Ok, so I had the wheel for two days now. I'm using the the GTE rim for it, which feels nice. The wheel is good and if you don't have a wheel, it's a good one to get for sure. However, I was a bit underwhelmed by it at the same time.
I've had the DFGT before it and at least pCARS wise the upgrade is not massive. Yes, the FFB is stronger and can be made MUCH stronger, but the way I set it up now it's marginally better than my old wheel. It is better, for sure, but if you are tight on money I have to say that DFGT worked very well with pCARS. There is a bit more details coming in now with my new wheel and the wheel feel is more like the real wheel in a real car.
So if you don't have top of the line wheel, I think you will still be pretty happy with how the game feels.
