I thought it would be something catchy and you would quickly get better, but no, at least not me and two mates have with tested (at least for a weekend every now and then gambled). So it's likely that it needs quite a bit to settle on time, probably you should intensively deal ever for a week with it and go again and again to be really better than is possible with the controller.
I tested the T300RS only with Drive Club, is yes, at least for the PS4 no wide selection of racing games. I think Project Cars would have been better off if it comes then, or a GT on the PS3. I'm a bit disappointed would deduct for my false expectations but no star! The build quality is great, the Force Feedback very powerful and also the pedals have contrary to some reviews made a very valent impression on me, both externally with regard to the functionality / usability. And most important, the feeling is great!
The withdrawn star is because my copy probably a defective power supply has (which is installed and not replaceable). Every now and then when I wanted to connect it to the power, it did not work, the steering wheel was no electricity and the engine was not running on. Plug few times out and in it went. Have tried it at various outlets in the room, but the error was repeated as well. As I followed the included short Instalationsanleitung exactly, I can exclude that I have done something wrong. Alone so of course I send it back.
