A few days ago I was running the simulator in my old configuration. Look:
Intel Core i7 8700K (stock)
Gigabyte Z370 AORUS Gaming 7
Corsair 16gb DDR4 3200 ram
GTX 1080ti AORUS Xtreme
ASUS ROG MONITOR - 2560-1440 - 144HZ G-Sync.
I ran the simulator with all the settings on ULTRA, at the monitor’s native resolution and had decent performance.
30 fps in cities and 70-80 fps in open places.
Strangely, the simulator only used the greatest potential of the graphics card when the camera was out of the cockpit. Inside the cabin the fps was low and the use of the GPU decreased a lot.
Thinking about improving the performance of the simulator I bought an RTX 3080 (ZOTAC TRINITY O.C.).
I used the DDU software to uninstall everything from the previous VGA and reinstalled all the drivers (Nvidia and monitor).
However, I did not reinstall MSFS.
All done, I realize that the performance has not improved at all. At some points it got worse.
I noticed that the luminous points, solar reflections and etc., were very bright and blurred.
Overall performance worsened, dropping around 10 fps in cities and 20 in open places.
What can I have done wrong?
Should I reinstall the simulator?
I always left G-Sync enabled. Should I leave it like this?
Thanks to all for your help.
