Hi Forest; We have same problem and I find that threading isn't actual problem. real one is rendering on specified HWND. And frame rate always gets down while enlarging the HWND size contrary if you collapse the HWND size you can see easily that frame rate gets upper degree than wide one. I suspect that low frame rate is caused by rendering on specified HWND. If you really need to render on MFC control(i.e PictureBox) you should narrow you HWND control size to get high frame rate.
