scenes using more detailed assets. The upgrade also opens the door for other technological possibilities, as The Elder Scrolls Online also uses SWTOR's HeroEngine and its 64-bit upgrade
