After the latest update, my controller never worked the same as it did before this…very sad actually cause I can never be able to enjoy this game again. Tried contacting support and they basically answered me once then ignore me 
And no, I know my controller works fine because in every other single games out there, I use this very same controller and it works like charm. In Forza menu or overlays, controllers response fine. But when it comes to me driving the car, then input lag happens. I have no idea about how to fix this anymore. Already did RESET on the game, still same issue. I guess this is a goodbye to Forza, I suppose. Because I believe even with this post, the people here will just ignore my issue since they probably think I’m 1 of the minority having this issue and it’s no harm in making me suffer and choose to quit the game forcefully. By the way, my keyboard works fine while playing the game. And again, without controller, I can’t enjoy a racing game. So let’s see what Forza has to say about this. Will they choose to fix this issue or will they ignore? We’ll see. Oh, and send my regards to Ju1ce_Cannon for ignoring me for days now LOL
