O.k. missed that bit in the release notes and since the Mirari is the only working PCIe system I have at the moment I can't really test. For me it sounds like it will now tell you that it can't do 3D *shrug*

I might test later on how far I could push the x1950 on the 3440x1440 screen if that is of any interest, but 60Hz it won't be (maybe with an actual DualLink->HDMI converter).
