For those of us with SDR (non-HDR) monitors and NVIDIA cards, right click on the desktop to open the NVIDIA Control Panel. Under Display, select Adjust desktop color settings. You'll find a slider labelled Gamma. Its default value should be 1.00. Change that to something in the vicinity of 0.8 or so, whatever works best for your eye. That will adjust the mid-tone brightness to something more acceptable than what MSOBO has provided in SU5.

Don't forget to set it back after you're done flying. If you like to produce videos for online viewing, this trick probably won't work, but maybe one day these folks are going to get themselves straightened out. What a shame.

I have an older Sony TV which is not HDR capable. But there is nonetheless an advanced TV-settings option to "Automatically Adjust Contrast Depending On Scene." Selecting that TV-settings option did miracles for me within the Sim. If your TV or monitor happens to have this feature -- as it probably does -- then enable it and most of your display problems will be instantly solved.

This is what I see after the hotfix.

There is a thread about it of sharing tweaks but there is no solution which is really satisfying..  

The metering problems (over exposition) are there since day1 early 2020 and are exemplified in VR even more (re: full screen average Luma - typical working simplification in 2D games - vs spot and/or weighted average Luma - more appropriate with or without gaze tracking).

The difference to me, before and after SU5, for the exposition problem, is that the game is now “tuned” for Xbox + HDR TV display. Not only many PC + monitor users don’t have HDR capable display devices, but the monitor and the TV might not be using the same gamma either. In addition, PC+monitors are calibrated for sRGB whereas HDR TV are calibrated for a wider color gamut.

The SU5 graphics changes are so much making me thinking of these:

“While the Rec. 2020 transfer function can be used for encoding, it is expected that most productions will use a reference monitor that has an appearance of using equivalent of gamma 2.4 transfer function”
https://en.wikipedia.org/wiki/Rec._2020

“SDR for HD video uses a system chromaticity (chromaticity of color primaries and white point) specified in Rec. 709 (same as sRGB). […] HDR is commonly associated to a Wide Color Gamut (a system chromaticity wider than BT.709)”
https://en.wikipedia.org/wiki/High-dynamic-range_video#Chromaticity

 

I believe therefore there is at least one solution to this problem with SU5: using an Xbox on a TV screen.

 

PS: having said this, it might just be as simple as a bug in the shader code which would scale the "ambient" light from the sun too much of course, but I don't know where I read it but it seems to me SU5 "exposition" was changed on purpose and I don't remember what was the reason.

PPS: here is a post with before/after pictures and the 1st couple of these are clearly showing a hard shadow under the aircraft although the sun is supposed to be somewhat hidden by the clouds:

Or spend almost as much on a HDR10 (not HDR 400) monitor with genuine 10 bit color.    Even then you may have issues as some monitors will not do both HDR and GSync/Freesync at the same time. Multiply that by three if you are thinking of building a multi screen sim pit as all the screens will need to be HDR10 and at least 50% more expensive as a result.

It is pretty clear they have optimised the game for best visuals on HDR Televisions.

Probably a good marketing decision as the good press of the "wow" factor of seeing the HDR optimised game on a large screen HDR TV will more than out weigh the odd complaint from users of older SDR PC technology who can just be labelled as recidivist users of legacy tech stuck in the past.

Indeed but exacerbated in SU5.

Amusingly, someone has started a change.org petition about this. Cannot hurt I suppose.

https://www.change.org/p/microsoft-flight-simulator-pc-community-restore-the-visual-fidelity-of-microsoft-flight-simulator-2020-pre-sim-update-5?utm_content=cl_sharecopy_30135521_en-AU%3A7&recruiter=1218449326&utm_source=share_petition&utm_medium=copylink&utm_campaign=share_petition

An OLED 4K 120Hz HDR TV like the 48" LG CX/C1 has been so good to me that I even abandoned VR for it. I don´t think there is anything better for flight-simulation at this point in time. Hopefully Asobo fixes the issue, though.

I  have found that if I change HDR on in the 49 inch Sony TV I use for flight simming from auto to on, then enable HDR in Windows and HDR10 in FS2020 and also increase colour saturation on the TV to compensate for a desaturating effect of having HDR on, I can indeed get clouds that are not too white and have realistic shadows. Unfortunately I also get an annoying wavy shimmering effect in the FS display particularly in forested areas.  This anomaly goes away when I revert to non HDR settings so that is where I am until something better comes along.
