I couldn't make the necessary jumping through hoops to get my Logitech GT to work with PS4 so there you have it, I bought 0 racers this generation. If I ever get to it, I'll consider. I'll check out the demo because it's free.
Note: This is a message to Sony. I am willing to pay 30-40usd just for a driver if this is a licensing issue due to MONEYS.
I'm sure people would be outraged to have to pay to get their wheels to work though, if this was an option at all, rather than thanking for the fix, even though they'd be saving 200 dollars because why not.
And this is a message to Logitech: I'm not buying a PS4 compatible wheel thanks.
