I replayed like half of Portal 2 campaign with the controller.
It may get some time to get used to it. For the most precise clicks like a small target far away, even using the zoom and the gyro I was getting anxious trying to do that click taking me 2-4 seconds for something that would take me 0,5-1 seconds with a mouse. May sound stupid but when this happens often and continuously it can give you that anxious feeling.
Apart from that, I can also see how the precision will most likely never reach the one from a mouse, as often when you do the click with triggers or some other movement, you tend to move a little bit the finger that is on the track. Also taking your finger on and off the track will cause this small shake in your pointer as the surface of your finger is not a single junction point with the track, but more like a circle that gets bigger or smaller while the track tries to figure out which point will follow, causing this small shake (even when using just the tip of the finger).
Precision aside I found a couple of issues with the controller.
1- I had to disconnect my HOTAS and any other gaming related input device, otherwise it would cause problems with the usage of the axis. But I think the culprit of this is Windows and its terrible input devices management, I am used to have this problem if I have multiple devices connected at the same time.
2- I found a weird (and quite worrying) bug or hardware defect. I played most of the time fine but at some point I notice that by leaving my finger on the right track and not moving it (neither the gyro), my view was moving slowly to one side. I made sure that it was not caused by the gyro. Changed to the standard controller profile without the gyro and yup, holding my finger on the track without moving it made the view go bananas just to one side. Tried to turn off and on the controller, nope, still there. Opened the browser of BPM and I couldn't even move the pointer. Close the game, start it again, first check the browser, still not moving at all (just the pointer, the scrolling is fine), and then I check in the game, it is solved, but as soon as I switch the profile again to the one with gyro I can notice it again, and I can reproduce the issue. Looks like is caused by switching profiles or by using the gyro. And the browser looks like never works while in game...
3- How the hell do you turn off your controller after closing the BPM? If you hold your Steam button you go to BPM. If you turn off the controller in the BPM, then you cannot leave as the controller is not working. Of course you can close it with the mouse, but that shouldn't be necessary
I hope the second point be a software issue that they can patch with a firmware update. Locked axis by software/hardware failure is the last thing you want in an input device
Did someone experienced some similar issue?
