Thanks. Sounds like they are going to offer the same functionality. That's the way AMD made it sound like it would work and that's good for us.The line mentioning Nvidia supporting ASYNC is fairly well translated by google translate. This would be my translation:
"While enthusiast are waiting to try AMDs freesync, Nvidia is planning on stealing the show, by doing the same* and implement support for Displayport Adaptive-Sync, despite the fact the technique is in practise competing with GSYNC"
*the swedish text says "doing the same", which is slightly confusing, since Nvidia is obviously not going to implement freesync, but I think they are referring to earlier in the text where they describe the functionality of freesync, and it is this functionality that Nvidia will "do the same".
