I recently reinstalled a fresh copy of windows and Unreal 4.11 and 4.12
Everything runs great as long as it’s one window.
If I undock the contend browser, the performance halfs;
undock the details pane and open matinee it’s down to 3-4fps.
Also, when I click on a dropdown button, like the one for matinee, the dropdown animation seems slow and there’s a noticeable stretching in the text for a second before it’s displayed properly.
I’m attaching my dxdiag to this question in the hopes it helps.
Any help would be greatly appreciated.
