Thank you very much, finally its smooth even at 60fps! :)
I can activate stereo 3D with exclusive mode. At medium graphics settings Desert level is stable 60fps, but the Forest is not. Even at lowest quality it cannot do 60fps. I have a 750Ti card, time to get a 1050Ti? :)
Another question: is it normal, that my controller has around half sec delay? When i play with the throttle for example, quickly go to max, i can hear the motor's sound only after 0.3-0.5 sec. I have a 24 in 1 usb stick with A8S PPM receiver and i6X radio. But i tried with my wired usb simulator radio too, with the same result. Maybe a settings in windwows game controller properties, or you have to change something in Unity?
