Personally I have been lucky so far, yes a few CTD's,  I bought Fs 2020 about 16 months ago, overall I have had very few problems, performance has been pretty good, very, very ;little stuttering, anyway I just wanted to share some of my settings, I surely get lots of better performance than FSX, which was a stutter problem from the get go.

My computer specs u can see down below  I do overclock 4.8ghz

Render Scaling-150, v-sync=on frames locked-30 DX-11 AA-TAA TLD-300, everything on Ultra in this category, buildings, trees, bushes, etc OLD-200 Volumetric clouds-Ultra Texture resolution-Ultra Water Waves=High AF 16x Texture Synthesis Ultra Shadow Maps 2048 Texture Shadows-1024 Shadow Maps-2048 Depth- Ultra Motion Blur Lens Correction and Lens Flare all OFF, Glass Cockpit-Medium

Hopefully, this might help some of u.  

As far as playing around with settings, these are basically the same settings since getting the sim  I can fly the Maddogx X from Boston to Toronto and no problem and also this is flytampa airports

I am no expert what so ever, just one of the lucky ones so far.

Waves=High AF

I thought that was a new setting for a moment. There's High then there's High AF ! 😁

from SU10 forward, i hope that the "Ultra" graphics settings will be renamed to "High AF" 😄

It should be shouldn't it? 😁

I reckon the X-Boxers would prefer that setting! 😆
