Performance Improvements in 2.3.3

When we launched Path of Exile 2.3.0 alongside the Prophecy Leagues, we added multithreading to the game client in the form of concurrent resource loading. Until now, though, we didn't have multithreading for regular gameplay. (Multithreading is where multiple CPU cores are used simultaneously to perform different tasks, improving the game's performance).

In 2.3.3 we will be adding a command-line option that will let you turn on frame multithreading. This feature allows the game to use more of your CPU cores for regular gameplay. We hope to have this feature enabled for all users in 2.4.0.

As shown in the video, in high action situations we have seen performance improvements of more than 2x the regular frame rate when bound by CPU performance.

This is the second round of our performance-focused improvements, but we are not done yet. We still have a port to D3D11 and much more planned for the future.
