If you have the game on Steam you can activate the display of FPS.
To my eyes your numbers seem to be very low fr your specs, you are getting something similar to me with better CPU, better GPU and more RAM.
And it is almost impossible to get more FPS on the 787 than the A320. It’s the first time I read such a thing 
It could be because most of my settings are on Ultra. I fly A320 with fps around 32-35 on the ground and close to 40-50 in the air with almost no stutters. That is why I keep Ultra settings. May be I should should change it to High instead
I have the very same PC, i9-9900K OC5GZ with a 2080ti and with the Longitude in heathrow I went from 15-20 fps to 30-35fps, Orbx´s Innsbruck from 35fps to 45-50 and smaller ones over 50. I´m really happy with this mod.

Real airliners such as the 747 and A320 run their screens at 20-25hz…
Not sure about the dreamliner but i highly doubt it is 144hz, maybe 30hz-60hz at most. Remember this is an industry where everything needs to be as cheap and low power consuming as possible.
You can find many RL A320Neo in-cockpit footage videos with some close-ups on the PFDs.
This is one: https://youtu.be/FODhSJucbK0
Another even clearer: https://youtu.be/ECV3IBkzZLc
The screens look pretty smooth and they probably run at 25fps, but I don’t think those are “normal” LCD displays, not like the ones we use for our PCs.
My screens are all black after doing this, any idea what i might be doing wrong? 
Did you edit the file or did you download the patch into your community folder?
If you edited the file roll back to the original and download the file that I posted before into your community folder. You are free to edit that to your like and it won’t overwrite any of your core files.
Btw: I haven’t found a way to change this ridiculous name in the forums but my name is Luis.
Cheers.
it’s ruined my fs2020
beware
thanks for nothing !!!
This is as safe as a patch can be. If you put it in the community folder then you can just delete it if you want to revert all changes. It only affects the display ratio of instruments so nothing can really go wrong.
well, I went ahead and changed the .js file and now the upper PDF screen(VS,IAS,AI) is stuttering.
even if i remove the .js file from its original location, the sim wont re-download it.
Works like a charm on my system. I decided to go for the middle and now have a stable 30fps at Charles de Gaulle on everything maxed 3840x1080 in the A320. Before that, it was 5fps less, and at this lower end, every single frame counts. 30fps is all I ever want as minimum
Delete the whole folder. It will then re download it
In the instructions you find in the first post I suggested to do a backup copy of the file before editing. If you don’t read the instructions it’s really all your fault 
It was enough to change the division factor to 1 (as stated over the first screenshot in my first post) to revert it to the original PFD (not PDF) frame rate

I’m running a 7600k @ 4.5Ghz with a 1060gtx 6GB, 16GB Ram on a 60Hz monitor. Which would be the correct file to download from the 3 for me to see an improvement? Does anyone run a similar setup who could advise? Appreciated thanks.
My A320 screens are all Black now…
Thanks, i dont know what i did but i just replaced the file wiht the default one and then tried again and worked. However the displays are seriously laggy, how can i manually change the refresh rate, i dont understand the logic in it
I konw, I figured it out.
Thanks.

Please read this chunk of the first post, which explains how to change the refresh rate based on the division coefficient:
Consider that Quality.high is the chunk of code used when you are in cockpit, the other quality options are for lower LODs (external views or drone camera based on distance from the plane).
The number you enter here if ((this.frameCount % 3 ) != 0) (3 in my case) is the glass cockpit instruments FPS subdivision coefficient based on your screen refresh rate (my screen is 144Hz so divided by 3 means the glass cockpit will work at 48 Hz, you can try different numbers based on your display Hz and CPU power).
