I can see that you are trying to create a driving simulator using the Vehicle Dynamics Blockset and Unreal Engine.
As per the documentation of Vehicle Dynamics Blockset, if your system is satisfying the minimum required specifications, you can supposedly run the simulation at the required resolution. Also, Unreal engine can run at any resolution provided there is enough GPU compute available for rendering.
For more information on the system requirements, you can refer to the following MATLAB documentation: Unreal Engine Simulation Environment Requirements and Limitations.
