You might be asking yourself, can you play Microsoft Flight Simulator on the Steam Deck?  The Answer is Yes you can and here’s how you would do it.

Before Installing Microsoft Flight Simulator 2020

Before we even begin installing the game onto the Steam Deck, we shall have to do some things to better make it more likely to run. You’ll probably need at least a minimum of 256 gb of space on the NVME.  I have tried to use the SD card that is was was fast read but slow in writing and that caused problems with the game.  You’ll need to have something that can do fast writes and that would require a NVME or some way to use an external hard drive that you can plug in while you play the game on the Steam Deck.   However if you don’t have the room due to it having a small amount of storage to begin with then I have some good news.   Amazon has started selling NVME that are 1gb of space for around 60$ to 70$.  The Minium hard drive you should use is a 512gb then you should be able to install the game.  The Game requires a massive amount of space that including the world updates that come along over the years which are free. So you want to upgrade your SSD on the Steam Deck, huh? I created a good blog post on how to do it even more but this is about the game and you should at least get the biggest Hard drive you can and that would be a 2 terabytes NVME which does cost a lot but would allow you to have the game and other games installed.

How I did it

Now we get to how I did it because this worked with me, I got a copy of the Steam deck OS image and re-imaged my Steam Deck.  You’ll want to use Rufus or some other imaging software to create a boatable USB drive and boot into that the Steam Deck.  This is the best approach to make sure you have enough space for a the game if you only have a 512gb installed and it is also good just wipe the hard drive because you never know what files are left after you installed a game or not.

If you are doing the install my way, you should update the OS once you boot into the Steam Deck. Log into your account as if this was your first time using the Steam Deck and check for OS updates in the settings.  Don’t install any games yet because you should also be using a Dongle of some kind or dock to speed this process up a bit.   You can use wireless but it will more than likely take twice as long and that can be time consuming to say the least.

It’ll take while to install the game

It’s like a 130gb or a bit more to install the game once you have installed the initial game from Steam which is like 3gb or so.   Make sure to install it on the main hard drive and don’t select the SD card because it will not work more than likely.   It took me about 3 or 4 hours of just keeping the system active while it was download the packages from Microsoft which uses AWS(Amazon Web Services), so the speed isn’t going to be fast.   I would say if you are on dock plug in a mouse or something and occasionally move the mouse while it downloads from Microsoft.   Again this can’t be helped no matter how fast your speed is on your network.   However before you click on the game the first to actually download the files you are needing to install from Microsoft, you should go into the properties and select the Experimental.  This is under the compatibility menu in the game.   You’ll need to make sure that is selected and experimental proton was downloaded from Steam before you can run the game.  Also you’ll need to add the -FastLaunch in the launch options settings.

Community Files on the Steam Deck

Does the steam deck have a community folder for Microsoft Flight Simulator?  Yes it does.  So you want to add your community files you have on your Windows Systems to the Steam Deck, the good news that can now be done on the Steam Deck.   You’ll have to go into Steam Desktop and navigate to the right folder.  Once you do that grab a USB that has the files on them and put the USB into an empty USB slot.  Once done, open up the drive and folder where you put the community folder in and copy all the contents not the folder into:

Where’s the community files located on the Steam Deck?

Go to your steam deck desktop find the home folder.

Before you can find this folder, you’ll need to hit Control + H to show hidden folders and files.

/home/deck/.local/share/Steam/steamapps/compatdata/1250410/pfx/drive_c/users/steamuser/AppData/Roaming/Microsoft Flight Simulator/Packages/Community

You’ll want to have a fast USB drive to do this because I am sure the community files will be more than 10 gigs of space at least that is how much mine was, so using a USB 3.0 device is something that helps you move the files over quicker.   However that just depends on how much you have to copy over.   Once that is done you can boot back into Steam environment or just reboot the system to get to the steam menu like before if you aren’t that knowledgeable about this that is one way to do it.

Finally I suggest you just start installing all the world updates you want it just depends on how much space you have on the NVME.   If you have a 2gb then you can possibly install all the worlds and that would be around 300gb of space or something like that.   So you just have to be mindful of that and also which community files you want to install on the Steam Deck. Once you have did all this you can begin to play around and setting it up the way you like to play the game.  On Battery power I would assume it will last around an hour and half on the LED Steam Deck and the OLED probably a bit more since they have a bigger battery.  I haven’t had a chance to see how long it will last on the Steam Deck on battery but I would just be mindful of that and have the overlays showing you how much battery power you have left.

P.s. on a side note someone was asking if Microsoft really did use AWS.  I did do a check on this on my desktop and they are going to the AWS servers:
