If you have the issue with broken graphics when driving at high speeds, try setting the ini parameter CameraZoomFactor = auto to a hardcoded value. It's currently calculated this way: ((AspectRatio) / (4.0 / 3.0)) * 2.5. Find out what that value is for your resolution using this link (e.g. for 2560x1080, CameraZoomFactor = 4.44) and set CameraZoomFactor to anything less than that (e.g. for 2560x1080, CameraZoomFactor = 3.8).
