RTX HDR screen capture.

RTX HDR screen capture.

I HDR calibrated my cheap HDR monitor after three years! and it was hard work. I then tried Nvidia RTX HDR to see how it would handle FS4 and the first attempt looked really good. The screen capture looks as if the highlights and shadows are expanded. There are tons of near white shades here and the near blacks show surprising detail, the tyre threads and engine fan blades are clearly visible. These same shades were very bright and perhaps darker on the computer monitor during live play.

The clouds were nice and bright 8)

RTX HDR gives an impression of true HDR with a wide range of ordinary games and video on a HDR monitor, even my cheap HDR10 model. It is free in the new Nvidia App. It is also very nice on YouTube.

Thank you for your advice, which is much appreciated!


I made two changes, including limiting the refresh rate to 60 FPS, and setting the graphics quality to medium, and the external camera rotations work smoothly.

However, I'm not satisfied, as this isn't normal with the hardware we're using.
I usually run everything in Ultra with V-SYNC enabled and anti-aliasing enabled, and on average, I run between 120 and 140 FPS, with a few exceptions.

On MSFS, I run at around 60 FPS, but there, it's normal given the overall density.

I had a look taking off and flying around jfk and crossing the field at low level I still got 60 fps but the cpu was running at 30% and the gpu at 80% at its lowest which at 4K means the computer was being cpu bound. Right over the city the cpu crept up again and I got frame rate drops to around 55 fps but it seemed smooth and pleasant (even with an Airbus A350).
The jfk scenery is exceptional so I will leave things as they are.
Away from New York the numbers were about 23 and 99. My cpu is an i7 4770K at 4.2 GHz with 8GB ram. They might get replaced before too long.

At Albany the cpu and gpu were running at 13% and 53%.

My card is an Nvidia 3070i 8GB with a 27" LG UltraGear OLED HDR/HDR10 (2560 x 1440) display with a max frame rate of 240Hz, however my card has a max frame rate of 165Hz. Everything is calibrated to Ultra, all airports run smoothly, except JFK?
I thought it might be the CPU, but I don't think so.
Perhaps a conflict with a nearby object, POIs, crane, or something else?

Perhaps try limiting your frame rates in the Nvidia settings, a flight sim does not need high frame rates. I run MSFS at 30 fps in-game and it looks perfectly fine, for Aerofly 60 fps in Nvidia settings is just my monitor’s rate but setting adaptive vsync at 30 fps looks good too. My monitor does not have g-sync so I keep to 60 or 30 in Nvidia settings.

I do use the detailed Nvidia settings based on performance guides that I’ve seen in YouTube videos. IPACS say use default settings but don’t define exactly what they are! I use a 8 GB rtx 2080 super so we should have broadly similar card performance. Over NYC in 4K and Ultra I have very normal ordinary smoothness at 60 fps, I feel like there is plenty of performance to spare. Aerofly should not be an excessively demanding ‘game’ so your hardware settings might be unnecessarily high?

(I had tried LaGuardia, I’ll have a look at JFK to see if there is a difference. I thought the city itself would be the most limiting).

Thanks for your feedback, yes I have already tested it too, overall the quality and rendering are much better, except for JFK which remains unchanged for me unfortunately. I know that this is not the cause, but I was hoping to have perhaps an improvement in the fluidity of the image, unfortunately this is not the case.;(

I'm maxed in settings, what frame rates are you using? I never use user add-ons.

Try it in HDR with camera rotations, exterior view at KJFK, and let me know your results, thanks.
As for me, it's still just as catastrophic with or without, with jerky images.

First class, smooth, frames solid (locked at 60 in Nvidia seettings), massive increase in 'white' building tones and almost blinding white JAL A350. Win win.

This is RTX HDR, it is not real HDR. It is a simulation to improve compatibility with HDR screens.
