GT DD Pro causing very choppy performance
We all know that you must use compatibility mode with iRacing however even compatibility mode can cause extremely choppy (absolutely unplayable) gameplay at times. Seems the rev stripe works randomly and when it does the choppiness begins. The only way I have found to clear this is to cycle through the modes all the way around back to PC compatibility mode (while in game) and it seems to clear up. If you switch sessions or even pit this symptom can reappear. I love the performance of the wheel and base when it is behaving properly hopefully there will be a fix coming soon.
