DX 11 Tessellation Crossfire Problem that ATI won't talk about....Notd3d11 AppWindow ******I originally wrote this thread about another problem. Because I thought the MS DDI 10.1 bug was causing this problem. But..... I found out it wasn't the problem. So since then the thread has kind of gravitated to the real problem of ATI's Tessellation Crossfire problem. If you feel like chiming in here please feel free. I know there is another thread similar to this..... but it hasn't got allot of notice. So I am trying to find answers about this problem. The problem is described towards the end of the page. Sorry And thanks******* Hey guys I recently just bought a XFX 5850 to go with my Diamond 5870. I also got a new motherboard if this info helps for what I am going to tell you.....(Which is a MSI GD65 P55 Board) Anyway ..... I started installing some games tonight. I went to go test them out because this is my first..... Xfire setup. Well anyway any game so far running DX9 and in DX10 will work fine when in Xfire. But if I run a DX11 Game it won't run fine. What will happen is that it makes the game pause...... then it will make the Driver Crash and either makes it so I have to reboot ..... or it will give me this error below..... d3d11 AppWindow::do swap(): device removed I am completely lost..... I have no Idea what is going on here has anyone had this problem or know anything about it? If so please help...... Or if you have any suggestions on what to try please let me know..... My specs are as follows..... MSI GD65 P55 i5 750 XFX 5850 Diamond 5870 Corsair 850 HX Corsair H50 Corsair XMS3 RAM Western Digital Black Carvers Thanks...... I won't be around tonight to answer questions.... but if there are some suggestions for me to try..... I will gladly respond back tomorrow.
