QuestionHow slow is GDI? Pin

Hi,
I have a simple program with a CFrameWnd. I override the OnPaint() function and draw some images. I preload a sequence of images using CxImage (separate objects for each one) and then I use CxImage::Draw() function to draw the particular image one at a time. The problem is that when I change the image being displayed (by changing some pointers to another image and just calling CxImage::Draw() on a different image in OnPaint()) there's a flicker as the images change. It's not that much and when the image is displayed it looks ok, but while the images change there's visible flicker. Is this due to how slow GDI is, or something I'm not doing correctly? The images are 640x480. How do windows that display movies work then (I'm not trying to display movies btw)?

By the way CxImage::Draw() after doing some weird things just calls SetDIBitsToDevice() Win32 function with the bits.

Thanks.
