Hey;
I could use some help, I'm trying to do the RESZ-resolve of a depth-buffer (AutoDepthStencil D24S8), but I can do the resolve exactly one time, then the surface remains static:
The context is:
The code to resolve (ResolveDepthBuffer) is:
I've thrown a lot of stupid stuff into the code to see if it changes anything, the Begin/End are not necessary, I don't even think the GetDepthStencilSurface is necessary, the SetRenderTarget may not be necessary. Despite being an official feature there is nothing to be found in the net (no code, no explanation, nada). I can provide links to the entire code-base if necessary.
Please, help ...
It's the remaining piece to enable MSAA in Oblivion, while having the depthbuffer for effects.
