CKSURFGIRL,
My recommendation would be just to move on from MSFS. Your complaints for the most part will either fall on deaf ears or be taken as personal attacks or insults, or you will be blamed for trolling. Something was introduced in the UK update that started throttling performance and was blown wide open after WU3. There are plenty of people with high end hardware that have suffered with zero explanation other than repeatedly being told that the problem is with our computers.
I’ve moved on from MSFS and am extremely happy in doing so. XP11 with max settings, ortho and other lovely addons gets me fluid 60-100 fps wherever I fly. The laptop I had MSFS installed on that barely mustered 20fps after WU3 now has iRacing installed, fully maxed out at 200fps. So thanks to MSFS’ issues, I have found the love of sim racing again.
