So I have been reading the post in this forum about firepro and I start to be fairly disappointed with the acquisition of our AMD W600.
AMD itself announced a LONG time ago support for edge blending and projector overlapping. See here for example. I keep reading everywhere: "yes the support for edge blending will be available later this year". Two years after the launch of the graphic card there is no official release of dopp, it is just unofficially supported and there is no documentation. I've been struggling to put the pieces together and make it work.
I don't want to blame the developers. I don't know how is the situation in AMD but if you don't have the resources to develop a feature then DO NOT advertise it and mislead the customers.
We bought the W600 only to create a projection wall and now I'm not completely sure if it is going to work. I started wondering if there is a fundamental bug in the hardware that does't let AMD finish the implementation of DOPP.
However, thank you for posting the code. Without it I would have to trow my W600 in the trash bin.
