Yes I installed a Samsung 970 M2 500GB SSD before installing MSFS which is fast at over 3GB per second. I can see every update making the program bigger and bigger and will not be installing the Japan and America scenery updates and being very selective on Addons.

Thanks , yes I guessed that was the case just to tick what you wanted to load. How are your start up times ?

I have to have my PC on Universal Time. If I have it on Local Time I get a message on starting MSFS 2020 saying " Please Insert Disc". As unlikely as it seems this was a solution given to me on the Forum and it worked.

I have noticed that each update seens to be increasing the start up time. I have been recording the time on a fairly good gaming PC from the point of clicking to start to the menu selecting the flight then from there to the button to Fly. It used to be a couple of minutes total but now after the latest Nov 24 update it is over 4 minutes. Addons of UK Scenery of 8 GB into the Community Folder have made it 8 minutes. I tried the utility that creates links in the Community Folder rather than having files there thinking it might reduce the time but it is the same as I expected. So it is a case if clicking and then going away to make a cup of tea so no big problem. It is clear that the more Addons that I load will increase it so I am reducing them. It would be better if it only loaded the scenery for the immediate area you have selected to start the flight. I still think it is a very good Flight Sim.
