Latest build is v52. Use SuiKaze Raider's TRAOD Updater to obtain newest version. It also includes a reworked launcher and graphical enhancements (ENB series).
In the game's settings dialog, navigate to the tab corresponding to your graphics card, then go down in the "Cubemaps Reflections" box and set Camera and Character update to Occasional
(If there's more than one tab corresponding to your graphics card, i.e. if you have a multi-monitor setup, do this for each tab that is "Enabled".)
