--- Comment #5 from Kimmo Myllyvirta kimmo.myllyvirta@gmail.com --- The demo is not available from Steam anymore, and the full game is to be released soonish; http://www.pcgamer.com/outlast-2-demo/ "The demo is free, naturally, but it's only available until November 1—through Halloween, in other words."
I still got the demo installed. It doesn't show up in the Steam library, but it still exists under my steamapps folder, and starts with "wine OL2Demo.exe".
R32G32_UINT and R32_UINT were already added, and WINED3D_RTYPE_TEXTURE_3D crash (bug #40925) is also fixed. D32_FLOAT_S8X24_UINT is still missing. See also bug #41696, which is the same issue.
