So I went into a Canadian EB games today, and as had been reported online, they were stocking Dualshock 4s. I picked one up and quickly brought it home for testing on the PC.
First off, the thing feels great! Sticks; triggers; handles - all top notch improvements over the Dualshock 3.
Now we come to the bummer part. While my Windows 8 PC does detect the DS4 as a gamepad when plugged in with a Micro USB cable, it does not work flawlessly out of the box. While all of the buttons register, one particular issue makes games unplayable: the X & Y rotation are mapped to the triggers instead of the right stick. This means that, as the triggers are depressed at their default position, those axes are at a value of 0 (instead of the desired 50, or center position). The end result: constantly spinning camera! I tested this on multiple Steam games and found the issue to be persistent. If the issue wasn't present, however, it was because the controller wasn't recognized at all (as was the case with Bastion).
Knowing full well that I would probably get nowhere, I contacted Sony support and asked a) if they had any documentation on the DS4 and b) if Sony was planning on putting out drivers for the DS4 when the PS4 launches. The answers were "no" and "we don't have an answer at this time", respectively.
Anybody out there with a DS4 that found a workaround to this?
p.s. before somebody says something along the lines of "well it's Windows 8, so I'm not surprised that it isn't working for you", please note that a score of unboxing videos on Youtube show this same problem on multiple Operating Systems.
