I am keeping FSX for few more years until MS2020 is 100,000,000 percent ready
And FSX is not dead.
You'll be waiting a long time in that case as they are always updating and improving the new sim and thats the beauty of it - it just keeps getting better all the time!
Theres literally no reason not to go to either p3d or msfs2020 or XP11 if your on fsx, no one is creating addons for fsx anymore
Fsx is well and dead - its a 16 year old platform that is so outdated now
Its like using an old nokia brick phone compared to a new iphone ort samsung - sure the nokia will do its job but why persevere with such old technology when you can do so much more with an iphone or samsung...?
Since installing MSFS2020 i have had no issues whatsoever - its been the most reliable sim ever, plus no need for half the addons you needed to make fsx work properly
