The A variant of the F1 was not unique to the SAAF as it was also exported to Libya. Between 1978 & 79 a total of 16 were delivered to Libya as the F1AD model.
Same for me, with civilian traffic on any setting other than off, N2 is a stutter fest even in unpopulated areas. When I set it to off, I get a steady 60fps with vsync on over London & Paris.
I noted some time back that the air speed gauge on the Mig-29 has been changed. There is a white square on the "0". I searched photos of real Mig-29 cockpits and I could not find a similar case in the real world. Does anyone know why ED made this change to the gauge?
