I noticed really low fps compared to previous experimental builds. After quitting the game, the values for render width and height are set higher than normal leading to performance issues due to 1.33x supersampling forced by the game.
These are the values written into dayz.cfg after exiting the game:
Render_W=2553;
Render_H=1436;
Resolution_W=1920;
Resolution_H=1080;
