AHAHA, yo have many things to learn, the UE4 can do more and more than the rF2 engine, just you need to implement the good physics datas. All depend of what you do, it's maths and physics code, wrong code, wrong physics. I can assure than the UE4 can do more than the rF2. The UE4 like all the 3D engines execute the code, bad code, bad things. The problem is it's ISI who has implemented the physics code in the ISImotor game engine, maybe Kunos, s397 and Reiza are not as good to implement the physics data code . Maybe ask to ISI to code the physics in the UE4 , cause all the glory for the physics code in AMS or rF2 is going to Image Space Incorporated. And respect for Kunos they create themself the physics, they have not used the ISI physics. Maybe s397 and Reiza fear to create themself the physics, cause ISI will not be behind them . Triple screen support ? you have to code it. VR ? you have to code it. Do You want something ? You have to code it, the only limitiation is your imaginaton. Look at this: It's the perfect example, the physics depend of the code, and cleary , the code implemented by UE4ARch team is not as good as the ISI physics code (of course they are not Sim racing developpers). Bad code = bad physics, good code = good physics. Edit: the "disagree" fucntion is a code implemented, do you like it ?
