    DX11 frame rate drop at around 1.5 seconds

    Has anyone experienced an issue with DX11 where at about 1.5 seconds into the frame it drops the FPS from 60 to 55 for a split second? I create a blank application with no objects or events, only changed the display mode to DX11 and it happens every time.

    Yes - I loaded a game and on my logo screen - after the initial drop when it's reading from an ini file - on DX9 it will stay stable on 60/61 fps. On DX11 it will drop to 55 quite a few times - I was doing nothing - just watching it. Some times it will drop to 55 quite often, other times just once in a minute but I couldn't work out an exact fixed pattern.

    But currently the debugger is very sensitive to what's happening in Windows - you can watch it drop like crazy if you interact with something in Windows or if Windows changes something - like your desktop display.
