After owning a console for some time, I just upgraded to a personal computer. Accordingly, I initially attempted to connect a PlayStation 4 gamepad using Bluetooth 2.0 so that after the image was displayed on the TV, I could play like I used to in the traditional manner while sitting on the couch but with a higher resolution)). Connection achieved through the use of programs, characterized by constant dumps, high signal latency, and dancing with a tambourine. I was under the impression that it was a matter of dual shock when I made the decision to purchase a controller from Series X. Sadly, the previous adapter was not compatible with the new gamepad at all. I came to the conclusion that I needed a Bluetooth 4.0 adaptor. Everything performed as it should have, but when playing together, the gamepads from Sony and Microsoft seemed to interfere with one another, which resulted in interference on both of the devices. After that, a decision was made to utilize this adaptor, and WOW! Everything worked, there were no delays or dumps, and the connection was made in a single second just as with a console. In general, the purchase of this item is required if you do not want to be able to dance while playing a tambourine and if you want to do so comfortably.
