humm...strange, did it just happen the once or everytime? what other programs were open? Any Dx ones especailly?
I'll try to reproduce this some how though...what is your PCs spec? are you using nVidia or ATi? (Mind we have tested on both). Seems strange that it would display for a couple of seconds then stop .

When I compile in the IDE I normally use the Debug > Direct3D > Start with Direct3D Debugging (Ctrl + Alt + F5)
However I have used just Ctrl + F5 aswell.


As for the frame rate that is expected....it flips the surface as fast as it can without any frame limiting stuff. So on my PC I get approx 6000 fps and ~6300 when in release mode. NoteMe gets betwen 2000 to 3000. .
