    Quad Buffer in D3D9Ex vs PresentStats

    chura

      Hi,

       

      We have tried to implement steroscopic rendering in d3d9Ex, but seems it cannot work together with Ex's present stats:

      - QuadBuffer's PDF says d3dPresentParams.MultiSampleType must be 2 and more (otherwise driver/hardware hangs can occur)

      - d3dPresentParams.MultiSampleType works only with D3DSWAPEFFECT_DISCARD

      - D3DSWAPEFFECT_FLIPEX is required to be able to get PresentStats in windowed mode

      PresentStats are essential because of frame-accurate video rendering

       

      Also, it seems to be impossible to display stereoscopic content in window on AMD/ATI cards. I've been thinking that then maybe the stereo can be disabled when switching to windowed mode, but seems that even after multiple d3dDev->reset() the driver remembers the 'stereo enabled' flag, and there is no ATI_STEREO_DISABLESTEREO, is there?

       

      Can anybody suggest any workaround?
