Now that I've had an opportunity to run the same setup, car, and track in 64 bit mode as opposed to the 32 bit mode I tested all day, I'm really amazed at how much better everything is! Unlike most other 64 bit applications where any difference is hardly noticeable, here the difference is fantastic! Not only are my frame rates higher and more consistent, but in general the graphics look 100% better! And everything ran faster and smoother! But what really surprised me, and for what I'm sure I'll be called crazy, I was able to get around the track using the same exact settings from earlier today at much faster times...and from, a cold start! Everything from sound effects to steering was just a little sharper and smoother. I felt like I was running a different Sim at first! Kudos to the devs for doing such a great job!
