Sorry for my early hardware issues. My first couple bobbles were definitely not helped by the fact that I was so far "behind" reality in my headset. I was a good 3-4 frames behind what reality was, which makes controlling a car at Nurburgring...interesting.
I made some performance tweaks, but unfortunately it's really hard to test for that specific condition (e.g. Nurbugring with a full split of cars). Performance was always fine in practice, and remains fine...but I'm keeping my fingers crossed. I'll do some official races this week to see if my frame rate holds. I may have to go back to 90hz refresh for iRacing, because the cost of my frame rate bouncing up and down is really high. Makes driving very hard.
