My PC recognizes every button on the DS4, including both triggers, share, options, and the clickable touchpad. The triggers are recognized as digital rather than analog, at least by the program I'm using (Xpadder). Haven't tried it on any games where analog triggers make a difference yet. I'll have a proper review up in the ps4 thread. To answer your question, Ethan, some ps4 accessories can already be found in some stores, although they're apparently in high demand and are sold out in a lot of places. I got one of the two gamestop had.
Also, FDS, I'm not familiar with that program. What do I do with it exactly? What's it for?
Edit: Forgot to mention it also recognizes the PS button and the clickable sticks.
