How about you answer the question and stop deflecting....
The physics are decoupled from the renderer. They use interpolation in order to allow the renderer to draw a higher frame rate than 60. The advantage to running an unlocked framerate above 60 FPS on a 60Hz monitor is that when it draws out to its screen it will use the last frame generated by the game. The image presented on screen will therefore be more accurate, in terms of yours and other cars position on the track, than if you were v-synced at 60 FPS. Of course some people can't abide screen tearing or prefer the smoothness of a locked 60 FPS so run with v-sync.I'm just stating facts. It may well draw more frames, but the calculations between them haven't changed. Go argue with David Tucker on the forum if you know the software he develops better than him!
If you're set on triples then I'd definitely make sure you stick to 144Hz. Going back to my 60Hz triple 27" 1080p screens from the 90Hz of the Rift is.....yuck. Can't imagine how much worse it would be from 144hz, assuming you are hitting that at the moment.60hz ok for racing? I'm so used to 1440p 144hz freesync now? I was thinking of buying 3 brand new 24" 1080p 144hz Freesync screens as I'm worried buying 2 different 1440p screens to match the one I have will look odd as this monitor was £600 alone. Plus, I'll then have the mismatch in colours also. Plus triple 1080p way easier to run than triple 1440p lol. Thats like 11 million pixels where as 4k is only 8 million.
I'll be playing Project Cars 2 and Raceroom as well as iRacing, but we know iRacing is nowhere near as demanding as the more modern racing titles.

Incidentally note that some of the physics subsystems, such as dampers, run at way above 60hz.
My GTX 980Ti has basically died, intermittent loss of monitor signal, took me a week of messing around to get to the bottom of things.
Overclockers have said out if warranty and try the manufacturer.
