FSX has kinda been fased out by P3D now, and is kinda considered old, so there's that. But I know the age of the sim means little when it's flight sim. Some are still rocking FS2004
FSX is more situable for me, since the computer i have access in my house is WORSE than my laptop(R.I.P)
As crappy and as old as FSX is nowadays, there are still some machines out there that sim will kill. Make sure that your desktop is not a Dell optiplex with a Pentium toaster CPU in it
Intel(R) Core(TM) i5-2450M CPU@ 2.50 GhZ 8,00 GB RAM x64. It still runs GTA SA (Laggy) though, and also, this is my dad's computer... so i'm not free to install any game P.S: My dad is anti-games..... i wanted to die when my laptop died... as i would like to die if my mom dies xD
