HDR stopped working after 4.2.0 Update

So, since they still haven't fixed this issue (Using Nvidia 3080 with a Dells2721 HDR monitor which works in all games but this and F1 games with HDR) there is a small bypass that can fix it atm for many. I also posted this a while ago in the F1 forum which seems to have helped many. Note that it might disable VRR, thats what you might have to live with until official fix.

You also do not need to download any other programs on your pc, very simple solution!

• Go into your Battlefield 2042 map, for me "steamapps\common\Battlefield 2042"
• Find your bf2042.exe
• Right click it and choose properties
• Compability
• And now click "Use legacy display icc color management"
• Click apply and restart the game

And now HDR should work much much much better. Probably this "fix" isn't for everyone but it is for me after having problems with this game for over a year with HDR, combined with the F1 games. They seem to use some old thing to hook into HDR which is problematic. With this step, the app, in this case "bf2042.exe" will be able to show more accurate colors and access the full color gamut. 

Its possible its tied to this error in Windows 11 https://www.reddit.com/r/Windows11/comments/qg8dcg/for_those_of_you_going_crazy_over_icc_profiles/

Which is using "GetICMProfile()" which isn't working any longer but "WcsGetDefaultColorProfile()" is the working one which may be the error, hopefully this will fix it for many of us until they choose to fix it. Also i've heard its because of Srgb and rgb color gamut that seems not work in a few games like this
