I have tried to configure my game to use the ps4 controller but it just doesn’t accept any input of the controller
Doesn’t a PS4-controller disturb the sales of official Microsoft peripherals?
Please be aware that DX12 and Windows 10 (which includes the Xbox One) has got a different code to interpret peripherals; this is one of the reason why older steering-wheels and such do not work anymore. I can very much imagine no support is in place for a PS4-controller.
Thank you for posting your feedback and request.
