Earlier tonight, I managed to get my PlayStation 3 controller to work with my tablet PC as I played Assoluto Racing. All I needed to do was change up some of the controls for my game pad and play. I used an OTG cable to connect to my wired PS3 controller. I had to press the PS button once when I realized I wasn't moving on the track. Other than that, dare I say I have more accuracy when playing with a controller! I don't expect Gran Turismo ease of driving, but the game handled quite well with my wired experience. I didn't want to fiddle around with trying to get Bluetooth to work, so I kept with the wired PS3 with the OTG cable. I still had to use the tablet screen to navigate through menus. It otherwise played very well. I had better control using a controller than I have in having semi-awkward usage of tapping the screen controls to operate my vehicle.
This is just more credit in Assoluto Racing being a very solid mobile sim racer. If I had more space available on my tablet PC, I'd finally get an update complete for Assoluto Racing.
