Hey Rascal,
I installed FS 2004 and then FSX on Windows 11. Works flawlessly.
Don't be fooled, Windows 11 is faster and more stable than Win 10.
My hardware: Core I5, 8 GB memory, graphics AMD HD 6800, installed on 2nd disk Sata 2.
This is an Acer Aspire 7750G laptop
Everything great.
Maybe it helps you.
LG
