Just got the PMDG 737NGXU for P3d v4.5.  So far I REALLY love it. I've just done some quick circuits around my local AP, and it seems silky smooth.

I'm using an i7 8700 3.2Gb, RTX2060 KO Ultra Gaming vcard & 32Gb Corsair "Vengeance LPX" 2666 RAM.  My frame-rates (so far) seem to be averaging in the mid 50's.

Have 3 unrelated questions tho:

1. I can't seem to figure out how and where to save multiple set-ups to try different settings.

2. Is there a way to make the cockpit view just a little wider?

        I'm zoomed out to .30 (which is as wide as it defaults to), and I just need to go a few degrees wider so I can see the autopilot switch without having to move the view.

3. Where do I go to find the PMDG Ops Center?  I can't find a folder or file that mentions it.  I want to find some more liveries.

Any advice is appreciated.

Question #3:  Do a search of all your drives - like "PMDG operations".  In Win 10, it may be in the Program  Files (x86)

Did a search for the Ops Center and this came up:

PMDG Operations Center.exe - System Error  "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling                                                                             the program may fix this problem."

Re 2, zoom 0.3 seems excessively wide. Make sure you have wide aspect view selected in P3D options. This defaults to off in P3D but is a big improvement for widescreen monitors.

Also you only need to use the AP switch once each flight, twice for an autoland. Why compromise your view just so you don't have to turn to see it?

My ops center is located at: C:\Users\<username>\AppData\Roaming\PMDG\PMDG Operations Center\PMDG Operations Center.exe

I have no idea why it installed there so it must be the default location. I install everything FS related on my E: drive.

That is where it is supposed to be installed. Also if you hit the windows key and scroll down to the "P" section you should find a shortcut there.
