This post might show up twice. I think Gitlab ate my first one, or I posted it elsewhere by accident. I don't know of any d3d9 games that depend on the flip swap effect. This was mostly a thing in the DirectDraw days. Prince of Persia 3D and Empire Earth 1 are two games that recycle the frontbuffer contents. Pop3d in the main menu and Empire Earth for the in-game HUD - but only with some graphics settings. But even for these two games I don't expect a visual difference between copy and flip. The DirectX 7 SDK has a ddraw sample that differentiates between "odd framebuffer" and "even framebuffer". Oh and I also believe I took care of swapchain texture shader resource views when I implemented swapchain rotation. But that was 10 years ago, so maybe my memory is wrong. Or we decided to ignore the issue until we spot a game that actually needs it.
