Hello guys ,
Flight Simulator Blog ( Performance Boost Tricks ) , suggests to delete 60gb of hard disk space by removing the offline mesh files of the whole world !
If i do this , am i going to lose anything , or am i going to have any issues running my sim ?

I’m also interessted in this. I just wonder what will happen, when you fly offline e.g. forced by a random disconnect or when the MS servers are unavailable. Will we just see a black world?
Or at least maybe we can delete these files based on contries or continents, so that we could remove areas we never fly around.

the even better tip right below the tip of removing the 3D mesh for the terrain and removing all textures for the airplanes is dumping buckets of destilled water over the PC because watercooling is better, and uninstalling the sim and looking at cockpit photos until the GeForce 10090 GT Ultra series is available because the desktop runs with fluent 99999999999999999999 FPS while the sim is stuttering with unFLYable 30-50 FPS… (unFLYable because the common housefly sees this like slow motion slide projections while for every human eye everything with about ~35FPS looks and feels absolute fluent).
Don´t take every tip on the internet too serious

I deleted these mesh files on both my PC and my sons PC over a month ago. Everything is working just like before. We have seen no changes what so ever.
We did it to save disk space…

yes you can delete all those files , they are only needed for offline flying or no internet connection available
I deleted all of them and everything is OK
in case you are afraid, just move those files to another folder and give it a try, if you find anything wrong with your sim just put them back
best regards

It probably works fine until you get that “There’s a problem with your internet connection and you’re being switched to offline mode” pop up that prompty crashes your sim.

I would like to understand why they are downloaded but not used. Why should we stream the same data that is already on our hard drive? Would it not make more sense to reduce the data transfer, then use the available throughput for the things that have to be streamed like, weather, AI, scenery, etc…

Well with around 60 GB of hard disk storage you can not have high quality textures for the whole planet. Once you have flown the first time in offline mode, you will know what flight simulation looked like a few years ago… MSFS can become ugly like FSX without any addons.

Actually no. I tried it out. Once the sim switches to offline mode because of any connection issues, you will still have some really basic world. I took a screenshot with the payware EDDK airport for comparison:
I think I will make a copy of these files and move them to an external drive, just in case I should ever need them again. Maybe when MS stops the development in some years.

Could someone please post where these files are? I could sure use the space on my drive. Thank you.

Thanks guys for the feedback !
I have cut and past the files in another ssd disk in my Pc ( Just In case ) !
Everything is working fine at the moment 
Go to :
Windows ( Drive Msfs2020 Is Installed ) > MSFS > Official > One Store > Fs-base-cgl > CGL
Remove all the Numeric folders total of 60gb , from CGL and leave DB_Notices.txt untouched !

You could try making a symbolic link to the place you moved them so MSFS can still find the folders if it needs them. Think I’ll do this as I’m running low on space on my installation partition!

Great
I have no idea how to do this !!
There is a guide here: I'm eventually going to run out of space. Split installs? - #5 by SvenZ
But I ended up using this app as I found it most understandable: GitHub - amd989/Symlinker: Symbolic Link Creator. GUI for mklink, Microsoft Windows symlink utility

Hello. I followed all the advice on the blog. On the other hand, a manipulation that I do not understand… Put a value of 30IPS in the Nvidia panel. If I do that, my Sim gets stuck at 30ips instead of 60 normally and my MainThread goes from 14ms to 40ms… What is the purpose of this manipulation? I often see videos where the creator reports having blocked his FPS at 30 in the Nvidia panel but with him everything is smooth… Something I didn’t understand?
The guide is based on a RTX2060 and i9 9750 if I’m right. The idea is that it feels more fluent to have 30fps all the time than a fps that goes up, drops again etc. I’ve it a bit higher but it depends on your system. Not sure about the current energy prices where you live… but if you lock it at 30fps you do save a lot on the energy costs as well.
