Hi chaps,
Just in case you're an MSFS 2020 addict like myself:
It can be quite time consuming to get the graphic settings optimized for your particular hardware setup.
I've tested all available settings in depth forth and back for a couple of days and finally managed to come up with a setup which works best in my case, meaning it gives almost perfect visual quality (¹) at reasonable good FPS (²) with minimum stuttering (³).
For reference, this is my hardware Setup:
CPU: Intel Core i5-9600K @4.8 GHz
Memory: 16 GB RAM (another 32 GB have been ordered - you will want to have at least 32 GB!), game is installed on 1TB SSD
GPU: ASUS Nvidia 2080 Super, 8GB
Monitor: Acer XB271HU, 2560x1440p, 144Hz G-SYNC
¹: You can run the game in "Ultra" Preset Mode all over, if you use 1080p resolution max. Anything above that (1440p or 4K for instance), no current hardware can give good FPS at Ultra settings.
²: Reasonable good FPS for MSFS 2020 are in the range of 30-60 FPS. My settings result in 45-60 FPS in all possible situations, including crowded cities with payware addon textures and buildings.
³: You can't get MSFS 2020 completely stutter-free. That's because of the gigantic amount of textures being used to the scenery. Deal with it.

Hope that helps a bit.
