Couldn't wait anymore, picked up the Ultimate few days ago.
First let's talk performance, I have a i5-6500 with a 970 and the situation is pretty much exactly what Digital Foundry reported. I can cap it at 30FPS and max out every setting or I can cap it at 60 and have to turn a couple of settings down. Although even after turning it down, I get a bit of stuttering at Surfers Paradise (The city area). But thankfully every other place it sticks to 50 - 60 fps. More than playable.
Car customisation menu lags pretty bad. Especially the Rim Style menu. You need a lot of patience to go through that.
Surely someone noticed that while doing QA?

BUT, despite all of that. This game is so much fun!

Probably the most fun I had playing a racing game in quite some time. This is pretty much all I wanted in a PC racing game. An extensive car list with awesome customizability and you can drive to heart's content. So far I have not exhausted events either. They keep popping up much faster than I can complete them. The cars feel great as well. They all have their own characteristics, but isn't difficult to drive (I have the steering set to Normal). Didn't get the wheel out still.
Because of this I looking over the performance issues, money sucking DLCs, awful photomode.
Btw is there a FG Club?
