As an update, I hopped on GT7 yesterday after not touching in Sunday, and so much just clicked for me. It's like my brain rewired itself after playing for a good amount on Saturday.
I'm nowhere near good, but I finally understand how to tell when the car is about to brake loose, how to run it into the corner at speed while braking properly, how to trail brake it in the corner (and feel it), etc. I found that I got in a zone on many races. Last night, I did the Porsche circuit where there's one guy in P1 that's pretty quick (for me at this point), and I was able to take gold overall on my 2nd attempt (bronze was the 1st attempt due to having the wrong tires on the first race w/ rain).
Now, I know that there's a TON I'm still not dialed in on - especially knowing where the limit is with each car / track, but that'll come with time.
I'm going to mount some transducers (I had lying around) to the rig tonight and hook up SRS.
This, to me, is a big step in the right direction as I'm starting to understand what to look for, and how to make decisions based on it.
Also, being that I'm new to all these cars, and all tracks (mostly), it's taking a bit to learn and really start to find my groove. It's not enough to know the track either, it's also how the game physics work with it and the car. Learning that Intermediate Race tires in the rain are about the exact same as Medium Sport tires on a dry track (which doesn't make sense, but it's how it worked last night) is a good example.
I still have plans to build out a PC sim rig, but man, I'm having so much fun w/ GT7, that it's hard to want to do as my current rig is small enough that I can roll it into my theater - which is really fun as I love to crank up music to the game.
