As was mentioned already in the last few blog posts, a lot of the work that we have been putting into the upcoming Manstein build of Heroes & Generals is aimed at improving performance. One of these improvements is asset streaming.
Lock & Load
In all the previous builds, the game would load all of its assets (geometry, textures, sounds, etc), every single time you launched a FPS match, using up a large amount of memory, preventing some of the lower-end graphics processors from running the game at all. Starting with the Manstein build, textures will be loaded on the fly (i.e. streamed), as they become needed.
