I have to say i'm disappointed with the final content of AC. To put it politely it's lacking...the whole build up to the announcement just made it more of a disappointment.
I have 30+ hours in AC now and it doesn't compare to pCars in most areas for me. It has better force feedback and more popular online servers, but these will be moot points once pCars is actually finished IMO.
I guess it's nice that I have both. They are easy to jump between and not feel out of touch with the physics. And the AC drifting and modding community is brilliant. But the stock game leaves a lot to be desired. Where as pCars has brilliant content already.
Shouldn't complain though, it's a great time to be involved in PC racing sims again.
- to the poster above, I am running it maxed out at 1080p and getting 40-50fps.
