According to the forum topic GE极致优化篇===多快好省的挂机 (um, the title means something like GE Ultimate Improved Version: Fast, Resource-Saving AFK), you can modify the client to avoid loading certain game aspects. This is to help players who don't mind ugliness to AFK and multi-task (e.g. watch movies/anime, work with PowerPoint/PhotoShop, etc.) on a less-than-optimal computer.
Simply rename any or all of the following files in Granado Espada\ge folder to a different file name (e.g. rename bgm.ipf to bgm_backup.ipf).
- animation.ipf ~ animation
- bgm.ipf ~ background music
- bg_texture.ipf ~ background texture
- char_texture.ipf ~ character texture
- item_texture.ipf ~ item texture
- se.ipf ~ sound effects
To restore its default state, simply rename the files back to the original names. Note that you should always restore to default state before patching the game.
