I have a setup with six displays hooked to one PC via two GTX770s. I am happily able to use DX9 textures across all these displays using the usual multi-monitor viewport scheme, EXCEPT for the textures coming out of a FileStream/VideoTexture chain. Even HTMLTexture works across all monitors over both cards.
I get the correct part of video playing on one monitor, the others are dark. I can change which monitor gets the video by changing the VideoTexture Adapter input pin. I tried re-rendereing the texture via a Quad/Renderer/EX9Texture chain, same result. I need the /dx9 switch, so I cannot try a shared texture.
This is with 33.7 x86 on Win7. Any ideas? Thanks!
