I made two videos of using a stock PS4 controller from SONY and the Razer Raiju TE.
Game is Destiny 2 on PS4.
Both are wireless.
As you can compare the Raiju is almost about 2x faster. Which is bad.
I feel it should be the same as the stock Sony controller.
I feel the Raiju has great build quality. And it seems Razer is intent in getting this right.
I want to help. But...I only have so much money to spend on either the Raiju or buying the upcoming Astro C40.
I love the remapping of buttons in the app. It is a nice touch, but it always forgets and I have to resync it with my Iphone 8.
I have attached the version of the software as well to support.
I don't know if this helps, but my friend bought the same one and has the same problems.
Its really just the stick sensitivity that needs to be adjust to be the same as the SONY controller.
If you can fix that you have a great piece of hardware.
Also note, I don't post videos much so my editing isn't so great and I tried to reproduce this the best I can.
