Right so - just did a bit of a test on XSX, albeit without a big flight plan loaded, just did a circuit at LFML and put the copilot’s EFIS off and the EFB off after using it for all the necessary pre-flight stuff and things seemed better! still a bit slow but I’d say the sim lost a few seconds at takeoff and a few just before landing. Was a big improvement on before in comparison but still not exactly where I’d want it.
At least it makes me feel like I want to use the plane instead of wait for an update so that’s a win!
