Hi,
I'm trying to make a screenshot with a timestamp but for some users they sometimes don't get the timestamp on the image :S
From the WndProc I call the CreateScreenshot function which looks as following:
lpD3DDevice->BeginScene();
lpD3DDevice->Clear(ZBUFFER | STENCIL);
draw timestamp as text...
lpD3DDevice->EndScene();
lpD3DDevice->Present(...);
LPDIRECT3DSURFACE9 lpSurface;
lpD3DDevice->GetRenderTarget( 0, &lpSurface );
D3DXSaveSurfaceToFile( fileName, D3DXIFF_PNG, lpSurface, 0, 0 );
lpSurface->Release();
I'm not sure why sometimes this doesn't work. Can it be possible it has to do with the monitor vsync? Like it ignores the new rendered frame..
Thanks for reading ;)
