At true 4K with no FPS lock, almost all ultra settings, and Render Scale at 100, my frame rates fell from the mid 40s into the mid to low 20's when I would encounter multiple cloud layers with a spectrum of shades from white to very dark gray, to almost black.   

This is not my own screenshot but is characteristic of what I encountered yesterday, met by a significant loss of frame rate, especially when closer to this form of clouds than the aircraft was in this shot. The clouds I encountered ranged to a bit darker than what is seen here, and I was just below, at, or above the cloud tops, not under them as seen here.  Wish I had done a couple of screen captures myself.

I changed my MSFS options from my monitor's native 4K and 80 to 1440 with 100 render scaling, clouds still on Ultra, and my frame rates went back up from low to mid 20s to near 50.  And I could see no discernable difference in appearance in the sim.

You will get the same FPS and much better graphics by running native 4K and render scaling down around 70% .

By sending 1440p to a 4k screen you are forcing the screen to upscale which adds another level of processing with unpredictable results. It will work but is not optimal. 

As a rule of thumb always set the MSFS resolution to the native for the screen and use the render slider to change the workload on the GPU instead of messing with resolutions.

I just picked up a used but like new TCL 4 series 43". I was a little nervous on how my trusty old 1080TI would cope with the higher resolution so I spent the last few days testing. Previously I was running a 43" LG 1080P TV and could maintain 60fps with decent settings.

Long story short I settled on 4K in game with the render scale set to 70 and with a little tweaking I have been amazed that I can hit 60fps fairly consistently and the sim still looks great even in the A32NX. CPU usage sits around 50% with GPU usage at around 75% in the air. I did try the render scale on 100 and the monitor set to 30Hz & fps locked to 30, yes everything in the cockpit was a little clearer and looking ahead everything was smooth it is just panning or looking around with the mouse that I do not like. It is so much nicer at 60fps.

I paid $160 CDN for this TV and have been super happy, Just using it as a monitor is wonderful, everything is pin sharp. I would love a newer GPU as my 1080TI is the bottleneck right now but prices are still just insane and I am not sure if a 3070TI is a worthy upgrade for me. The 3080TI would seem a better fit but not at the current prices.
