Give this setting a try to improve your graphics in Flight sims

I tried it in Il2 and it seemed to work.  My framerate over Paris was rock steady at my 4K monitors max refresh of 60 with micro stutters.  Your mileage may vary....

 

It is a simple setting in Window  Settings/Display/Graphics

Good tip! I'll have to try on my Windows install. I still have a WIndows install just for MSFS.
