Started TSW3 this morning and despite DTG saying it would be there there is NO option in my settings for turning motion blur off!
If someone has a huge aversion to motion blur in TSW (like me), they can turn it off (if realy realy necessary) with CTRL + F2. This is also possible on the XBox console, as long as you have a USB keyboard. You can plug it in and it should work in the XBox-menu and TSW. I'm not sure about Sony. But: Keep in mind, it is just workaround. You have to do it each time you start the game. An option is realy needed. I love to zoom in to the wheels; me and a lot of other people. :/ They can't ignore all wheel-zoomers.
I have the ability to turn it off now on Series S, however when I do, I get flickering pixels on the right side and bottom of the screen. This only happens in HD mode (which is what I prefer to play in as I play in 1080p due to the TV i play on not being 4k). Another note, these pixels are only present when playing the game, they vanish when I bring up the route map.
