A few issues I am having with the NGX. First let me say that I have followed the intro document and the only thing I am not following exactly is that I am using FSUIPC but with a profile. Also, I have done the tutorial and did not have any problems. 1) Sudden frame rate loss to 1FPS followed by crash of FSX. Sorry I cannot give more details but it was right after takeoff. 2) Using 2 screens the sound stops when you click on the second screen. I have my FMC 2D window on the second screen. Second screen is also using iGPU on my 2500K / Z68 board. This is not a problem with other addons. 3) VNAV will not engage. I forgot to engage on the ground but now flying in LVL CHG and no VNAV. LNAV is fine. Plane is trimmed, if I turn off the CMD it flies true. Mark W.

The VNAV thing must be user error because I just got it to work. I went into the CRZ page then LRC then back to ECON then hit EXEC and the CRZ ALT and TGT SPD turned magenta. I hit VNAV and it lit up. Guess I will have to do some reading on this. Mark.

The VNAV refusing to work is a bug, because you can get it to work by doing certain things such as reloading the saved panels. Henri
