In windowed it works fine for 2 minutes, then it all stops, move cursor over button, clicking it, all has about a 3 second delay. In full-screen FPS is 0, in other words the screen won’t update, I press something but nothing happens (yet it does, it just won’t show it.) If I alt-tab out and then back in I can see that whatever I pressed has worked, but it’s frozen and whatever the next bit is, press another button, alt-tab out and in to see what’s changed.
It’s completely unusable, the menu’s just DON’T work, I can barely navigate the options, been this way since release. Surprised they haven’t fixed it yet.
