Never seen it so far. What does it look like? How to see it? I have the RC and under Graphics I activated motion blur (set to "on") and also made sure SSR was set to medium or higher (as the RC-update suggested). Normally play in VR but also in monitor view I see no difference from the old versions. Am I missing something?
Use "Page Down" to switch to trackside cameras. When the cam is panning cars on track, the background will get blurred.
