The right 2D HSI  freezes for me, however, I just increased the refresh rate of the right HSI to MAX, but I don't think I will see the results until I finish the current flight. I'll let you know if it stops freezing for the next flight.

Edit: I used ACE to increase all the Definitions to HIGH, and all the Refresh rates to MAX, and I'm seing the expanded 2D displays matching the 3D displays.

One thing I have noticed on the last two flights, is that the EGT of the left engine is constantly ~11^o hotter than the right engine, the oil pressure of the left engine is 1 (psi?) more than the right engine, and the left engine VIB is +0.1 more than the right engine VIB.


Note. I haven't tried it in P3Dv5 yet.
