Does MSFS 2020 fully work in my Boeing 737 Sim?

Since releasing the video of us flying the sim with MSFS2020, I get lots of questions about it. Instead of answering the same question over and over to different people, I will write it here for everyone to read if you are interested.

I can say after two full days of pretty much non stop flying, Prosim 737 is in another class of its own, its quite literally awesome in every aspect! (It's also very very expensive). Prosim allows the cockpit builder to achieve there desired build in so many different ways. It also allows you to interface many types of hardware. It's this uniqueness that has allowed Prosim to get the 737 into MSFS2020. If you want a display screen on another computer or monitor, it just works with a few clicks of a button.

Im guessing Prosim runs all the logic for the aircraft and they supply the flight model, MSFS is just used to display the graphics and flight characteristics and Prosim is doing the rest. Every system appears to be working, every switch operational (that we have tested). This is where we are actually very luckily in that all our interfacing is done with Mobiflight and FSUIPC offsets. So we are not necessarily using the offsets to read from the sim, but to use the offset data to communicate between the hardware and Prosim server.

To get going, the first thing you need is MSFS2020 along with Prosim 737 Trial or the full version (V3 beta!). If you want to trial the software and see the awesomeness, get it here:

This is perfect as you get full operability of the programme but it must be reset every 30 minutes. You can of course save all your data and programming.

Then FSUIPC 7 needs to be purchased. Prosim 737 Beta includes the MSFS flight model. I have found that having no cockpit view on the main screens really allows you to gain extra FPS.

With all the software above installed, we had to make a few changes to Prosim 737 config.

The first is changing from FSUIPC to Simconnect (even though our whole sim runs on FSUIPC) under the simulator tab.

Then it's over to MSFS. In the general options under flight model, select LEGACY.

Select the Prosim 737 aeroplane and you are set! It was that simple for us in the end. That got us in the air. We had an issue with the autopilot being way too sensitive, but we think the legacy flight model fixed this on the next flight. We still have over-sensitive rudder pedals.

The downside many people have commented is that you must use Nvidia surround to display the outside image. On a 180 degree screen, this looks a little odd at the outer edges. For us, it more than workable for the graphics quality.

Our setup is qty 3, 65" 4K TVs are used to display the main flight sim image. We can get 4k resolution on one tv, or 2k over two tv's, with the settings on ultra. (FPS at 46) I now have to sacrifice quality and resolution to try and get the image to fill or 3 tv's without it looking like a 1980's Dire straights MTV music video.

We have also discovered a little cheat that helps out greatly. Using windowed mode, we can shrink the window size from the full height of the Tv to only the visible area. This allows us to extend the horizontal viewing area with sacrificing FPS. Then we keep extending the horizontal size until the sim starts to judder than back it off a little. We also realised that when you change the size of the window, it takes around 10 seconds for the programme to stop juddering and resume normal running and for the FPS to stabilise. So there were points we thought we had gone too far, but after 10 seconds the FPS restored itself and remained above 30 FPS.

If I could get hold of another graphics card, I'm not sure if this would help or not. Certainly would love to try a 3090 out! But I would settle for another 2080. So whats our setup:

The sim display computer is an I7, 16Gb ram and an RTX2080TI card. This solely runs Prosim server and MSFS.

We have another old I5 computer, that runs Mobiflight, Prosim audio, Prosim Displays. This has two cards to cover 8 monitors. They are a GTX960 & GTX 1060.

One final note, I have read lots that people are using Fly Elise to correct the image, I do not own this software so unable to confirm.

Any questions or thoughts, drop a mention in the comments. This seems to be a very controversial subject right now, but for us, we are smitten by the eye candy! Compared to P3D, reloading a flight is instantaneous in MSFS, for those times things don't go quite to plan or you want to practise that approach again.

Happy Flying!
