YES !! and prior to SU5, many rushed out and upgraded to get 32GB of ram, because as what was needed, and now, MSFS has been squeezed into sub 16 GB.
I get it – Xbox has limited RAM, and it was a Great Achievement to compress MSFS to run in the X-BOX’s Fixed limited ram, BUT – why can’t MSFS running on a PC with 32GB+ of ram, make use of some of that ram, and run better than it would on sub 16GB ??
It does seem, that just like Pilots, MSFS has the attitude, “NO X-BOX left behind” , and every MSFS system is handicapped, so that it is a FAIR race with X_box, so X-Box will “NOT BE LEFT BEHIND” – because nobody want to buy a Looser, and MS wants to sell X-Boxes, and capture the Monopoly MS-Market, that currently is getting very much “LEFT BEHIND”.
