I played for quite a long time last night, intermittently fiddling with the settings. At one point I had everything almost maxed out and it worked fine until I docked and pulled up any menus, then it was stutter hell. So, I went back to my "low" settings and it was fine. Overall? I didn't see much of a difference regardless of the settings I set. However, I did not test in all situations, all settings, all environments. Also, even at my "low" settings still got some stutter, in particular around planets and hyperspace.
TL;DR: same as 1.2.
