MX Simulator

I'm having trouble with my controller. Input mapper is bugging and since then i can't use my brakes and gas together.
It would be nice that mxsim has a ingame controller support cause ive had 20+ times when input mapper or ds4windows shuts down randomly.
I think and hope that this could be possible in a few weeks cause currently i can't play mxsim

I have never been able to throttle when on the front break since I got this game. Would be nice for better support.
